Revert changes done to 'make apidoc' target

This partially reverts 1989caf71c1d4 (only the changes to Makefile and
CMakeLists, the addition to scripts/config.pl is kept).

Modifying config.h in the apidoc target creates a race condition with

    make -j4 all apidoc

where some parts of the library, tests or programs could be built with the
wrong config.h, resulting in all kinds of (semi-random) errors. Recent
versions of CMake mitigate this by adding a .NOTPARALLEL target to the
generated Makefile, but people would still get errors with older CMake
versions that are still in use (eg in RHEL 5), and with plain make.

An additional issue is that, by failing to use cp -p, the apidoc target was
updating the timestamp on config.h, which seems to cause further build issues.

Let's get back to the previous, safe, situation. The improved apidoc building
will be resurrected in a script in the next commit.
