Corinna Vinschen acc5f02ce8 Throughout Cygwin, use u_intN_t or uintN_t
Don't use u_char, u_short, u_int or u_long in Cygwin, unless it refers
to the Winsock types.  Use u_intN_t in BSD-based sources, unsigned char
where strings are concerned, uintN_t otherwise.  Also:

	* net.cc: Fix comment, we're not using u_long anymore.

Corinna Vinschen b1b46d4580 Drop usage of old-age BSD types in generically used Cygwin headers
u_char, u_short, u_int, u_long are BSD-only types.  Remove them from
Cygwin headers which are supposed to be used in a non-BSD scenario.
Drop special Cygwin handling of those types in sys/types.h.

newlib:
	* libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop
	Cygwin exception.

cygwin:
	* fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change
	in include/asm/socket.h.  Continue using u_long since that's the
	MS type here.
	* include/asm/socket.h: Since the type given in _IOR/_IOW macros
	is only used for its sizeof, replace u_long with equivalent long.
	* netdb.h (getnetbyaddr): Fix prototype.
	* netinet/ip.h: Replace old BSD-only types with generically defined
	old BSD types (u_char -> u_int8_t, etc).
	* netinet/tcp.h: Ditto.
	* netinet/udp.h: Ditto.

The u_intN_t types are BSD types but sanctioned by POSIX.  They are

	* libc/include/sys/types.h: Drop outdated __INTTYPES_DEFINED__

Corinna Vinschen 59b3bd2aa6 Only allow enabled groups as primary group
So far any group in the user's token could be used as primary group.
Windows doesn't check if the primary group is enabled or not, it just
has no meaning.  From a POSIXy point of view it can lead to weird

Corinna Vinschen 155a1ec5fb Allocate temporary TOKEN_GROUP arrays using TLS
A user token can be up to 64K in size.  The group list might take a lot
of that so use tmp_pathbuf allocated space rather than stack space
allocted via alloca.  In create_token the TOKEN_GROUP was allocated via
malloc, but the code is needlessly complicated.  Simplify by using
tmp_pathbuf as well.

	* sec_auth.cc (verify_token): Allocate TOKEN_GROUP via tmp_pathbuf.

Corinna Vinschen e42f66d00f Remove ill-advised cygwin_props
Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.

Other than that, cygwin_props were meant to be used for some other global
settings which never took place.  There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.

This patch removes the cygwin_props entirely, including the related
settings in cygcheck.

	* cygprops.h: Remove file.
	* globals.cc (cygwin_props): Remove.
	* cygheap.cc (init_cygheap::init_installation_root): Drop removing
