* vm.c (th_init): preallocate alternative stack.
NoMemoryError is better than rb_bug, of course.
Patch by Eric Wong. [ruby-core:38572][ruby-core:38594].
* signal.c (rb_register_sigaltstack): ditto.
* vm_core.h: moved ALT_STACK_SIZE definition from signal.c.
* vm.c (thread_free): use xfree() instead of free().
