Insert another class fhandler_socket_wsock between fhandler_socket
and fhandler_socket_inet/fhandler_socket_local.
Also, add a new method fhandler::is_wsock_socket to allow asking
for sockets in general (is_socket) vs. Winsock-based sockets
(is_wsock_socket).
This allows to develop a new handler_socket_unix class as derived
class from fhandler_socket without any trace of wsock code left
in fhandler_socket.
While this is basically a temporary measure at this time, it may
prove useful for later interoperability with the upcoming Windows 10
AF_UNIX implementation at one point.

* Rename DEV_TCP_MAJOR to DEV_SOCK_MAJOR
* Drop FH_TCP, FH_UDP, FH_ICMP in favor of single FH_INET
* Drop FH_UNIX, FH_STREAM, FH_DGRAM in favor of single FH_LOCAL

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.

- Move definition of windows to POSIX error mapping struct into
cygerrno.h
- Move declaration of winsock errno functions to cygerrno.h
- Input to error mapping functions is DWORD

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
preprocessing switch, actual call, per level/per optname
postprocessing switch for better readability as well as

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.

We're still using ~SO_REUSEADDR because SO_EXCLUSIVEADDRUSE wasn't
defined in Mingw. But it is in Mingw-w64, so fix it.
