resolv_test: Fix racy exit check, remove mutexes, and reduce output
Instead of polling nleft[i] (without appropriate memory barriers!) and
using sleep() to detect the exit just call pthread_join() on all threads.
Also replace the use of a mutex that guarding the increments with atomic
fetch_add. This should reduce the runtime of this test on SMP systems.
Finally, remove all the debug printfs unless DEBUG_OUTPUT is set in
the environment.
Test Plan: still fails sometimes on qemu (but maybe less often?)

libc: tests: add some tests for cpuset(2)
The cpuset(2) tests should be run as root (require.user properly set) with
>= 3 cpus for maximum coverage. All tests that want to modify the cpuset
don't assume any particular cpu layout (i.e. the first cpu may not be 0, the
last may not be first + count) and the following scenarios are tested:
1.) newset: basic execute cpuset() to grab a new cpuset, make sure the
assigned cpuset then has a different ID.
2.) transient: create a new cpuset then assign the process its original
cpuset, ensuring that the one we created is now gone.
3.) deadlk: test assigning an anonymous mask, then resetting the process
base affinity with 1-cpu overlap w.r.t. the anonymous mask and with
0-cpu overlap w.r.t. the anonymous mask.
4.) jail_attach_newbase: process attaches to a jail with its own
cpuset+mask (e.g. cpuset -c -l 1,2 jail -c path=/ command=/bin/sh)
5.) jail_attach_newbase_plain: process attaches to a jail with its own
cpuset (e.g. cpuset -c jail -c path=/ command=/bin/sh)
6.) jail_attach_prevbase: process attaches to a jail with the containing
jail's root cpuset (e.g. jail -c path=/ command=/bin/sh)
7.) jail_attach_plain: process attaches to a jail with the containing jail's
root cpuset+mask.
8.) badparent: creates a new cpuset and modifies the anonymous thread mask,
then setid's back to the original and checks that cpuset_getid() returns
the expected set.

libc tests: dynthr_mod: fix some WARNS issues
This is being addressed as part of a side-patch I'm working on that builds
all the things with WARNS=6, instead of relying on it being supplied in just
shallow parts of the build with higher-level Makefile.inc.
Provide a prototype for mod_main and annotate the thread function argument
as unused.

Various fixes to the load() function.
- Use getline() instead of fgetln(). This ensures the returned string
is always null-terminated without losing the last character if the
last line in a file doesn't have a newline. Also, while fgetln says
the returned buffer can be modified, that doesn't actually seem safe
as the current implementation means you are modifying stdio's
internal buffer.
- Remove a spurious if before an ATF_REQUIRE that was clearly supposed
to be non-optional.
- Remove a pointless compare of 'ptr' against '\0' (really NULL) that
duplicated the middle condition in the for().
- Once a comment is found, skip the rest of the line, not just the
current word.
