The previous patch in this series creates a new directory service entry
specifically for obtaining the content process temp directory.
This patch converts everything else to reference that entry. It also sets
appropriate environment variables in the content processes so that system
APIs automatically pick up the directory. This is necessary for the crash
reporter to be able to call those APIs in exception handling contexts.

Modify the Mac sandbox to allow temporary files to be created in a
parent-specified subdirectory of NS_OS_TEMP_DIR. This is similar to the
Windows approach. The parent provides a UUID in a preference which is
used by the content process to form the subdirectory name.

Change the PContent protocol to support:
* Creating the template process.
* Forking new content processes from the template on the child side and cloning the actor on the parent side.
* Fallback to non-templated content process creation if no template-preallocated process is available.
