Harmonize configure and CMake build system (part 1).

The files "config.h" generated by configure and CMake are now almost
identical, except a few comments and some still missing or failing
config tests, for instance checks for some functions in libraries.
[Note: tested and compared on Linux.]

configh.cmake.in: Fixed many #cmakedefine and #cmakedefine01 statements
  so they #define their variables as 0 or 1, or /* #undef */ it, resp.,
  as it is done in the configure build.

Added tests:
  - libXrender

Fixed tests:
  - function glXGetProcAddressARB

Todo (still failing tests in CMake):
  - HAVE_PNG_GET_VALID
  - HAVE_PNG_SET_TRNS_TO_ALPHA
  - HAVE_DLSYM

Other remaining issues:
  - compiler flags introduced in configure/make build
  - HAVE_SYS_NDIR_H - maybe missing test in configure ?
  - HAVE_SYS_DIR_H  - maybe missing test in configure ?
  - HAVE_NDIR_H     - maybe missing test in configure ?
  - WORDS_BIGENDIAN and #include <mac_endianness.h> ...
    i.e. Mac OS X specific #include needed or not ?
