This reverts commit 18e55fc1e1ec20e8f3166e3059e76c885fc9f8f2.
fix [Bug #19704]
https://bugs.ruby-lang.org/issues/19704
This breaks compatibility for extension libraries. Such changes
need a discussion.

* Add rb_io_path and rb_io_open_descriptor.
* Use rb_io_open_descriptor to create PTY objects
* Rename FMODE_PREP -> FMODE_EXTERNAL and expose it
FMODE_PREP I believe refers to the concept of a "pre-prepared" file, but
FMODE_EXTERNAL is clearer about what the file descriptor represents and
aligns with language in the IO::Buffer module.
* Ensure that rb_io_open_descriptor closes the FD if it fails
If FMODE_EXTERNAL is not set, then it's guaranteed that Ruby will be
responsible for closing your file, eventually, if you pass it to
rb_io_open_descriptor, even if it raises an exception.
* Rename IS_EXTERNAL_FD -> RUBY_IO_EXTERNAL_P
* Expose `rb_io_closed_p`.
* Add `rb_io_mode` to get IO mode.

When one thread is closing a file descriptor whilst another thread is
concurrently reading it, we need to wait for the reading thread to be
done with it to prevent a potential EBADF (or, worse, file descriptor
reuse).
At the moment, that is done by keeping a list of threads still using the
file descriptor in io_close_fptr. It then continually calls
rb_thread_schedule() in fptr_finalize_flush until said list is empty.
That busy-looping seems to behave rather poorly on some OS's,
particulary FreeBSD. It can cause the TestIO#test_race_gets_and_close
test to fail (even with its very long 200 second timeout) because the
closing thread starves out the using thread.
To fix that, I introduce the concept of struct rb_io_close_wait_list; a
list of threads still using a file descriptor that we want to close. We
call `rb_notify_fd_close` to let the thread scheduler know we're closing
a FD, which fills the list with threads. Then, we call
rb_notify_fd_close_wait which will block the thread until all of the
still-using threads are done.
This is implemented with a condition variable sleep, so no busy-looping
is required.

Now, calling `rb_fork` directly breaks the PID cache and the timer
thread, so must use `rb_fork_ruby` or similar instead.

Let signal.c include "internal/error.h" explicitly to ensure that the
identifier rb_sys_fail_str in signal.c refers to the macro defined in
"internal/error.h" instead of the actual function.
That macro reads errno before evaluating its argument. Without this
change, the rb_signo2signm(sig) expression in the "trap" function in
signal.c will overwrite the errno before the actual rb_sys_fail_str
function reads the errno.

The socket extensions rubysocket.h pulls in the "private" include/gc.h,
which now depends on vm_core.h. vm_core.h pulls in id.h
when tool/update-deps generates the dependencies for the makefiles, it
generates the line for id.h to be based on VPATH, which is configured in
the extconf.rb for each of the extensions. By default VPATH does not
include the actual source directory of the current Ruby so the
dependency fails to resolve and linking fails.
We need to append the topdir and top_srcdir to VPATH to have the
dependancy picked up correctly (and I believe we need both of these to
cope with in-tree and out-of-tree builds).
I copied this from the approach taken in
https://github.com/ruby/ruby/blob/master/ext/objspace/extconf.rb#L3

[Feature #18885]
For now, the optimizations performed are:
- Run a major GC
- Compact the heap
- Promote all surviving objects to oldgen
Other optimizations may follow.

btest can't be used for testing RJIT because RJIT doesn't work on
miniruby. However, btest-ruby is not necessarily useful for testing RJIT
because both the runner could crash as well as the target.
TBH I'm not sure why we want to use RUNRUBY instead of BOOTSTRAPRUBY on
btest-ruby. However, to achieve what I want to do while keeping the
current behavior, I'm just introducing a new target.

We used to require MJIT is supported when YJIT is supported. However,
now that RJIT dropped some platforms that YJIT supports, it no longer
makes sense. We should be able to enable only YJIT, and vice versa.

This patch rewrites Ractor synchronization mechanism, send/receive
and take/yield.
* API
* Ractor::Selector is introduced for lightweight waiting
for many ractors.
* Data structure
* remove `struct rb_ractor_waiting_list` and use
`struct rb_ractor_queue takers_queue` to manage takers.
* remove `rb_ractor_t::yield_atexit` and use
`rb_ractor_t::sync::will_basket::type` to check the will.
* add `rb_ractor_basket::p.take` to represent a taking ractor.
* Synchronization protocol
* For the Ractor local GC, `take` can not make a copy object
directly so ask to generate the copy from the yielding ractor.
* The following steps shows what `r1.take` does on `r0`.
* step1: (r0) register `r0` into `r1`'s takers.
* step2: (r0) check `r1`'s status and wakeup r0 if `r1` is waiting
for yielding a value.
* step3: (r0) sleep until `r1` wakes up `r0`.
* The following steps shows what `Ractor.yield(v)` on `r1`.
* step1: (r1) check first takers of `r1` and if there is (`r0`),
make a copy object of `v` and pass it to `r0` and
wakes up `r0`.
* step2: (r1) if there is no taker ractors, sleep until
another ractor try to take.

If the previous instruction is not a leaf instruction, then the PC was
incremented before the instruction was ran (meaning the currently
executing instruction is actually the previous instruction), so we
should not increment the PC otherwise we will calculate the source
line for the next instruction.
This bug can be reproduced in the following script:
```
require "objspace"
ObjectSpace.trace_object_allocations_start
a =
1.0 / 0.0
p [ObjectSpace.allocation_sourceline(a), ObjectSpace.allocation_sourcefile(a)]
```
Which outputs: [4, "test.rb"]
This is incorrect because the object was allocated on line 10 and not
line 4. The behaviour is correct when we use a leaf instruction (e.g.
if we replaced `1.0 / 0.0` with `"hello"`), then the output is:
[10, "test.rb"].

Right now the attached object is stored as an instance variable
and all the call sites that either get or set it have to know how it's
stored.
It's preferable to hide this implementation detail behind accessors
so that it is easier to change how it's stored.

Rust 1.58.0 unfortunately doesn't provide facilities to control symbol
visibility/presence, but we care about controlling the list of
symbols exported from libruby-static.a and libruby.so.
This commit uses `ld -r` to make a single object out of rustc's
staticlib output, libyjit.a. This moves libyjit.a out of MAINLIBS and adds
libyjit.o into COMMONOBJS, which obviates the code for merging libyjit.a
into libruby-static.a. The odd appearance of libyjit.a in SOLIBS is also
gone.
To filter out symbols we do not want to export on ELF platforms, we use
objcopy after the partial link. On darwin, we supply a symbol list to
the linker which takes care of hiding unprefixed symbols.
