* src/lisp.h (PVECHEADERSIZE): New macro. (XSETPVECTYPESIZE): Use it. * src/search.c (syms_of_search): No need to initialize or staticpro last_thing_searched or saved_last_thing_searched, as the thread code arranges for initialization and GC. * src/thread.c (main_thread): Initialize statically. (Fmake_mutex, Fmake_condition_variable, Fmake_thread): Use ALLOCATE_ZEROED_PSEUDOVECTOR rather than zeroing by hand. (mark_one_thread): No need to mark Lisp_Object members. (init_main_thread, init_threads_once): Remove. All uses removed.
