Move gdbsupport to the top level

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.

-/* Override operator new / operator new[], in order to internal_error

-   new-handler function instead (std::set_new_handler) because we want
-   to catch allocation errors from within global constructors too.
-
-   Skip overriding if building with -fsanitize=address though.
-   Address sanitizer wants to override operator new/delete too in
-   order to detect malloc+delete and new+free mismatches.  Our
-   versions would mask out ASan's, with the result of losing that
-   useful mismatch detection.
-
-   Note that C++ implementations could either have their throw
-   versions call the nothrow versions (libstdc++), or the other way
