The macro TEST_VERIFY_EXIT is used several times on
sunrpc/tst-udp-timeout to exit the test if a condition evaluates to
false. The side effect is that the code to terminate the RPC server
process is not executed when the program calls exit, so that
sub-process stays alive.
This commit registers a clean up function with atexit to kill the
server process before exiting the main program.

As the sort was removed, there's no need to keep a separate map of
links. Instead, when relocating objects iterate over l_initfini
directly.
This allows us to remove the loop copying l_initfini elements into
map. We still need a loop to identify the first and last elements that
need relocation.
Tested by running the testsuite on x86_64.
l_initfini is already sorted by dependency in _dl_map_object_deps(),
so avoid sorting again in dl_open_worker().
Tested by running the testsuite on x86_64.
There are two fixes that are needed to be able to dlopen filter
objects. First _dl_map_object_deps cannot assume that map will be at
the beginning of l_searchlist.r_list[], as filtees are inserted before
map. Secondly dl_open_worker needs to ensure that filtees get
relocated.
In _dl_map_object_deps:
* avoiding removing relocation dependencies of map by setting
l_reserved to 0 and otherwise processing the rest of the search
list.
* ensure that map remains at the beginning of l_initfini - the list
of things that need initialisation (and destruction). Do this by
splitting the copy up. This may not be required, but matches the
initialization order without dlopen.
Modify dl_open_worker to relocate the objects in new->l_inifini.
new->l_initfini is constructed in _dl_map_object_deps, and lists the
objects that need initialization and destruction. Originally the list
of objects in new->l_next are relocated. All of these objects should
also be included in new->l_initfini (both lists are populated with
dependencies in _dl_map_object_deps). We can't use new->l_prev to pick
up filtees, as during a recursive dlopen from an interposed malloc
call, l->prev can contain objects that are not ready for relocation.
Add tests to verify that symbols resolve to the filtee implementation
when auxiliary and filter objects are used, both as a normal link and
when dlopen'd.
Tested by running the testsuite on x86_64.
Linux 5.5 renames RWF_WRITE_LIFE_NOT_SET to RWH_WRITE_LIFE_NOT_SET,
with the old name kept as an alias. This patch makes the
corresponding change in glibc.
Tested for x86_64.
The comment "isn't" contained a non-ascii character which leads to
an error if compiled with -finput-charset=ascii:

The code started out with bits form resolv/resolv_conf.c, but it
was enhanced to deal with directories and FIFOs in a more predictable
manner. A test case is included as well.
This will be used to implement the /etc/resolv.conf change detection.
This currently lives in a header file only. Once there are multiple
users, the implementations should be moved into C files.
The missing dependencies result in failures like this if make check
is invoked with sufficient parallelism for the debug subdirectory:

900778283a ("htl: make pthread_spin_lock really spin") made
pthread_spin_lock really spin and not block, but the current users of
__pthread_spin_lock were assuming that it blocks, i.e. they use it as a
lightweight mutex fitting in just one int.
__pthread_spin_wait provides that support back.
This should be unconditionally set to match the common implementation,
and fixes multiple test failures related to sprintf.

Now that binutils-gdb has gdbserver at top level, an extra
--disable-gdbserver configure option is needed when configuring
binutils from a git checkout to avoid it also building gdbserver
unnecessarily (although fairly harmlessly). This patch updates the
options used in build-many-glibcs.py accordingly (although this might
end up not being needed depending on what happens regarding whether
gdbserver gets built for host != target).
Tested with a build-many-glibcs.py compilers build for
aarch64-linux-gnu using binutils-gdb master.

They were not getting used anyway.
Also do not make libsupport use them, it would make tests using it have
to be made to link against libmachuser for gsync_wait.
