This will be handled further in bug 5602

Previous behavior was confusing, and the code path hard to follow.
Rework, and clarify the established behavior in the appropriate man pages.

Bug 4514.

X11 implies Contain, and Contain is incompatible with NoHold as
the Extern step creation will race with the step launches.

Bug 5593.

scan-build complains about this possibly being used uninitialized with
pthread_join(), but on review the path it identifies as causing that
is impossible. Initialize this anyways in the hopes of surppressing that
warning.

This also randomizes the backup controller port numbers which
were not being handled here for some reason.

Change _build_path to return the xmalloc()'d string, and make sure
to free it where appropriate.

Add comment about how the processing of the PATH environment variable
here is backwards from convention.

Bug 5465.

MySQL permits up to 64-character database names, but Slurm was truncating
at 33-characters. If we exceed this limit, let the mysql_query fail and
give the admin a chance to sort it out, rather than truncating and then
failing to query against the un-truncated name later on.

While here correct the fatal() message.

Bug 5586.

Partial revert of 5b5228d0.

Calling init() on certain plugins is not safe. Remove the option,
documentation, and the test case for this.

See 19fc9d94 and the reversion in 61f04d67 as well.

Bug 5584

1. The cpu frequency set by the user is not exact with
   current kernels, but close. This changes the logic accordingly.
2. The original logic would cause the test to hang indefinitely
   if the submitted job never ends. This adds timeout checks
   on the job wait, plus adds a 1 minute time limit on the job.
3. Improve/simplify the parsing logic.

Bug 5584

Currently only valid nextstate states are down and resume/idle so the
node shouldn't be in a drain state after transitioning into either of
these states.

Bug 5544

This also clears up a potential race around ping_thread_cnt
as it was protected by ping_mutex in one location and shutdown_mutex
in another.
