- Configuration Options
-
- This code is designed so it will work correctly and completely by
- default. No configuration is necessary to make it work. None of the
- following #defines need to be enabled. The code works and is very
- portable with them all turned off.
-
- All configuration options (USEFULBUF_CONFIG_XXX)
-    1) Reduce code size
-    2) Improve efficiency
-    3) Both of the above
-
- The efficiency improvements are not large, so the main reason really
- is to reduce code size.
-
- */
-
-
-/*
- Endianness Configuration
-
- By default, UsefulBuf does not need to know what the endianness of
- the device is. All the code will run correctly on either big or
- little endian CPUs.
-
- Here's the recipe for configuring the endianness-related #defines
- to use more efficient CPU/OS/compiler dependent features to reduce
- code size. Note these only affect the integer arrays (tagged
- arrays) feature of QCBOR. All other endianness handling in
- QCBOR is integrated with code that also handles alignment and
- preferred encoding.
-
- The first option is to not define anything. This will work fine on
- with all CPU's, OS's and compilers. The code for encoding
- integers will be a little larger and slower.
-
- If your CPU is big-endian then define USEFULBUF_CONFIG_BIG_ENDIAN. This
- will give the most efficient code for big-endian CPUs. It will be small
- and efficient because there will be no byte swapping.
-
- Try defining USEFULBUF_CONFIG_HTON. This will work on most CPU's,
- OS's and compilers, but not all. On big-endian CPUs this should give
- the most efficient code, the same as USEFULBUF_CONFIG_BIG_ENDIAN
- does. On little-endian CPUs it should call the system-defined byte
- swapping method which is presumably implemented efficiently. In some
- cases, this will be a dedicated byte swap instruction like Intel's
- bswap.
-
- If USEFULBUF_CONFIG_HTON works and you know your CPU is
- little-endian, it is also good to define
- USEFULBUF_CONFIG_LITTLE_ENDIAN.
-
- if USEFULBUF_CONFIG_HTON doesn't work and you know your system is
- little-endian, try defining both USEFULBUF_CONFIG_LITTLE_ENDIAN and
- USEFULBUF_CONFIG_BSWAP. This should call the most efficient
- system-defined byte swap method. However, note
- https://hardwarebug.org/2010/01/14/beware-the-builtins/.  Perhaps
- this is fixed now. Often hton() and ntoh() will call the built-in
- __builtin_bswapXX()() function, so this size issue could affect
- USEFULBUF_CONFIG_HTON.
-
- Last, run the tests. They must all pass.
-
- These #define config options affect the inline implementation of
- UsefulOutBuf_InsertUint64() and UsefulInputBuf_GetUint64().  They
- also affect the 16-, 32-bit, float and double versions of these
- instructions. Since they are inline, they size effect is not in the
- UsefulBuf object code, but in the calling code.
-
- Summary:
-   USEFULBUF_CONFIG_BIG_ENDIAN -- Force configuration to big-endian.
-   USEFULBUF_CONFIG_LITTLE_ENDIAN -- Force to little-endian.
-   USEFULBUF_CONFIG_HTON -- Use hton(), htonl(), ntohl()... to
-     handle big and little-endian with system option.
-   USEFULBUF_CONFIG_BSWAP -- With USEFULBUF_CONFIG_LITTLE_ENDIAN,
-     use __builtin_bswapXX().

-/**
- @file UsefulBuf.h
-
- The goal of this code is to make buffer and pointer manipulation
- easier and safer when working with binary data.
-
- The @ref UsefulBuf, @ref UsefulOutBuf and @ref UsefulInputBuf
- structures are used to represent buffers rather than ad hoc pointers and
- lengths.
-
- With these it will often be possible to write code that does little
- or no direct pointer manipulation for copying and formatting
- data. For example, the QCBOR encoder was written using these and
- has no less pointer manipulation.
-
- While it is true that object code using these functions will be a
- little larger and slower than a white-knuckle clever use of pointers
- might be, but not by that much or enough to have an effect for most
- use cases. For security-oriented code this is highly
- worthwhile. Clarity, simplicity, reviewability and are more
- important.
-
- There are some extra sanity and double checks in this code to help
- catch coding errors and simple memory corruption. They are helpful,
- but not a substitute for proper code review, input validation and
- such.
-
- This code consists of a lot of inline functions and a few that are
- not.  It should not generate very much object code, especially with
- the optimizer turned up to @c -Os or @c -O3.
- */
-
-
-/**
- @ref UsefulBufC and @ref UsefulBuf are simple data structures to hold
- a pointer and length for binary data.  In C99 this data structure can
- be passed on the stack making a lot of code cleaner than carrying
- around a pointer and length as two parameters.
-
- This is also conducive to secure coding practice as the length is
- always carried with the pointer and the convention for handling a
- pointer and a length is clear.
-
- While it might be possible to write buffer and pointer code more
- efficiently in some use cases, the thought is that unless there is an
- extreme need for performance (e.g., you are building a
- gigabit-per-second IP router), it is probably better to have cleaner
- code you can be most certain about the security of.
-
- The non-const @ref UsefulBuf is usually used to refer a buffer to be
- filled in.  The length is the size of the buffer.
-
- The const @ref UsefulBufC is usually used to refer to some data that
- has been filled in. The length is amount of valid data pointed to.
-
- A common use is to pass a @ref UsefulBuf to a function, the function
- fills it in, the function returns a @ref UsefulBufC. The pointer is
- the same in both.
-
- A @ref UsefulBuf is null, it has no value, when @c ptr in it is @c NULL.
-
- There are utility functions for the following:
-  - Initializing
-  - Create initialized const @ref UsefulBufC from compiler literals
-  - Create initialized const @ref UsefulBufC from NULL-terminated string
-  - Make an empty @ref UsefulBuf on the stack
-  - Checking whether a @ref UsefulBuf is null, empty or both
-  - Copying, copying with offset, copying head or tail
-  - Comparing and finding substrings
-
- See also @ref UsefulOutBuf. It is a richer structure that has both
- the size of the valid data and the size of the buffer.
-
- @ref UsefulBuf is only 16 or 8 bytes on a 64- or 32-bit machine so it
- can go on the stack and be a function parameter or return value.
-
- Another way to look at it is this. C has the NULL-terminated string
- as a means for handling text strings, but no means or convention for
- binary strings. Other languages do have such means, Rust, an
- efficient compiled language, for example.
-
- @ref UsefulBuf is kind of like the Useful Pot Pooh gave Eeyore on his
- birthday.  Eeyore's balloon fits beautifully, "it goes in and out
- like anything".

