Queue, SizedQueue, and ConditionVariable internal implementation
should not be tied to using arrays. Implementation details can
change and I am working on a change to remove the dependency on
arrays (as others may attempt, too) by using ccan/list for the
waiter list.
* test/thread/test_cv.rb (test_dump): remove check for Array
* test/thread/test_queue.rb (test_dump): ditto

* parse.y (symbol, dsym, parser_set_number_literal, parser_yylex):
set state to END too not only ENDARG and after a literal, so
that a left brace after it should be a primary block bound to
the literal, which causes syntax error.

In string.c, replace hand-written argument count check by call to rb_scan_args.
This allows to use rb_funcallv once, rather than using rb_funcall twice.

The goal is to reduce rb_context_t and rb_fiber_t size
by removing the need to store the entire rb_thread_t in
there.

We can use existing RVALUE flags to avoid adding a 4-byte
integer to store a boolean flag. This integer cost us 8 bytes
due to default (lack of) struct packing on x86-64
* thread_sync.c (MUTEX_ALLOW_TRAP): define as FL_USER1
(struct rb_mutex_struct): remove allow_trap
(rb_mutex_lock): adjust for flag check

There are currently no benchmarks for Fiber performance, I
should've committed this years ago when [Feature #10341] was
implemented.

Instead of relying on a native condition variable and mutex for
every Ruby Mutex object, use a doubly linked-list to implement a
waiter queue in the Mutex. The immediate benefit of this is
reducing the size of every Mutex object, as some projects have
many objects requiring synchronization.
In the future, this technique using a linked-list and on-stack
list node (struct mutex_waiter) should allow us to easily
transition to M:N threading model, as we can avoid the native
thread dependency to implement Mutex.
We already do something similar for autoload in variable.c,
and this was inspired by the Linux kernel wait queue (as
ccan/list is inspired by the Linux kernel linked-list).
Finaly, there are big performance improvements for Mutex
benchmarks, especially in contended cases:

* For easier modifications of ruby/spec by MRI developers.
* .gitignore: track changes under spec.
* spec/mspec, spec/rubyspec: add in-tree mspec and ruby/spec.
These files can therefore be updated like any other file in MRI.
Instructions are provided in spec/README.
[Feature #13156] [ruby-core:79246]

The current range based current values of:
TIME_QUANTUM_USEC=100000
RUBY_THREAD_PRIORITY_MAX=3
RUBY_THREAD_PRIORITY_MIN=-3
Gives a range of 12500..800000, plenty enough for a 32-bit
integer. Clamping this also reduces potential implementation
bugs between 32-bit and 64-bit platforms.
I may consider a further reduction to uint16_t in the future
for M:N threading, but some users may want slightly larger
time quantums.
* vm_core.h (rb_thread_t): use 32-bit running_time_us

Somebody may pass 1030 (the value of F_DUPFD_CLOEXEC) to IO#fcntl
because they copied code from somewhere else. Ensure we know
about FDs created that way.
* io.c (do_fcntl): update max FD for F_DUPFD_CLOEXEC, too
