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.

This option is marked as advanced and only available with CMake >= 3.0.

This flag is not needed and not used by fltk-config created by configure.
It is only used internally, and for this reason it is in config.h.

Also change our fallback cursors to use this method, so that fallback
cursors are handled in a platform independent manner. STR #2660.
