Fixed pragmas that disables compilation checks.
DDLProc now returns an error if it couldn't cwd.
Use either auto_ptr or unique_ptr depending on GCC version.
Anything that links against joblist will spin up a threadpool upon
startup. This includes the tools setConfig/getConfig. It is possible on
a low core count machine or low CPU speed that the signal to the prune
thread to shutdown is sent before the thread has completed startup when
these quick-running tools are used.
This fix adds a mutex so that spin up and shutdown can't happen at the
same time as well as a stop watch in case we are shutting down when
either the thread is running or we haven't fully started.

When a thread has been idle for 10 minutes and we have too many threads
in the threadpool the thread will be pruned. This is done by the
thread's main function just returning. Unfortunately this does not free
up the memory, the thread either needs to be joined or detatched.
We cannot use detached threads since there are mutexes and conditional
variables between the main thread and the threadpool threads. If the
main thread finishes before the threadpool threads (as would happen in
cpimport) then crashes occur. The parent needs to wait on the child
threads which is the whole point in joining.
So this fix spawns a new thread which every minute will check the list
of threads to be joined due to timeout and join them.
We have had to use an adapted version of boost::thread_group so that we
can join a single thread based off its thread ID.
In addition with have modified PriorityThreadPool to use detached
threads since this does not need to signal the child threads at the end.
PriorityThreadPool didn't have very good error handling. If something
failed it would just ignore whatever was being processed. This could
lead to a query continuing without retreiving all of the required data.
This patch adds error handling, sending a message back to the client
and a log message. It also destroys and recreates the pool thread.
Ubuntu 18.04 uses GCC 7.3 which is a little stricter than before.
Fixes a few errors due to implicit includes that are no longer implicit
and a ton of warnings about the implied alignment of code in
utils/common/any.hpp
Remove generated Makefiles
Update Makefile.am to specify RPATH as a subdirectory of --prefix
Remove configure artifacts such as config.log, config.h, etc
Remove unneeded backup files (files ending in tilde ~)
