For unsigned data types in the int family (tinyint, smallint, int, bigint),
truncate(x, d) now properly applies zeros when d < 0.

MCOL-2018 Fix array bounds issue
...
StringStore NULL check includes a check for _CpNuLl_ in the
StringStore. This is a case should never happen but we keep it just in
case.
Unfortunately this check was skipping 4*8 bytes instead of just 4 bytes.
This is definitely bad behaviour but it could cause an out-of-bounds read
based crash.

MCOL-1885 Fix libmysql error handling
...
If an error occurs in mysql_real_query() it fell through and tried to
get a result set anyway. This caused the MariaDB error message to be
forgotten and a generic one returned instead.
This fix returns the query error message and also uses the int error
code for generic errors instead of casting it to an unsigned int.

MCOL-1826 Fix race in FLOAT/DOUBLE to string
...
In the FLOAT/DOUBLE to string conversions a class global string was used
to store the result. Unfortunately it is possible for an instance of
this class to be used by multiple threads of PrimProc simultaneously.
This would cause a race and data corruption or more likely a crash.
This fix passes a string object from the caller to use instead.

MCOL-1810 Fix hang on low core count
...
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.
