Instead of allocating and registering the altstack in different
places, do it together to reduce code and improve readability.
When thread cache is enabled, storing altstack in rb_thread_t
is wasteful and we may reuse altstack in the same pthread.
This also lets us clearly allow use of xmalloc to allow GC to
recover from ENOMEM.
[ruby-core:85621] [Feature #14487]
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63213 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* vm_insnhelper.c (ec_stack_overflow): renamed from threadptr_stack_overflow
and also rb_ec_stack_overflow is from rb_threadptr_stack_overflow
because they accept `ec` instead of `th`.

to represent execution context [Feature #14038]
* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
There are many code using `th` to represent execution context
(such as cfp, VM stack and so on). To access `ec`, they need to
use `th->ec->...` (adding one indirection) so that we need to
replace them by passing `ec` instead of `th`.
* vm_core.h (GET_EC()): introduced to access current ec. Also
remove `ruby_current_thread` global variable.
* cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of
rb_context_t::thread_value.
* cont.c (ec_set_vm_stack): added to update vm_stack explicitly.
* cont.c (ec_switch): added to switch ec explicitly.
* cont.c (rb_fiber_close): added to terminate fibers explicitly.

* signal.c (check_stack_overflow): raise fatal when the last tag
is in danger zone.

each arrays, to shrink the size.

to rb_execution_context_t.

Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.
Some code used "status" instead of "state". To make them clear,
rename them to state.
We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

* thread.c (rbuy_kill): removed. This function is used
with SIGSEGV, SIGBUS, SIGKILL, SIGILL, SIGFPE and SIGSTOP
and these signals are affect immediately. So that `kill(2)'
is enough for them.
* signal.c (rb_f_kill): ditto.
* vm_core.h (rb_thread_t::interrupt_cond): removed because
only `ruby_kill()' uses this field.
* test/ruby/test_signal.rb: Without this patch sending SIGSTOP to own
process wait another interrupt even if another process sends SIGCONT.

* signal.c: disable handling signals to dump core, if installing
unreserved signals failed, not valgrind to hang on Mac OS.

thread.c and integrate with vm_stackoverflow.

close to the fault page, not same as sp page.

segfault a stack overflow when the fault address is between SP
and BP.

same rb_thread_t used for TH_PUSH_TAG, instead of JUMP_TAG with
the current thread global variable.

This allows us to reuse string objects used in symbols as well
as any string representations of signal names in source code.
* signal.c (sig_list): use fstring for hash key
* test/ruby/test_signal.rb (test_signal_list_dedupe_keys): added

signals SIGILL and SIGFPE, ont only SIGSEGV and SIGBUS.

seems that rb_bug_errno() is called in sigpipe() intentionally.

strncmp is unnecessary since the switch/case statement already
checks length of the string; so use memcmp.
This makes for a small reduction in binary size on 32-bit x86:

at stack overflow.
