* procfs.c (procfs_thread_alive procfs_stop): Make static. 

* (procfs_pid_to_str):  New routine to print out thread id's in an
	intelligible manner.
	* sol-thread.c (sol_thread_fetch_registers):  Re-order manner in
	which supply_register is called to fix bug with writing writing
	individual regs.
	* config/sparc/tm-sun4sol2.h:  Define default for
	target_pid_to_str in case host lacks libthread_db.
