process.c: tmp buffer instead of alloca
* process.c (OBJ2UID1, OBJ2GID1): separate from OBJ2UID and
OBJ2GID respectively, need given buffers.
* process.c (OBJ2UID, OBJ2GID): no longer need PREPARE_GETPWNAM
and PREPARE_GETGRNAM.
* process.c (obj2uid, obj2gid): use tmp buffer instead of alloca
to get rid of potential stack overflow.
* process.c (obj2uid, obj2gid): now getpwnam_r() and getgrnam_r()
may need larger buffers than sysconf values, so retry with
expanding the buffer when ERANGE is returned. [ruby-core:61325] [Bug #9600]
