libc: initial import from Harvey
Note that libc is what distinguish "native" software from "non-native" in Jehanne: further C libraries can be ported to Jehanne, but this libc will remain the main building block of the system. Also note that a few files have not been ported from Harvey: - 9sys/pushtls.c - port/rijndael.c - port/rijndael.tbl - port/sha2.c Pushtls.c depends on libmp and libsec so libc is not the appropriate place for it. The other three will be moved to libsec.
