This patch moves the gdbsupport directory to the top level. This is the next step in the ongoing project to move gdbserver to the top level. The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport". This patch then adds a build system to gdbsupport and wires it into the top level. Then it changes gdb to use the top-level build. gdbserver, on the other hand, is not yet changed. It still does its own build of gdbsupport.

/* The underlying idea is that when a Windows program is terminated by
|
|
a fatal exception, its exit code is the value of that exception, as
|
|
defined by the various EXCEPTION_* symbols in the Windows API
|
|
headers. We thus emulate WTERMSIG etc. by translating the fatal
|
|
exception codes to more-or-less equivalent Posix signals.
|
|
|
|
The translation below is not perfect, because a program could
|
|
legitimately exit normally with a status whose value happens to
|
|
have the high bits set, but that's extremely rare, to say the
|
|
least, and it is deemed such a negligibly small probability of
|
|
false positives is justified by the utility of reporting the
|
|
terminating signal in the "normal" cases. */
