libiberty has been merged

[DJ Delorie]

The "src" libiberty (and a few files in include/ that go with it) now
matches gcc's libiberty (the master).  Please report libiberty bugs to
the appropriate gcc mailing list (probably gcc-bugs@gcc.gnu.org).

In the future, please feel free to merge any patches you may need from
the gcc libiberty to the src libiberty, although I will attempt to
keep them in sync myself (hopefully via automation).  If you check
approved patches into the gcc libiberty, please also check them into
the src libiberty.

Thanks,
DJ
