Introduce GS_THREADSAFE define and modify printing calls.

Lots of debugging/error information is printed using eprintf and
dlprintf etc. These functions do not take a gs_memory_t * and are
not safe for use within code that runs under multiple instances
created by gsapi.

Introduce new versions (dmprintf, dmlprintf etc) that DO take a
gs_memory_ *, and move as much of ghostscript/ghostpdl's usage
over to these as possible. I have not touched the contrib directory,
and some locations in the code do not easily have a gs_memory_t
to hand, so I have left them be.

If the GS_THREADSAFE define is made during building, then the
functions that don't take an explicit memory handle are #defined
away to nothing.

If the GS_THREADSAFE define is made, we disable the gsapi check that
checks for a single init.
