Cygwin: split out fhandler_socket into inet and local classes
First cut, still incomplete
* fhandler_socket is now base class for other socket classes
* fhandler_socket_inet handles AF_INET and AF_INET6 sockets
* fhandler_socket_local handles AF_LOCAL/AF_UNIX sockets
* finally get rid of fdsock by using set_socket_handle in accept4
* align file-related calls (fstat, fstatvfs, fchown, fchmod, facl)
to Linux.

Add fhandler_socket::set_socket_handle method, basically duplicating

Cygwin: improve O_TMPFILE handling
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.
* Redefine NSPERSEC to NS100PERSEC
* Define NSPERSEC as nanosecs per second
* Define USPERSEC as microsecs per second
* Use above constants throughout where appropriate
* Rename to_us to timespec_to_us and inline
* Rename it_bad to timespec_bad and inline
Rearrange setsockopt/getsockopt into per level/per optname
preprocessing switch, actual call, per level/per optname
postprocessing switch for better readability as well as
extensibility.
Cygwin: bindresvport: check correctness of address family
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.
Disable powf/log2?f/exp2?f optimization for single-precision Arm FPU
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.

cygwin: block devices: fix file offset after short writes
When reading/writing block devices, Cygwin emulates Linux, providing
a byte-exact file position, albeit the underlying device drivers don't.
Unfortunately this only worked correctly for reading. The raw_write
method failed to revalidate the buffer after the read-modify-write
cycle in case len is not a multiple of the sector length. This in
turn resulted in lseek reporting a wrong file pointer.
Also, fix a condition for invalidating the buffer after writing from
a remaining read buffer.
