While both long and long long are 64-bits on x86_64, they are distinct types,
and long was used prior to commit 477463a2011ba81907a753df9ce7a71b6563db54.
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.

Initializing a pointer to struct __locale_t to point to a string "C"
is not such a bright idea in the long run...

Don't use global variables. This allows to call loadlocale from
the yet to be created newlocale().
Rename _thr_locale_t to __locale_t (these locales are not restricted
to threads so the name is misleading).
Along these lines, fix _set_ctype to take a __locale_t as parameter.

The _reent members _current_category and _current_locale are not
used at all. _current_locale is set to "C" in various points of
the code but its value is just as unused as _current_category.
This patch redefines these members without changing the size of the
structure to allow for an implementation of per-thread locales per
POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in
subsequent function calls).

The proper location for these functions has always been <stdio.h>, however
XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>. cuserid
was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid
declaration in <unistd.h> was made optional and obsolete in SUSv4.

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.

Resurrect <machine/_user_types.h> for use in <sys/types.h>. Newlib

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.

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

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.

Each version of SUS specifies a different value for _POSIX_VERSION,
_POSIX2_VERSION, and _XOPEN_VERSION. glibc also changes the value
of the other _POSIX2_ variables but not the _POSIX_* variables.
_POSIX_TIMERS should be set to a version number, not just 1.
The _POSIX_V7_* macros were missing, which was not noticed because
the V6 values were aliased in sysconf (<unistd.h>).

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).
