Fix the MS-Windows build

* src/thread.h [WINDOWSNT]: Include sys/socket.h.

* src/sysselect.h: Don't define fd_set and FD_* macros for
MS-Windows here.
* src/w32.h: Define them here.

* src/process.h (sys_select): Declare prototype.

* src/sysdep.c:
* src/process.c:
* src/filelock.c:
* src/emacs.c:
* src/callproc.c: Move inclusion of sys/select.h after lisp.h.
* nt/inc/socket.h: Include w32.h instead of sysselect.h
