    Add a shared "port" directory for POSIX functions needed by multiple host
tools (getopt/mkstemps) and import the one and only getopt from glibc.
    
    This finally fixes our duplicated getopt functions from different sources and gives us
an up to date and the most compatible implementation.
    isohybrid actually relies on a glibc-specific getopt behavior that we previously
hacked into the reactos_support_code.c implementation derived from BSD/mingw-w64.
    widl also needs getopt and previously used an even older BSD-derived code.

+/* Scan elements of ARGV (whose length is ARGC) for option characters
+   given in OPTSTRING.
+
+   If an element of ARGV starts with '-', and is not exactly "-" or
"--",
+   then it is an option element.  The characters of this element
+   (aside from the initial '-') are option characters.  If 'getopt'
+   is called repeatedly, it returns successively each of the option characters
+   from each of the option elements.
+
+   If 'getopt' finds another option character, it returns that character,
+   updating 'optind' and 'nextchar' so that the next call to
'getopt' can
+   resume the scan with the following option character or ARGV-element.
+
+   If there are no more option characters, 'getopt' returns -1.
+   Then 'optind' is the index in ARGV of the first ARGV-element
+   that is not an option.  (The ARGV-elements have been permuted
+   so that those that are not options now come last.)
+
+   OPTSTRING is a string containing the legitimate option characters.
+   If an option character is seen that is not listed in OPTSTRING,
+   return '?' after printing an error message.  If you set 'opterr' to
+   zero, the error message is suppressed but we still return '?'.
+
+   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+   so the following text in the same ARGV-element, or the text of the following
+   ARGV-element, is returned in 'optarg'.  Two colons mean an option that
+   wants an optional arg; if there is text in the current ARGV-element,
+   it is returned in 'optarg', otherwise 'optarg' is set to zero.
+
+   If OPTSTRING starts with '-' or '+', it requests different methods of
+   handling the non-option ARGV-elements.
+   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+   Long-named options begin with '--' instead of '-'.
+   Their names may be abbreviated as long as the abbreviation is unique
+   or is an exact match for some defined option.  If they have an
+   argument, it follows the option name in the same ARGV-element, separated
+   from the option name by a '=', or else the in next ARGV-element.
+   When 'getopt' finds a long-named option, it returns 0 if that option's
+   'flag' field is nonzero, the value of the option's 'val' field
+   if the 'flag' field is zero.
+
+   The elements of ARGV aren't really const, because we permute them.
+   But we pretend they're const in the prototype to be compatible
+   with other systems.
+
+   LONGOPTS is a vector of 'struct option' terminated by an
+   element containing a name which is zero.
+
+   LONGIND returns the index in LONGOPT of the long-named option found.
+   It is only valid when a long-named option has been found by the most
+   recent call.
+
+   If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+   long-named options.  */

-@deftypefn Replacement int mkstemps (char *@var{template}, int @var{suffix_len})
-
-Generate a unique temporary file name from @var{template}.
-@var{template} has the form:
-
-@example
-   @var{path}/ccXXXXXX@var{suffix}
-@end example
-
-@var{suffix_len} tells us how long @var{suffix} is (it can be zero
-length).  The last six characters of @var{template} before @var{suffix}
-must be @samp{XXXXXX}; they are replaced with a string that makes the
-filename unique.  Returns a file descriptor open on the file for
-reading and writing.
