Subject: [PATCH] Fix gp_file allocations to use thread_safe_memory.

The gpmisc.c does allocations for gp_file objects and buffers used by
gp_fprintf, as well as gp_validate_path_len. The helgrind run with
-dBGPrint -dNumRenderingThreads=4 and PCL input showed up the gp_fprintf
problem since the clist rendering would call gp_fprintf using the same
allocator (PCL's chunk allocator which is non_gc_memory). The chunk
allocator is intentionally not thread safe (for performance).
