[Bug #19924] Source code should be unsigned char stream
Use `peekc` or `nextc` to fetch the next character, instead of reading
from `lex.pcur` directly, for compilers that plain char is signed.

[Bug #19985] Raise LoadError with the converted feature name
`Kernel#require` converts feature name objects that have the `to_path`
method such as `Pathname`, but had used the original object on error
and had resulted in an unexpected `TypeError`.

fix memory leak in vm_method
This introduces a unified reference_count to clarify who is referencing a method.
This also allows us to treat the refinement method as the def owner since it counts itself as a reference

Fix memory leak in complemented method entries
[Bug #19894]
When a copy of a complemented method entry is created, there are two
issues:
1. IMEMO_FL_USER3 is not copied, so the complemented status is not
copied over.
2. In rb_method_entry_clone we increment both alias_count and
complemented_count. However, when we free the method entry in
rb_method_definition_release, we only decrement one of the two
counters, resulting in the rb_method_definition_t being leaked.

Fix regression when testing inclusion in unbounded ranges
Caused by 04a92a6764bf678919cf4b68a27496a39d6b886a. This treats
unbounded ranges of arbitrary objects the same as how unbounded
string ranges are treated:
(..x) === y # (y <=> x) <= 0
(...x) === y # (y <=> x) < 0
(x..) === y # (x <=> y) <= 0

If two threads are running, with one calling waitpid(-1), and another
calling waitpid($some_pid), and then $some_other_pid exits, we would
expect the waitpid(-1) call to retrieve that exit status; however, it
cannot actually do so until $some_pid _also_ exits.
This patch fixes the issue by unconditionally checking for pending
process group waits on SIGCHLD, and then allowing pending pid-only waits
to "steal" the notification.
[Fixes #19387]

Fix memory leak for incomplete lambdas
[Bug #19836]
The parser does not free the chain of `struct vtable`, which causes
memory leaks.
The following script reproduces this issue:
```
10.times do
100_000.times do
Ripper.parse("-> {")
end
puts `ps -o rss= -p #{$$}`
end
```

Fix memory leak in parser for incomplete tokens

Fix crash in NoMethodError for dummy frames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[Bug #19793]
Dummy frames are created at the top level when requiring another file.
While requiring a file, it will try to convert using encodings. Some of
these encodings will not respond to to_str. If method_missing is
redefined on Object, then it will call method_missing and attempt raise
an error. However, the iseq is invalid as it's a dummy frame so it will
write an invalid iseq to the created NoMethodError.
The following script crashes:
```
GC.stress = true
class Object
public :method_missing
end
File.write("/tmp/empty.rb", "")
require "/tmp/empty.rb"
```
With the following backtrace:
```

Fix crash in Time on 32-bit systems
[Bug #19575]
struct vtm is packed causing it to have a size that is not aligned on
32-bit systems. When allocating it on the stack, it will have unaligned
addresses which means that the fields won't be marked by the GC when
scanning the stack (since the GC only marks aligned addresses). This can
cause crashes when the fields are heap allocated objects like Bignums.
This commit moves the flags in struct time_object into struct vtm for
space efficiency and removes the need for packing.
This is an example of a crash:

Fix memory leak for iclass
[Bug #19550]
If !RCLASS_EXT_EMBEDDED (e.g. 32 bit systems) then the rb_classext_t is
allocated throug malloc so it must be freed.
The issue can be seen in the following script:
```
20.times do
100_000.times do
mod = Module.new
Class.new do
include mod
end
end
# Output the Resident Set Size (memory usage, in KB) of the current Ruby process
puts `ps -o rss= -p #{$$}`
end
```
Before this fix, the max RSS is 280MB, while after this change, it's
30MB.

IO::Buffer#resize: Free internal buffer if new size is zero (#7569)
`#resize(0)` on an IO::Buffer with internal buffer allocated will
result in calling `realloc(data->base, 0)`. The behavior of `realloc`
with size = 0 is implementation-defined (glibc frees the object
and returns NULL, while BSDs return an inaccessible object). And
thus such usage is deprecated in standard C (upcoming C23 will make it
UB).
To avoid this problem, just `free`s the memory when the new size is zero.

Fix crash when allocating classes with newobj hook
We need to zero out the whole slot when running the newobj hook for a
newly allocated class because the slot could be filled with garbage,
which would cause a crash if a GC runs inside of the newobj hook.
For example, the following script crashes:
```
require "objspace"
GC.stress = true
ObjectSpace.trace_object_allocations {
100.times do
Class.new
end
}
```

YJIT: Generate Block::entry_exit with block entry PC
Previously, when Block::entry_exit is requested from any instruction
that is not the first one in the block, we generated the exit with an
incorrect PC. We should always be using the PC for the entry of the
block for Block::entry_exit.
It was a simple typo. The bug was [introduced][1] while we were
refactoring to use the current backend. Later, we had a chance to spot
this issue while [preparing][2] to enable unused variable warnings, but
didn't spot the issue.

The class variable cache that was added in
https://github.com/ruby/ruby/pull/4544 changed the behavior of class
variables on cloned classes. As reported when a class is cloned AND a
class variable was set, and the class variable was read from the
original class, reading a class variable from the cloned class would
return the value from the original class.
This was happening because the IC (inline cache) is stored on the ISEQ
which is shared between the original and cloned class, therefore they
share the cache too.
To fix this we are now storing the `cref` in the cache so that we can
check if it's equal to the current `cref`. If it's different we don't
want to read from the cache. If it's the same we do. Cloned classes
don't share the same cref with their original class.
This will need to be backported to 3.1 in addition to 3.2 since the bug
exists in both versions.
We also added a marking function which was missing.
