Apparently nothing tests GETK/GETKQ, so tests still have to be added. 1.6 doesn't have GATK/GATKQ because the membase folks didn't need it. I'm adding them for completeness and because I don't want to argue about why people can't have it. If you're reading this, please use opaques :)
Some C compilers understand the syntax we use in memcached, but do not ship stdbool.h or stdint.h. According to C99 inttypes.h contains the formatting macros we use (PRInn) and is supposed to include stdint.h. This patch tries to detect stdbool.h and inttypes.h and tries to include them from config.h
Also separated much of the headers that may be interesting to client implementors into a separate header file.
