Make piping to subprocesses more robust on MS-Windows
* src/w32.c (sys_write): Don't write to a pipe more stuff than its
buffer can hold. Don't return -1 if something has been written to
the pipe. Zero out 'errno' before calling '_write', to avoid
returning a stale value. (Bug#22344)
* src/w32proc.c (syms_of_ntproc) <w32-pipe-buffer-size>: New variable.
* src/w32.c (pipe2): Use it to request a user-defined size for the
pipe being created.
* etc/NEWS: Mention 'w32-pipe-buffer-size'.
* doc/emacs/msdos.texi (Windows Processes): Document
'w32-pipe-buffer-size'.