-/**
- UsefulOutBuf is a structure and functions (an object) for serializing
- data into a buffer when encoding a network protocol or writing data
- to file.
-
- The main idea is that all the pointer manipulation is performed by
- @ref UsefulOutBuf functions so the caller doesn't have to do any
- pointer manipulation.  The pointer manipulation is centralized.  This
- code will have been reviewed and written carefully so it spares the
- caller of much of this work and results in safer code with less work.
-
- The @ref UsefulOutBuf methods that add data to the output buffer
- always check the length and will never write off the end of the
- output buffer. If an attempt to add data that will not fit is made,
- an internal error flag will be set and further attempts to add data
- will not do anything.
-
- There is no way to ever write off the end of that buffer when calling
- the @c UsefulOutBuf_AddXxx() and @c UsefulOutBuf_InsertXxx()
- functions.
-
- The functions to add data do not return an error. The working model
- is that all calls to add data are made without an error check. Errors
- are just checked for once after all the data has been added before the
- and before serialized data is to be used. This makes the calling code
- cleaner.
-
- There is a utility function to get the error status anytime along the
- way for a special circumstance. There are functions to see how much
- room is left and see if some data will fit too, but their use is
- generally not necessary.
-
- The general call flow is:
-
-    - Initialize by calling @ref UsefulOutBuf_Init(). The output
-      buffer given to it can be from the heap, stack or
-      otherwise. @ref UsefulOutBuf_MakeOnStack is a convenience macro
-      that makes a buffer on the stack and initializes it.
-
-    - Call methods like UsefulOutBuf_InsertString(),
-      UsefulOutBuf_AppendUint32() and UsefulOutBuf_InsertUsefulBuf()
-      to output data. The append calls add data to the end of the
-      valid data. The insert calls take a position argument.
-
-    - Call UsefulOutBuf_OutUBuf() or UsefulOutBuf_CopyOut() to see
-      there were no errors and to get the serialized output bytes.
-
- @ref UsefulOutBuf can be used in a size calculation mode to calculate
- the size of output that would be generated. This is useful to
- calculate the size of a buffer that is to be allocated to hold the
- output. To use @ref UsefulOutBuf in this mode, call
- UsefulOutBuf_Init() with the @c Storage @ref UsefulBuf as
- @c (UsefulBuf){NULL,MAX_UINT32}. Then call all the Insert and Add
- functions. No attempt will made to actually copy data, so only the
- lengths have to be valid for these calls.
-
- Methods like UsefulOutBuf_InsertUint64() always output in network
- bytes order (big endian).
-
- The possible errors are:
-  - The @ref UsefulOutBuf was not initialized or was corrupted.
-
-  - An attempt was made to add data that will not fit.
-
-  - An attempt was made to insert data at a position beyond the end of
-    the buffer.
-
-  - An attempt was made to insert data at a position beyond the valid
-    data in the buffer.
-
- Some inexpensive simple sanity checks are performed before every data
- addition to guard against use of an uninitialized or corrupted
- UsefulOutBuf.
-
- This has been used to create a CBOR encoder. The CBOR encoder has
- almost no pointer manipulation in it, is easier to read, and easier
- to review.
-
- A @ref UsefulOutBuf is small and can go on the stack:
-   - 32 bytes (27 bytes plus alignment padding) on a 64-bit machine
-   - 16 bytes (15 bytes plus alignment padding) on a 32-bit machines

- @ref UsefulInputBuf is the counterpart to @ref UsefulOutBuf and is
- for parsing data read or received.  Initialize it with the data from
- the network. Then use the functions here to get data chunks of
- various types. A position cursor is maintained internally.
-
- As long as the functions here are used, there will never be a
- reference off the end of the given buffer. This is true even if they
- care called incorrectly, an attempt is made to seek of the end of the
- buffer, etc. This makes it easier to write safe and correct code.
- For example, the QCBOR decoder implementation is safer and easier to
- review through its use of @ref UsefulInputBuf.
-
- @ref UsefulInputBuf maintains an internal error state.  The
- intended use is that data chunks can be fetched without error
- checking until the end.  Once data has been requested off the end of
- the buffer, the error state is entered. In the error state the
- @c UsefulInputBuf_GetXxxx() functions return 0, or @c NULL or
- @ref NULLUsefulBufC. As long as null are not dereferenced, the
- error check can be put off until the end, simplifying the calling
- code.
-
- The integer and float parsing expects network byte order (big
- endian).  Network byte order is what is used by TCP/IP, CBOR and most
- internet protocols.
-
- Lots of inline functions are used to keep code size down. The code
- optimizer, particularly with the @c -Os or @c -O3, also reduces code
