Add library setup and teardown APIs

Add the following two functions to allow platform setup and teardown
operations for the full library to be hooked in:

* mbedtls_platform_setup()
* mbedtls_platform_teardown()

An mbedtls_platform_context C structure is also added and two internal
functions that are called by the corresponding setup and teardown
functions above:

* mbedtls_internal_platform_setup()
* mbedtls_internal_plartform_teardown()

Finally, the macro MBEDTLS_PLATFORM_SETUP_ALT is also added to allow
mbedtls_platform_context and internal function to be overriden by the
user as needed for a platform.
