use socketpair(2) instead of pipe(2) for bi-directional communication
On Linux, pipes returned from pipe(2) only work in one direction. This broke 'got clone' over ssh in the -portable version because got-fetch-pack assumes it can use its fetchfd for both reading and writing. I wrote a complicated diff to use two pipe(2) calls instead of one, but millert suggested a simpler solution: Use socketpair(2) instead of pipe(2). ok millert jrick tracey

Stop including <sys/syslimits.h> directly.
POSIX says the limits defined there are available from <limits.h>, which almost all affected source files already included anyway. ok millert stsp
