winsock.
* fhandler.cc (fhandler_base::set_inheritance): Make debugging output more
verbose.
* fhandler_socket.cc (fhandler_socket::fixup_after_fork): Force loading of
winsock32 if winsock2 not available.
* net.cc (set_socket_inheritance): Use DuplicateHandle in all cases to set
inheritance correctly.
(fdsock): Use winsock2_active macro to determine when to set socket
inheritance.  Remove fdtab resource locking since this function should already
be protected.
(cygwin_accept): Simplify logic.  Ensure that fdtab unlock is not called
inappropriately.
(cygwin_rcmd): Use fdtab locking.
(cygwin_rresvport): Ditto.
(cygwin_rexec): Ditto.
* select.cc (peek_socket): Set errno appropriately if winsock select fails.
* winsup.h: Declare check_pty_fds.
* syscalls.cc (check_pty_fds): Rename from check_ttys_fds.  Also check pty
master.
(setsid): Use check_pty_fds.
* dtable.cc (dtable::dec_console_fds): Add check on pty fds.
