Cygwin: signal: Implement fake stop/cont for non-cygwin processHEADgithub/mastergithub/mainmastermain

Currently, the following command in bash cannot make `cat | cmd`
foreground correctly, and also cannot be terminated by Ctrl-C.

  $ cat |cmd &
  $ fg
  $ (Ctrl-C)

This is because, bash does not recognize the process `cmd` as stopped
by SIGTTIN, and does not send SIGCONT not only to `cmd` but also to
`cat`.

To solve this problem, this patch implements fake stop/cont for non-
cygwin process such as `cmd`. Even with this patch, the process `cmd`
does not enter into stopped state because non-cygwin process itself
does not handle cygwin signal, but the stub process for `cmd` enters
into stopped state instead by SIGTTIN.
