[[Bug #20418]](https://bugs.ruby-lang.org/issues/20418)
Ruby IO#read preserves the encoding on partial read, but change it when
reading the whole IO
from commit https://github.com/ruby/ruby/commit/0ca7036682da:
> * io.c (read_all): should associate default external encoding.
> * io.c (io_read): should NOT associate default external encoding.

File.birthtime has existed since Ruby 2.2, and pathname requires Ruby
>= 2.7.0, so the method will always be there.

If `posix_openpt` is available, also `ptsname` should be available.
|
|
89cfc152071 removed the definition of these functions.
|
|
Although glibc `ptsname_r` man page mentions Tru64 and HP-UX, this
function appears to be declared obsolete on both.

- start a new session
- obtain the new controlling terminal
- drop privileges
- finally, `exec`

This reverts commit 054a412d540e7ed2de63d68da753f585ea6616c3.
SIGCHLD `waidpid`, `waitpid_lock` and related code, have been removed
at ruby/ruby#7527.

No parser semantic value types are `VALUE` then no need to
use imemo for managing semantic value stack anymore.

clause duplication
This commit simplifies warnings for hash keys duplication and when clause duplication,
based on the discussion of https://bugs.ruby-lang.org/issues/20331.
Warnings are reported only when strings are same to ohters.

We use the following site for that now:
* https://tools.ietf.org/ or http
* https://datatracker.ietf.org or http
Today, IETF said the official site of RFC is www.rfc-editor.org.
FYI: https://authors.ietf.org/en/references-in-rfcxml
I replaced them to www.rfc-editor.org.

If an exception is raised the FBuffer is leaked.
For example, the following script leaks memory:
o = Object.new
def o.to_json(a) = raise
10.times do
100_000.times do
begin
JSON(o)
rescue
end
end
puts `ps -o rss= -p #{$$}`
end

Some extensions (like stringio) may need to differentiate between
chilled strings and frozen strings.
They can now use rb_str_chilled_p but must check for its presence since
the function will be removed when chilled strings are removed.

When `RUBY_DEBUG` is set, accessing a class in an invalid object will
cause a breakpoint trap instead of a segfault on some implementations.

The simple names in `default_exclude_exts` do not match extension
paths under gems.
Extract each gem name from the gemspec file at the top level of each
gem directory. For example, if `ext` is `syslog-0.1.2/ext/syslog/`,
find out `syslog-0.1.2/syslog.gemspec` and take the base name `syslog`
without the suffix `.gemspec`.

The size of `struct parser_params` is 8 bytes difference in `ripper_s_allocate` and `rb_ruby_parser_allocate` when the universal parser is
enabled.
This causes a situation where `*r->p` is not fully initialized in `ripper_s_allocate` as shown below.
```console
(gdb) p *r->p
$2 = {heap = 0x0, lval = 0x0, yylloc = 0x0, lex = {strterm = 0x0, gets = 0x0, input = 0, string_buffer = {head = 0x0, last = 0x0}, lastlin
e = 0x0,
nextline = 0x0, pbeg = 0x0, pcur = 0x0, pend = 0x0, ptok = 0x0, gets_ = {ptr = 0, call = 0x0}, state = EXPR_NONE, paren_nest = 0, lpar
_seen = 0,
debug = 0, has_shebang = 0, token_seen = 0, token_info_enabled = 0, error_p = 0, cr_seen = 0, value = 0, result = 0, parsing_thread = 0, s_value = 0,
s_lvalue = 0, s_value_stack = 2097}
````
This seems to cause `double free or corruption (!prev)` and SEGV.
So, fixing this by introduce `rb_ripper_parser_params_allocate` and `rb_ruby_parser_config` functions for Ripper, and `struct parser_params` same size is returned.

[Feature #20205]
As a path toward enabling frozen string literals by default in the future,
this commit introduce "chilled strings". From a user perspective chilled
strings pretend to be frozen, but on the first attempt to mutate them,
they lose their frozen status and emit a warning rather than to raise a
`FrozenError`.
Implementation wise, `rb_compile_option_struct.frozen_string_literal` is
no longer a boolean but a tri-state of `enabled/disabled/unset`.
When code is compiled with frozen string literals neither explictly enabled
or disabled, string literals are compiled with a new `putchilledstring`
instruction. This instruction is identical to `putstring` except it marks
the String with the `STR_CHILLED (FL_USER3)` and `FL_FREEZE` flags.
Chilled strings have the `FL_FREEZE` flag as to minimize the need to check
for chilled strings across the codebase, and to improve compatibility with
C extensions.
Notes:
- `String#freeze`: clears the chilled flag.
- `String#-@`: acts as if the string was mutable.
- `String#+@`: acts as if the string was mutable.
- `String#clone`: copies the chilled flag.

As preparation for https://bugs.ruby-lang.org/issues/20205
making sure the test suite is compatible with frozen string
literals is making things easier.

This frees FL_USER0 on both T_MODULE and T_CLASS.
Note: prior to this, FL_SINGLETON was never set on T_MODULE,
so checking for `FL_SINGLETON` without first checking that
`FL_TYPE` was `T_CLASS` was valid. That's no longer the case.
|
|
Previous documentation is stating the opposite (that the method won't
work for CRuby).
|
|
The documentation for `rb_enc_interned_str_cstr` notes that `enc` can be
a null pointer, but this currently causes a segmentation fault when
trying to autoload the encoding. This commit fixes the issue by checking
for NULL before calling `rb_enc_autoload`.

ASAN greatly increases the memory footprint of Ruby, so these static
thresholds are not appropriate. There's no real need to run these tests
under ASAN.
