Spurious wakeup is unavoidable with MJIT; and any real
code must be able to deal with spurious wakeup anyways.

* doc/*: Move entry to default gems category from standard library.
* lib/shell/*: Added `Shell::VERSION` and re-used it with @RELEASE_VERSION.
* test/shell/test_command_processor.rb: added missing require for test library.
* tool/sync_default_gems.rb: Support shell library. We need to ignore shellwords.rb when
syncing shell* files.

No point in having a long-lived cbuf in "struct gzfile"
since GZFILE_CBUF_CAPA is smaller than RSTRING_EMBED_LEN_MAX
(even on 32-bit). We can also have rb_econv_convert write
directly to the return value instead of an intermediate buffer.
This brings "struct gzfile" from 264 to 256 bytes on 64-bit
systems to avoid taking an additional cache line.

This commit fixes a build error on systems that have
`malloc_usable_size` but also enable jemalloc via `--with-jemalloc`.
For example, Ubuntu Precise defines `malloc_usable_size` in malloc.h, so
gc.c will include malloc.h. This definition conflicts with jemalloc's
definition, so the following error occurs:
```
compiling gc.c
compiling hash.c
In file included from gc.c:50:0:
/usr/include/malloc.h:152:15: error: conflicting types for 'malloc_usable_size'
/usr/include/jemalloc/jemalloc.h:45:8: note: previous declaration of 'malloc_usable_size' was here
cc1: warning: unrecognized command line option "-Wno-self-assign" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-constant-logical-operand" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-parentheses-equality" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-tautological-compare" [enabled by default]
```
Since jemalloc always defines `malloc_usable_size`, this patch just
includes the jemalloc header instead of malloc.h if it's available.

This optimization was reverted on r63863, but this commit resurrects the
optimization to skip some sp motions on JIT execution.
tool/ruby_vm/views/_mjit_compile_insn_body.erb: ditto
tool/ruby_vm/views/_mjit_compile_insn.erb: ditto
insns.def: resurrect handles_frame as handles_stack, which was deleted
on r63763.
tool/ruby_vm/models/bare_instructions.rb: ditto
vm_insnhelper.c: prevent moving sp outside insns.def to allow modifying
it by JIT.

I suspect CI test machine was overloaded at the time,
or swapping at the time due to parallel build with mjit.

There's actually no need to close the pipes used by the
sleepy timer thread before forking, only to stop the timer
thread itself.
Instead, we only close the parent pipes in the child process,
either via close-on-exec flag or when reinitializing the timer
thread.
This change will be necessary when we allow
rb_wait_for_single_fd and rb_thread_fd_select to wait on the
timer_thread_pipe.normal[0] directly and eliminate timer thread.
I don't anticipate compatibility problems with this change
alone.

Improve branch misses on frozen object predicate checks negatively
affecting performance of most setters as most objects are not frozen.
