Use c_string for default_pager_filename_t to define a new default_pager_paging_storage RPC.
This brings us a bit closer to having all types' msgt_size representable
with a single byte. We will be able to avoid mach_msg_type_long_t
entirely for x86_64 since mach_msg_type_t can represent long types using
a separate field.
