Corinna Vinschen c90b20192d Cygwin: getgrent/getpwent: avoid local enumeration on DCs
...if we're supposed to enumerate the AD accounts anyway.  This
avoids some useless duplication.

Corinna Vinschen 15e82eef3a Cygwin: getgrent: fix local SAM enumeration on domain member machines
Don't skip output of local SAM groups on domain member machines.
They can have valid, user-defined groups in their SAM.  Just
skip builtin groups if we're enumerating AD as well.

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.

Corinna Vinschen 50ad198085 Cygwin: Add 'fallthrough' pseudo keyword for switch/case use
This patch has been inspired by the Linux kernel patch

  294f69e662d1 compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case use

written by Joe Perches <joe AT perches DOT com> based on an idea from
Dan Carpenter <dan DOT carpenter AT oracle DOT com>.  The following text
is from the original log message:

Reserve the pseudo keyword 'fallthrough' for the ability to convert the
various case block /* fallthrough */ style comments to appear to be an
actual reserved word with the same gcc case block missing fallthrough
warning capability.

All switch/case blocks now should end in one of:

	break;
	fallthrough;
	goto <label>;
	return [expression];
	continue;

In C mode, GCC supports the __fallthrough__ attribute since 7.1,
the same time the warning and the comment parsing were introduced.

Cygwin-only: add an explicit -Wimplicit-fallthrough=5 to the build
flags.
