Change SIGINT handler for extension languages only when target terminal is ours
I see a timeout in gdb.base/random-signal.exp,
Continuing.^M
PASS: gdb.base/random-signal.exp: continue
^CPython Exception <type 'exceptions.KeyboardInterrupt'> <type
exceptions.KeyboardInterrupt'>: ^M
FAIL: gdb.base/random-signal.exp: stop with control-c (timeout)
it can be reproduced by running random-signal.exp with native-gdbserver
in a loop, like this, and the fail will be shown in about 20 runs,
$ (set -e; while true; do make check RUNTESTFLAGS="--target_board=native-gdbserver random-signal.exp"; done)
In the test, the program is being single-stepped for software watchpoint,
and in each internal stop, python unwinder sniffer is used,

when GDB goes to python extension, or other language extension, the
SIGINT handler is changed, and is restored when GDB leaves extension
language. GDB only stays in extension language for a very short period
in this case, but if ctrl-c is pressed at that moment, python extension
will handle the SIGINT, and exceptions.KeyboardInterrupt is shown.
Language extension is used in GDB side rather than inferior side,
so GDB should only change SIGINT handler for extension language when
the terminal is ours (not inferior's). This is what this patch does.
With this patch applied, I run random-signal.exp in a loop for 18
hours, and no fail is shown.

[win32] cannot automatically find executable file [...] warning at GDB startup
The following change...
commit 43499ea30db2a866412c86952c7e1d7b158d806f
Date: Tue Nov 17 15:17:44 2015 +0000
Subject: [C++/mingw] windows-nat.c casts
... causes a small regression in GDB, where we get the following
warning at startup:
% gdb
C:\[...]\gdb.exe: warning: cannot automatically find executable file or library to read symbols.
Use "file" or "dll" command to load executable/libraries directly.
GNU gdb (GDB) 7.10.50.20151218-cvs (with AdaCore local changes)
[...]
(gdb)
The warning comes from _initialize_loadable which tries to dynamically
load some symbols from kernel32.dll and psapi.dll, and in particular:
hm = LoadLibrary ("psapi.dll");
if (hm)
{
GPA (hm, EnumProcessModules);
GPA (hm, GetModuleInformation);
GPA (hm, GetModuleFileNameEx);
}
The problem is that the new GPA macro assumes that the name of
the variable we use to point to the function, and the name of
its associated symbol are the same. This is mostly the case,
except for GetModuleFileNameEx, where the name is provided by
the GetModuleFileNameEx_name macro (defined differently depending
on whether we are on cygwin or not). As a result, the dynamic
resolution for GetModuleFileNameEx returns NULL, and we trip
the following check which leads to the warning:
if (!EnumProcessModules || !GetModuleInformation || !GetModuleFileNameEx)
{
[...]
warning(_("[...]"));
}
This patch fixes the problem by calling GetProcAddress directly,
rather than through the GPA macro, but in a way which hopefully
avoids the C++ compilation warning that the previous patch was
trying to get rid of.

* windows-nat.c (_initialize_loadable): Fix computing of
GetModuleFileNameEx.
