[Bug #17780] Fix Method#super_method for module alias
Method#super_method crashes for aliased module methods because they are
not defined on a class. This bug was introduced in
c60aaed1856b2b6f90de0992c34771830019e021 as part of bug #17130.

Fix singleton class cloning
Before this commit, `clone` gave different results depending on whether the original object
had an attached singleton class or not.
Consider the following setup:
```
class Foo; end
Foo.singleton_class.define_method(:foo) {}
obj = Foo.new
obj.singleton_class if $call_singleton
clone = obj.clone
```
When `$call_singleton = false`, neither `obj.singleton_class.singleton_class` nor
`clone.singleton_class.singleton_class` own any methods.
However, when `$call_singleton = true`, `clone.singleton_class.singleton_class` would own a copy of
`foo` from `Foo.singleton_class`, even though `obj.singleton_class.singleton_class` does not.
The latter case is unexpected and results in a visibly different clone, depending on if the original object
had an attached class or not.

Don't double fractional seconds when passing timezone object to Time.new
I found that fractional seconds were doubled when using the timezone
feature of Time in Sequel's named_timezones extension (which uses
TZInfo for the timezone object), and traced the problem to this code.
There is no subsecx being modified in the utc_to_local call below
this, and I'm not sure why you would want to add in the fractional
seconds unless you assumed the timezone conversion would drop the
existing fractional seconds (TZInfo doesn't drop fractional seconds).
Subsecond of Time::tm should be 0

Fix Method#super_method for aliased methods
Previously, Method#super_method looked at the called_id to
determine the method id to use, but that isn't correct for
aliased methods, because the super target depends on the
original method id, not the called_id.
Additionally, aliases can reference methods defined in other
classes and modules, and super lookup needs to start in the
super of the defined class in such cases.
This adds tests for Method#super_method for both types of
aliases, one that uses VM_METHOD_TYPE_ALIAS and another that
does not. Both check that the results for calling super
methods return the expected values.
To find the defined class for alias methods, add an rb_ prefix
to find_defined_class_by_owner in vm_insnhelper.c and make it
non-static, so that it can be called from method_super_method
in proc.c.
This bug was original discovered while researching [Bug #11189].

brace the fact that lchmod(2) can EOPNOTSUPP
Musl libc has this function as a tiny wrapper of fchmodat(3posix). On
the other hand Linux kernel does not support changing modes of a symlink.
The operation always fails with EOPNOTSUPP. This fchmodat behaviour is
defined in POSIX. We have to take care of such exceptions.

Don't display singleton class in Method#inspect unless method defined there
Previously, if an object has a singleton class, and you call
Object#method on the object, the resulting string would include
the object's singleton class, even though the method was not
defined in the singleton class.
Change this so the we only show the singleton class if the method
is defined in the singleton class.

time.c (find_time_t): fix round-to-zero bug
`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.

Fixed heap-use-after-free

replacement string buffer just before using it, for the case of
replacement with the receiver string itself. [Bug #16105]

should not free local hook_list here.
exec_hooks_postcheck() clean executed hook_list if it is needed.
list_exec is freed if there are no events and this list is local
event (connected to specific iseq). However, iseq keeps to point
this local hook_list, freed list. To prevent this situation,
do not free hook_list here even if it has no events.
