Add __nl_item to <sys/_types.h> for FreeBSD compatibility. Use it in
<langinfo.h> and the Cygwin <nl_types.h>. Make the enum __nl_item in
<langinfo.h> anonymous.

In order to avoid the year 2038 problem, define time_t to a signed
integer with at least 64-bits. The type for time_t can be forced to
long with the --enable-newlib-long-time_t configure option or with the
_USE_LONG_TIME_T system configuration define.

While both long and long long are 64-bits on x86_64, they are distinct types,
and long was used prior to commit 477463a201.
Changing this breaks the linking of previously compiled C++ functions with
off_t arguments on 64-bit Cygwin with newly compiled code, as the mangling of
long (l) and long long (x) differ.

The following testcase:
$ cat > test.c <<EOF
#include <sys/select.h>
#include <sys/time.h>
EOF
$ gcc -c test.c
emits the following error:
/usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor
e ‘_fpos64_t’
_fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
^
The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else. sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario. So sys/_types.h has to make sure to get the configuration
info by itself.

Various FreeBSD source and header files need a typedef __size_t via
<sys/_types.h>. Unfortunately the GCC provided <stddef.h> uses
#if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \
|| defined(__DragonFly__) \
|| defined(__FreeBSD_kernel__)
/* __size_t is a typedef on FreeBSD 5, must not trash it. */
#elif defined (__VMS__)
/* __size_t is also a typedef on VMS. */
#else
#define __size_t
#endif
and therefore defines __size_t on Newlib targets which would trash a
__size_t typedef. Include <stddef.h> before <sys/_types.h> in
<sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround.

Add __va_list to <sys/_types.h> for BSD compatibility. In FreeBSD this
typedef is provided by the various architecture-specific
<machine/_types.h> in a copy and paste manner.

Newlib defines defaults for internal types via <sys/_types.h> and uses
<machine/_types.h> to let targets define their own type if necessary.
Previously for example
#ifndef __dev_t_defined
typedef short __dev_t;
#endif
However, the __*_t_defined pattern conflicts with the glibc type guard
pattern for user types, e.g. dev_t in this example. Introduce a
__machine_*_t_defined pattern for internal types (defined by
<machine/_types.h>, used by <sys/_types.h>). For example
#ifndef __machine_dev_t_defined
typedef short __dev_t;
#endif

Remove off_t typedef from cygwin/types.h thus relying on sys/types.h.
Introduce winsup/cygwin/machine/_types.h and move some types shared
with newlib into it. Get rid of their definition in cygwin/types.h.
Add same handling for __key_t/key_t as for the other types.

This change solves a glibc/BSD compatibility problem.
glibc and BSD use double underscore types for internal types. The Linux
port of Newlib uses some glibc provided internal type definitions which
are not protected by guard defines, e.g. __off_t. To avoid a conflict
Newlib uses single underscore types for some internal types, e.g.
_off_t. However, for BSD compatibility we have to define the internal
types with double underscore names in <sys/_types.h>.
The header file <machine/types.h> is Newlib-specific. It was used
instead of <sys/_types.h> to provide the internal type definitions
_CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t. Move
these definitions to <sys/_types.h> (there exist two instances of this
file, one for Linux and one for all other targets). This makes the
_HAVE_SYSTYPES configuration define obsolete (could possibly break the
__RDOS__ target). Use the standard <sys/_types.h> include throughout.
Move __loff_t defintion to default (non-Linux) <sys/_types.h>. Define
it via _off64_t to avoid a dependency on the compiler.
Provide the __off_t definition via default (non-Linux) <sys/_types.h>
based on _off_t for all systems except Cygwin. For Cygwin use _off64_t.
Define off_t via __off_t.
Provide the __pid_t definition via default (non-Linux) <sys/_types.h>.
This prevents a potential __pid_t and pid_t incompatibility. Add BSD
guard defines for pid_t.
