When r241373 was merged, one file appears to have been missed from the

2013-03-28T09:03:15+00:00

commit.  Merge it:
        Remove undefined behavior from sranddev() and
        srandomdev(). This doesn't actually work
        with any modern C compiler:

        In particular, both clang and modern gcc
        verisons silently elide any xor operation
        with 'junk'.

No mergeinfo changes with this commit as r241475 already updated the
mergeinfo.

MFC r211706:

On shared object unload, in __cxa_finalize, call and clear all installed
atexit and __cxa_atexit handlers that are either installed by unloaded
dso, or points to the functions provided by the dso.

Use _rtld_addr_phdr to locate segment information from the address of
private variable belonging to the dso, supplied by crtstuff.c. Provide
utility function __elf_phdr_match_addr to do the match of address against
dso executable segment.

Call back into libthr from __cxa_finalize using weak
__pthread_cxa_finalize symbol to remove any atfork handler which
function points into unloaded object.

The rtld needs private __pthread_cxa_finalize symbol to not require
resolution of the weak undefined symbol at initialization time. This
cannot work, since rtld is relocated before sym_zero is set up.

MFC r211894:
Do not call __pthread_cxa_finalize with invalid struct dl_phdr_info.
