* gdb_proc_service.h (paddr_t): Delete typedef.

	* proc-service.c (ps_addr_to_core_addr, core_addr_to_ps_addr): New.
	(ps_xfer_memory): Take a psaddr_t.  Use ps_addr_to_core_addr.
	(ps_pglobal_lookup): Take a psaddr_t *.  Use core_addr_to_ps_addr.
	(ps_pdread, ps_pdwrite, ps_ptread, ps_ptwrite): Take a psaddr_t.
	* sol-thread.c (gdb_ps_addr_t): Use psaddr_t instead of paddr_t.
	* Makefile.in (proc-service.o): Update.
