We know that this is a heap-allocated object (a CLASS, MODULE, or
ICLASS) so we don't need to check if it is an immediate value. This
should be very slightly faster.
Avoids genereating a "throwaway" sentinel class serial. There wasn't any
read harm in doing so (we're at no risk of exhaustion and there'd be no
measurable performance impact), but if feels cleaner that all class
serials actually end up assigned and used (especially now that we won't
overwrite them in a single method definition).
rb_clear_method_cache_by_class calls rb_class_clear_method_cache
recursively on subclasses, where it will bump the class serial and clear
some other data (callable_m_tbl, and some mjit data).
Previously this could end up taking a long time to clear all the classes
if the module was included a few levels deep and especially if there
were multiple paths to it in the dependency tree (ie. a class includes
two modules which both include the same other module) as we end up
revisiting class/iclass/module objects multiple times.
This commit avoids revisiting the same object, by short circuiting when
revisit the same object. We can check this efficiently by comparing the
class serial of each object we visit with the next class serial at the
start. We know that any objects with a higher class serial have already
been visited.
TCSAFLUSH discards the buffer read before the mode change, which makes
IRB ignore the buffer input immediately after invoked. TCSANOW
preserves the buffer.

`find_time_t` did not work correctly for year older than the Epoch
because it used C's integer division (which rounds negative to zero).
For example, `TIme.new(1933)` returned a wrong time whose year is 1922
in Asia/Kuala_Lumpur because there is no 00:00:00 1st Jan. 1933 in the
time zone.
```
$ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)'
1932-12-31 00:00:00 +0700
```
This change fixes the issue by using `DIV` macro instead of `/`.
Now `Time.new(1933)` returns a time in 1933.
```
$ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)'
1933-01-01 00:20:00 +0720
```
[Bug #16159]
This reverts commit 5105240b1e.
In RFC 2616:
```
deflate
The "zlib" format defined in RFC 1950 [31] in combination with
the "deflate" compression mechanism described in RFC 1951 [29].
```
So "Content-Encoding: deflate" means zlib format, not raw deflate.
[Bug #11268]
Net::HTTP had used `Zlib::Inflate.new(32 + Zlib::MAX_WBITS)` for all
content encoding (deflate, zlib, and gzip).
But the argument `32 + Zlib::MAX_WBITS` means zlib and gzip decoding
with automatic header detection, so (raw) deflate compression had not
been supported.
This change makes it support raw deflate correctly by passing an
argument `-Zlib::MAX_WBITS` (which means raw deflate) to
`Zlib::Inflate.new`. All deflate-mode tests are fixed too.
[Bug #11268]
The equation shall hold for every call cache. However prior to this
changeset cc->me could be updated without also updating cc->def. Let's
make it sure by introducing new macro named CC_SET_ME which sets cc->me
and cc->def at once.
