This patch adds the long double functions missing in newlib to Cygwin.
Apart from some self-written additions (exp10l, finite{f,l}, isinf{f,l},
isnan{f,l}, pow10l) the files are taken from the Mingw-w64 math lib.
Minor changes were required, e.g. substitue _WIN64 with __x86_64__ and
fixing __FLT_RPT_DOMAIN/__FLT_RPT_ERANGE for Cygwin.
Cygwin:
* math: New subdir with math functions.
* Makefile.in (VPATH): Add math subdir.
(MATH_OFILES): List of object files collected from building files in
math subdir.
(DLL_OFILES): Add $(MATH_OFILES).
${CURDIR}/libm.a: Add $(MATH_OFILES) to build.
* common.din: Add new functions from math subdir.
* i686.din: Align to new math subdir. Remove functions now commonly
available.
* x86_64.din: Ditto.
* math.h: math.h wrapper to define mingw structs used in some files in
math subdir.
* include/cygwin/version.h: Bump API minor version.
newlib:
* libc/include/complex.h: Add prototypes for complex long double
functions. Only define for Cygwin.
* libc/include/math.h: Additionally enable prototypes of long double
functions for Cygwin. Add Cygwin-only prototypes for dreml, sincosl,
exp10l and pow10l. Explain why we don't add them to newlib.
* libc/include/tgmath.h: Enable long double handling on Cygwin.

The inclusion of <sys/cygwin.h> by <sys/shm.h>, besides causing namespace
pollution, also makes it very difficult to get the WINVER-dependent parts
of the former. This affects code (such as x11vnc -unixpw_nis) which use
both SysV shared memory (e.g. the X11 MIT-SHM extension) and user password
authentication.
getpagesize is the simplest function to retreive this information, but it
is a legacy function and would also pollute the global namespace. The LSB
lists another form which is in the implementation-reserved namespace:

GCCs builtin functions are mostly type agnostic and architecture
indepedent. Prefer to use them if available.
* libc/include/math.h (fpclassify, isfinite, isinf, isnan,
isnormal): Use matching GCC builtin functions if built with
GCC 4.4 or later.
(signbit): Use matching GCC builtin functions if built with
GCC 4.0 or later.
(isgreater, isgreaterequal, isless, islessequal, islessgreater,
isunordered): Use matching GCC builtin functions if built with
GCC 2.97 or later.

__builtin_isinf_sign doesn't reflect the correct return value for NaN

Infinity returned from strtold is recognized as NaN by GCC builtin

While running tests on internal systems, we identified an issue in the
startup code for newlib on AArch32 systems with Multiprocessor
Extensions to the architecture.
The issue is we were configuring page table flags to be Inner
cacheable/Outer non-cacheable, while for at least architectures with
Multiprocessor Extension, we'd configure it to Inner/Outer write-back, no
write-allocate, and cacheable.
The attached patch fixes this, and no regression on arm-none-eabi
bare-metal tests.
Adopted suggestion given by Richard offline to avoid using jump.
libgloss/
* arm/cpu-init/rdimon-aem.S: Set TTBR0 to inner/outer
cacheable WB, and no allocate on WB for arch with multiprocessor
extension.

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:

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).

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

While C++11 was the first version of the standard to use C99 functionality,
TR1 (for C++03) also does, and G++ does not distinguish between C++98 and
C++03, or when TR1 is in use. Therefore, while not strictly correct for
"pure" C++98, enabling C99 for all C++ usage is the simplest solution (and
much better than always using -D_GNU_SOURCE as on Linux).

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
results though.

A user token can be up to 64K in size. Using 32K buffers for TOKEN_GROUPS

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.
(create_token): Ditto.

When running RTEMS paravirtualized in user space, the cli/sti instructions
can't be used. But I can't see why they are needed in either user or
supervisor state. Turning the use of them off for RTEMS.
This code is unmodified since the beginning of the repository, so I have
no insight into why it was done. I may even have been the one to add them.
Absolutely no idea except they aren't necessary.
