Apparently, the lower bound check is missing, which results in overflow & wrapping later on in RB_INT2FIX

This flag isn't really meant to be public, it's an implementation
detail of Ruby.
And checking it before calling `rb_copy_generic_ivar` only save
a function call.

While working on a separate issue we found that in some cases
`ary_heap_realloc` was being called on frozen arrays. To fix this, this
change does the following:
1) Updates `rb_ary_freeze` to assert the type is an array, return if
already frozen, and shrink the capacity if it is not embedded, shared
or a shared root.
2) Replaces `rb_obj_freeze` with `rb_ary_freeze` when the object is
always an array.
3) In `ary_heap_realloc`, ensure the new capa is set with
`ARY_SET_CAPA`. Previously the change in capa was not set.
4) Adds an assertion to `ary_heap_realloc` that the array is not frozen.
Some of this work was originally done in
https://github.com/ruby/ruby/pull/2640, referencing this issue
https://bugs.ruby-lang.org/issues/16291. There didn't appear to be any
objections to this PR, it appears to have simply lost traction.
The original PR made changes to arrays and strings at the same time,
this PR only does arrays. Also it was old enough that rather than revive
that branch I've made a new one. I added Lourens as co-author in addtion
to Aaron who helped me with this patch.
The original PR made this change for performance reasons, and while
that's still true for this PR, the goal of this PR is to avoid
calling `ary_heap_realloc` on frozen arrays. The capacity should be
shrunk _before_ the array is frozen, not after.

::httpdate
#to_date
#to_time
#to_datetime
In behalf of ::httpdate, I've introduced section "Argument limit" that can be pointed to by various Date methods (similar to existing section "Argument start"). This will involve 8 already-enhanced methods plus 8 more not yet done.

Brings a dozen call-seq schemas into compliance with the doc guide.
Adds links to section "Argument start" where needed.
Revises (minorly) ::today.
Otherwise, does not disturb existing text.

`Date.parse` now raises an ArgumentError when a given date string is
longer than 128. You can configure the limit by giving `limit` keyword
arguments like `Date.parse(str, limit: 1000)`. If you pass `limit: nil`,
the limit is disabled.
Not only `Date.parse` but also the following methods are changed.
* Date._parse
* Date.parse
* DateTime.parse
* Date._iso8601
* Date.iso8601
* DateTime.iso8601
* Date._rfc3339
* Date.rfc3339
* DateTime.rfc3339
* Date._xmlschema
* Date.xmlschema
* DateTime.xmlschema
* Date._rfc2822

In AIX, altzone exists in the standard library but is not declared
in time.h. By 524513be39, have_var
and try_var in mkmf recognizes a variable that exists in a library
even when it is not declared. As a result, in AIX, HAVE_ALTZONE
is defined, but compile fails due to the lack of the declaration.
