replace stub function with real implementation;
(procfs_lwp_creation_handler): fix bug starting new child

"INFO PROCESSES" command; (close_procinfo_file): call new
function "delete_thread" to cleanup GDB's thread database;
(proc_init_failed): add new argument "kill", to control whether
process is killed (so this function can be shared by

exit from an attached process, and cleanup procinfo handles
when the process exits; (procfs_resume, procfs_wait): cleanup
after a thread when it exits; (do_attach, do_detach): handle
