Dropping the 'LL' specifier leads to 32 bit truncation during timestamp
computation. Revert it. Exempt MSPERSEC which is used for 32 bit values.

Add fhandler_socket::socket method
Add fhandler_socket::set_socket_handle method, basically duplicating
what fdsock is doing. This is the first step in getting rid of fdsock.

Windows does not remove FILE_ATTRIBUTE_TEMPORARY by itself after a
file has been closed. It's just some attribute which can be set or
removed at will, despite its purpose.
Apparently there are tools out there which use FILE_ATTRIBUTE_TEMPORARY
accidentally or wrongly, even Microsoft's own tools are affected. In
the end, the filesystem is potentially full of files with this attribute
set.
Implement O_TMPFILE files with FILE_ATTRIBUTE_TEMPORARY and
FILE_ATTRIBUTE_HIDDEN set. This combination is pretty unlikely.

* Fix an incorrect condition to recognize AF_LOCAL sockets in
file-related functions (fchmod, fchown, fstat, fsttavfs, facl, link).
* Return successfully when called on unnamed or abstract AF_LOCAL sockets,
except link, just as on Linux.

The previous patch introduced a compiler warning on x86.
Given time_t is only 4 bytes on x86 we get a long vs. unsigned long
comparison in timeval_to_ms. Fix it by careful casting.

Rearrange setsockopt/getsockopt into per level/per optname

Workaround the problem that bind doesn't fail with EADDRINUSE
if a socket with the same local address is still in TIME_WAIT.
Use IP Helper functions to check if such a socket exist and don't
even try this port, if so.

Assuming the address parameter is non-NULL, the test in
cygwin_bindresvport_sa only tests if the address family is
supported at all, which is insufficient.
Check if the incoming address family matches the socket
address family and for being AF_INET in cygwin_bindresvport
since the latter doesn't support any other family.

New optimized powf, logf, log2f, expf and exp2f yield worse performance
on Arm targets with only single precision instructions because the
double precision arithmetic is then implemented via softfloat routines.
This patch uses the old implementation when double precision
instructions are not available on Arm targets.
Testing: Built newlib with GCC's rmprofile Arm multilibs and compared
before/after -> only the above functions are changed and calls to them
(name change from logf to __ieee754_logf and similar). Testing the
changed function on a panel of values yields the same result before the
original patches to improve them and after this one. Double checking the
performance by looping the same panel of values being tested on Arm
Cortex-M4 does show the performance regression is fixed.
This new function returns the name of the calling thread; works for both
cygthreads and pthreads. All calls to cygthread::name(/*void*/) replaced
by calls to mythreadname(/*void*/).
This patch fixes a syntax error in exit.c that was introduced during the
ANSI-fication of newlib. The patch fixes a compile-time issue that arises when
newlib is configured with the --enable-lite-exit feature.
While POSIX mandates that certain socket types shall be defined by the
inclusing of <netinet/in.h>, it also says that this header may also make
visible all <sys/socket.h> symbols. Glibc does this, and without out it,
some packages end up requiring an additional #include <sys/socket.h>.

POSIX does not mention the inclusion of <sys/time.h> in <sys/socket.h>
or <netinet/in.h>, nor is there anything in the latter two that would
require the former.
