When doing out-of-source builds I often end up wanting to use gdb from
inside a build directory.
Currently if I do that the `.gdbinit` in the ruby source directory is
not read.
Attempting to manually load the `.gdbinit` from the Ruby source
directory errors because of hard coded file-paths that assume we're
running gdb from inside the source tree.
Adding the `-s` flag to the `source` command when loading relative files
signals to gdb to search in the source search path for the required
file, rather than just the current directory.
This allows me to use a custom `.gdbinit` from my build directory that
sets the correct source directory and then loads the Ruby `.gdbinit`.
```
dir ../src
source ../src/.gdbinit
```
After a0f12a0258 NODE_GASGN and
NODE_GVAR hold same value on both nd_vid and nd_entry.
This commit stops setting value to nd_entry and makes to use only
nd_vid.
Other changes are needed to bring .gdbinit up-to-date with current ruby.
It looks like lldb is the preferred approach now, and that config *is*
being kept up-to-date. Still, this might be helpful to someone?
Now that RUBY_FL_TAINT is recycled to become new RUBY_FL_SHAREABLE.
Setting/clearing this flag from extension libraries break Ractor.
Especially problematic one is OBJ_INFECT, which would make non-shareable
objects travel across Ractor boundaries.
Such operations should just be prohibited.
RHASH_ARRAY_{LEN,BOUND}_{MASK,SHIFT} have been renamed to
RHASH_AR_TABLE_{SIZE,BOUND}_{MASK,SHIFT}.

* hash.c, internal.h: support theap for small Hash.
Introduce RHASH_ARRAY (li_table) besides st_table and small Hash
(<=8 entries) are managed by an array data structure.
This array data can be managed by theap.
If st_table is needed, then converting array data to st_table data.
For st_table using code, we prepare "stlike" APIs which accepts hash value
and are very similar to st_ APIs.

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.

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.
