Cygwin: simplify some function names
Remove "32" or "64" from each of the following names: acl32,

acltomode32, acltopbits32, acltotext32, facl32, fchown32, fcntl64,
fstat64, _fstat64, _fstat64_r, ftruncate64, getgid32, getgrent32,

setegid32, seteuid32, setgid32, setgroups32, setregid32, setreuid32,
setuid32, stat64, _stat64_r, truncate64.
Remove prototypes and macro definitions of these names.
Remove "#ifndef __INSIDE_CYGWIN__" from some headers so that the new
names will be available when compiling Cygwin.
Remove aliases that are no longer needed.
Include <unistd.h> in fhandler_clipboard.cc for the declarations of
geteuid and getegid.
