Subject: Make FL_ABI_VERSION configurable (STR #3161).

This commit adds the configure option --with-abiversion and the CMake option
OPTION_ABI_VERSION. Both options can be set e.g. to 10304 to build with
FL_ABI_VERSION = 10304 (FLTK 1.3.4).

For IDE builds there are new files ide/<IDE-NAME>/FL/abi-version.h that
can be edited to change the ABI version before the FLTK lib is built.
Note that this file MUST be copied to the include/FL directory if the
IDE-built library is to be installed.

The default is FL_ABI_VERSION = FL_MAJOR*10000 + FL_MINOR*100 + 0, i.e.
10300 for all FLTK 1.3.x versions to keep binary compatibility (ABI).

Todo: more tests and more documentation.
