This commit makes the file config.h generated by CMake 100% compatible
with the one generated by autoconf/configure.
Fixes in this commit:
- Set FLTK_DATADIR and FLTK_DOCDIR with the same default values.
Note: needs some cleanup, option values are not clear, '/fltk'
is currently appended in export.cmake (needs improvement).
- Simulation of autoconf macro AC_HEADER_DIRENT for correct
definition of only one 'dirent' header file.
- Fix more function checks:
- dlsym
- png_get_valid
- png_set_tRNS_to_alpha
- Improve "Big Endian" check for __APPLE__ (mac_endianness.h).

CMake Warning (dev) at CMake/export.cmake:48 (set):
Policy CMP0053 is not set: Simplify variable reference and escape sequence
evaluation. Run "cmake --help-policy CMP0053" for policy details. Use the
cmake_policy command to set the policy and suppress this warning.
Changed old-style @variable@ replacement to ${variable}.
