Synchronize libiberty with gcc and add --no-recruse-limit option to tools that support name demangling.
This patch addresses the multitude of bug reports about resource exhaustion
in libiberty's name demangling code. It adds a limit to the amount of
recursion that is allowed, before an error is triggered. It also adds a
new demangling option to disable this limit. (The limit is enabled by
default).

enabled and reached, return with a failure result.

for a mangled string that is so long that there is not enough
stack space for the local arrays.
* cplus-dem.c (struct work): Add recursion_level field.
(demangle_nested_args): If the recursion limit is enabled and
reached, return with a failure result.
include * demangle.h (DMGL_RECURSE_LIMIT): Define.
