Subject: [PATCH 2/6] 7.8-windows-nat-cygwin
Remaining parts of 7.8-windows-nat-cygwin.patch not yet upstream.
Signal changes:
* Replace have_saved_context with signal_thread_id throughout, and store the
thread id in it
* In thread_rec(), only use the signal saved context if we are retrieving the
context for the correct thread.
* Clear ContextFlags in the signal saved context so we never attempt to restore
it to the inferior
Since the signal context is the context which will be restored after any signal
handler has been run, to resume to it skips over the actual signal delivery.
(Unfortunately, this isn't quite right. If GDB decides it needs to single-step
after continuing by setting FLAG_TRACE_BIT, we must alter the inferior state. So
we potentially need to have both the signal saved context, and the actual
context for the thread. Which is not a straightforward change to make.)
Unrelated changes:
* An unclear change for detecting if it's an unexpected Cygwin message. Just
checking for a leading 'cYg' should be enough?
* Cast DWORD thread_id to int before returning it from get_windows_event.
(I don't think this is needed. If DWORD->int is a narrowing conversion, we
have other problems...)
* In one place, clarify that thread_rec()'s second parameter is a bool flag.
(This should be done everywhere, or not)

Subject: [PATCH 02/10] Only ignore expected Cygwin OutputDebugStrings()
Rather than ignoring all debug strings starting with 'cYg', just ignore
the expected ones:
- 'cYgSiGw00f' informs the debugger of a Cygwin signal in the debuggee
- 'cYgstd' invites the debugger to alter stdin/out/err fds in the debuggee
- 'cYgFFFFFFFFFF' invites the debugger to activate strace output from the debugee
Any other debug string starting 'cYg' is unexpected, and reported
verbatim.

Subject: [PATCH 3/6] Better handling for realpath() failures in
windows_make_so() on Cygwin
Fix a memory leak which would occur in the case when the result of realpath() is
greater than or equal to SO_NAME_MAX_PATH_SIZE.
Distinguish between realpath() failing (returning NULL), and returning a path
longer than SO_NAME_MAX_PATH_SIZE
Warn rather than stopping with an error in those cases.
Original patch from Tim Chick. Memory leak fix by Corinna Vinschen.

Subject: [PATCH 5/6] Drop special way of getting inferior context after a
Cygwin signal
Simplify Cygwin signal handling by dropping the special way of getting
inferior context after a Cygwin signal.
I think the reason this existed was because previously we were not able
to unwind through the alternate stack used by _sigfe frames, so without
the hint of the "user" code IP, the backtrace from a signal was
unusable.
Now we can unwind through _sigfe frames, drop all this complexity.
(Restoring this specially obtained context to the inferior (as the code
currently does) skips over the actual signal delivery and handling.
Cygwin has carried for a long time a patch which clears the ContextFlags
in the signal context, so we never attempt to restore it to the
inferior, but that interfers with gdb's ability to modify that context
e.g. if it decides it wants to turn on FLAG_TRACE_BIT)
v2:
Update use of DEBUG_EVENTS, changed in 4ef367bf
v3:
Update for windows_per_inferior struct

Subject: [PATCH 6/7] Use cygwin pgid if inferior is a cygwin process
I have noticed that cygwin gdb has a problem with the terrminal process
group on the inferior. e.g.:
1) Install coreutils-debuginfo package.
2) Run "gdb cat".
3) Enter "start" in gdb.
4) Enter "cont" in gdb.
This results in:
/usr/bin/cat: -: Input/output error
Cygwin gdb uses CreateProcessW() to execute debugging process, rather
than exec(), so gdb has the Windows (rather than cygwin) PID.
If the inferior is a cygwin process, use the cygwin pid. However, if
the inferior is a non-cygwin process, tcsetpgrp() is not meaningful and
there is no appropriate pgid to set.
