to avoid GC problem in very early stage.
(RUBY_GC_STRESS causes GC in such stage.)
* variable.c (rb_gc_mark_global_tbl): rb_global_tbl may be 0 in
very early stage.
* thread.c (thread_cleanup_func) [IA64]: clear register stack position.
(thread_start_func_2) [IA64]: record the beginning of register
stack using extra argument.
(rb_gc_save_machine_context) [IA64]: record the end of register
stack.
* gc.c [IA64] (SET_STACK_END): record the end of register stack.
(garbage_collect) [IA64]: use recorded register stack area for
GC marking.
(yarv_machine_stack_mark) [IA64]: GC mark from the register stack
area.
* yarvcore.c [IA64] (rb_gc_register_stack_start): defined.
(Init_VM): store th->self on stack to fix GC problem.
(Init_yarv) [IA64]: initialize the beginning of register stack.
* yarvcore.h (struct rb_thread_struct) [IA64]: new members for
register stack area.
* thread_pthread.ci (thread_start_func_1) [IA64]: call
thread_start_func_2 with the end of register stack.
* cont.c (struct rb_context_struct) [IA64]: new members for register
stack area.
(cont_mark) [IA64]: GC mark from register stack area.
(cont_free) [IA64]: free saved register stack.
(cont_save_machine_stack) [IA64]: record the position and contents
of the register stack.
(cont_capture): store cont->self on stack to fix GC problem.
(cont_restore_1) [IA64]: restore the register stack.
[IA64] (register_stack_extend): new function.
(cont_restore_0) [IA64]: call register_stack_extend instead of
cont_restore_1.

* thread.c (BLOCKING_REGION): restore previous UBF.
* thread.c (rb_thread_blocking_region): default UBF to interrupt
in system dependent way by RB_UBF_DFL.

+ ubf_handle() on Win32
+ none on cygwin

move cleanup function to thread_start_func_2().
* thread.c, thread_pthread.ci, thread_win32.ci:
add more destruct functions.
(native_thread_destroy() and native_mutex_destroy())
* thread_pthread.ci, thread_pthread.h: make native_mutex_* functions
(check error, etc), it's not macro any more.
* thread_win32.ci (thread_start_func_1): store some values before
running thread (to release these after running thread).
* thread_win32.ci (native_thread_create): fix spaces.

moving definitions place, add/remove prototypes, deleting
unused variables and removing yarv.h.
This commit doesn't change any behavior of ruby/vm.
* yarv.h, common.mk: remove yarv.h (contents are moved to yarvcore.h).
* error.c, eval_intern.h: include yarvcore.h instead yarv.h
* rename some functions:
* debug.[ch]: debug_*() -> ruby_debug_*()
* iseq.c: iseq_*() -> rb_iseq_*(), ruby_iseq_disasm()
* iseq.c: node_name() -> ruby_node_name()
* vm.c: yarv_check_redefinition_opt_method() ->
rb_vm_check_redefinition_opt_method()
* some refactoring with checking -Wall.
* array.c: remove rb_ary_ptr() (unused) and remove unused
local variables.
* object.c: add a prototype of rb_mod_module_exec().
* eval_intern.h (ruby_cref): set it inline.
* eval_load.c (rb_load), yarvcore.c: yarv_load() -> rb_load_internal().
* parse.y: add a prototype of rb_parse_in_eval() (in eval.c).
* process.c: add a prototype of rb_thread_stop_timer_thread() (in thread.c).
* thread.c: remove raw_gets() function (unused) and fix some format
mismatch (format mismatchs have remained yet. this is todo).
* thread.c (rb_thread_wait_fd_rw): fix typo on label name.
* thread_pthread.ci: comment out codes with USE_THREAD_CACHE.
* vm.c (rb_svar, rb_backref_get, rb_backref_get,
rb_lastline_get, rb_lastline_set) : moved from yarvcore.c.
* vm.c (yarv_init_redefined_flag): add a prototype and rename
yarv_opt_method_table to vm_opt_method_table.
* vm.c (rb_thread_eval): moved from yarvcore.c.
* yarvcore.c: remove unused global variables and fix to use nsdr().

rb_thread_start_timer_thread()): added.
* thread_pthread.ci: add a native_thread_join() and move
rb_thread_reset_timer_thread() definition to thread.c.
* thread_win32.ci: ditto
* process.c: fix before_exec(), after_exec() to stop timer thread
(and restart timer thread if exec failed). and fix to reset
timer thread information when forked child process starts
(to fix [ruby-core:09822]).
