In libc-client 2007f `data` is declared as `unsigned char *`; there may
be variants which declare it as `void *`, but in any case picky
compilers may warn about a pointer type mismatch in the conditional
(and error with `-W-error`), so we're adding a `char *` cast for good
measure.
The original fix for that bug[1] broke the formerly working composition
of message/rfc822 messages, which results in a segfault when freeing
the message body now. While `imap_mail_compose()` does not really
support composition of meaningful message/rfc822 messages (although
libc-client appears to support that), some code may still use this to
compose partial messages, and using string manipulation to create the
final message.
The point is that libc-client expects `TYPEMESSAGE` with an explicit
subtype of `RFC822` to have a `nested.msg` (otherwise there will be a
segfault during free), but not to have any `contents.text.data` (this
will leak otherwise).

Closes GH-6343.
If unsupported `$search_criteria` are passed to `imap_sort()`, the
function returns an empty array, but there is also an error on the
libc-client error stack ("Unknown search criterion: UNSUPPORTED
(errflg=2)"). If, on the other hand, unsupported `$criteria` or
unsupported `$flags` are passed, the function returns `false`. We
solve this inconsistency by returning `false` for unsupported
`$search_criteria` as well.
Closes GH-6332.
Unless `topbod` is of `TYPEMULTIPART`, `mail_free_body()` does not free
the `nested.part`; while we could do this ourselves, instead we just
ignore additional bodies in this case, i.e. we don't attach them in the
first place.
Closes GH-6321.
If the RHS has INDIRECT elements, we do not those to be added to
the LHS verbatim. As we're using UPDATE_INDIRECT, we might even
create a nested INDIRECT that way.
This is a side-quest of oss-fuzz #26245.
We separate the input arrays and all sub-arrays to avoid modification
of the passed parameters.
This should be rewritten to use `zend_string`s for the "master" branch.
Closes GH-6316.
The documentation of `tidyNode::isHtml()` states that this method
"checks if a node is part of a HTML document". That is, of course,
nonsense, since a tidyNode is "an HTML node in an HTML file, as
detected by tidy."
What this method is actually supposed to do is to check whether a node
is an element (unless it is the root element). This has been broken by
commit d8eeb8e[1], which assumed that `enum TidyNodeType` would
represent flags of a bitmask, what it does not.

There is no such thing as the "end of the unix epoch", and if it was,
it would certainly not be 2037-10-11T02:00:00. There is, however,
potential integer overflow which we need to avoid.
Closes GH-6288.
