Clean up CMake header and type checks.
Unused macros: HAVE_DLFCN_H, HAVE_INTTYPES_H, HAVE_MEMORY_H, HAVE_STDLIB_H, HAVE_STRINGS_H, HAVE_STRING_H, HAVE_SYS_BYTESWAP_H, HAVE_SYS_STAT_H, HAVE_SYS_TYPES_H, HAVE_UNISTD_H. Used but never set macros: HAVE_LIBLZF, HAVE_LIBQUICKLZ. These only gate conditional includes. The code that takes advantage of them was removed. Unused types: ssize_t. The testing code uses HAVE_FUNC_MMAP, which was not wired in the CMake build, causing a whole test to be skipped.
