Ken Brown 2d9b48760c Cygwin: simplify some function names
Remove "32" or "64" from each of the following names: acl32,
aclcheck32, aclfrommode32, aclfrompbits32, aclfromtext32, aclsort32,
acltomode32, acltopbits32, acltotext32, facl32, fchown32, fcntl64,
fstat64, _fstat64, _fstat64_r, ftruncate64, getgid32, getgrent32,
getgrgid32, getgrnam32, getgroups32, getpwuid32, getpwuid_r32,
getuid32, getuid32, initgroups32, lseek64, lstat64, mknod32, mmap64,
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.

Ken Brown 7c0de0af97 Cygwin: remove some 32-bit-only function definitions
Remove the definitions of the following: acl, aclcheck, aclfrommode,
aclfrompbits, aclfromtext, aclsort, acltomode, acltopbits, acltotext,
chown, fchown, _fcntl, fstat, _fstat_r, ftruncate, getegid, geteuid, getgid,
getgrent, getgrgid, getgrnam, getgroups, getpwduid, getpwuid,
getpwuid_r, getuid, initgroups, lacl, lacl32, lchown, lseek, lstat,
mknod, mmap, setegid, seteuid, setgid, setgroups, setregid, setreuid,
setuid, stat, _stat_r, truncate.

[For most of these, the corresponding 64-bit entry points are obtained
by exporting aliases.  For example, acl is an alias for acl32, and
truncate is an alias for truncate64.]

Remove the following structs and all code using them (which is 32-bit
only): __stat32, __group16, __flock32, __aclent16_t.

Remove the typedefs of __blkcnt32_t __dev16_t, __ino32_t, which are
used only in code that has been removed.

Put the typedefs of __uid16_t and __gid16_t in one header, instead of
one header if __INSIDE_CYGWIN__ is defined and a different header
otherwise.

Ken Brown 5b8358e6ed Cygwin: remove the OPEN_MAX_MAX macro
Replace all occurrences of OPEN_MAX_MAX by OPEN_MAX, and define the
latter to be 3200, which was the value of the former.  In view of the
recent change to getdtablesize, there is no longer a need to
distinguish between these two macros.
