os: Add -displayfd option.cygwin-patches-for-1.9

This option specifies a file descriptor in the launching process. X
will scan for an available display number and write that number back to
the launching process, at the same time as SIGUSR1 generation. This
means display managers don't need to guess at available display numbers.
As a consequence, if X fails to start when using -displayfd, it's not
because the display was in use, so there's no point in retrying the X
launch on a higher display number.

Update for current X server
Fix null DISPLAY crash when stderr is closed
Rearrange init order to avoid null DISPLAY crash and correctly use
DISPLAY in default logfile name when logfile isn't specified on command line
Don't put '\'n on end of DISPLAY so internal XWin uses work correctly
Do a bit more logging about what we are trying to do
