Fix #78792: zlib.output_compression disabled by Content-Type: image/

Disabling output compression for images has served to fix bug #16109,
where zlib compressed images apparently have caused issues with
Navigator 4. This shouldn't be an issue with somewhat contemporary
browsers. Other than that, this is an arbitrary restriction – why
don't we disable the compression for some other media types as well
(e.g. video/* and audio/*)? All in all, we should leave that decision
to userland.

Closes GH-6198.

Fix #22986: odbc_connect() may reuse persistent connection

`odbc_connect()` should not reuse persistent connections, since that
prohibits multiple concurrent connections, which are occasionally
desireable. We fix that by no longer looking for already cached
connections when `odbc_connect()` is called, and instead creating a new
connection instead.

SplFixedArray is Aggregate, not Iterable

One strange feature of SplFixedArray was that it could not be used in nested foreach
loops. If one did so, the inner loop would overwrite the iteration state of the outer
loop.

To illustrate:

$spl = SplFixedArray::fromArray([0, 1]);
foreach ($spl as $a) {
foreach ($spl as $b) {
echo "$a $b";
}
}

Would only print two lines:

0 0
0 1

Use the new InternalIterator feature which was introduced in ff19ec2df3 to convert
SplFixedArray to an Aggregate rather than Iterable. As a bonus, we get to trim down
some ugly code! Yay!

Return empty array for no rows in pg_fetch_all()

This makes it line up with pg_fetch_all_columns(), as well as
similar functions in other exts, such as mysqli_fetch_all().

Deprecate pgsql function aliases

These have been documentation-deprecated for a very long time,

Drop support for libmysqlclient < 5.5

Given how little maintenance the libmysqlclient driver sees, be
more aggressive in dropping old version support here.

Allow array_diff() and array_intersect() with single array argument

Both of these functions are well-defined when used with a single
array argument -- rejecting this case was an artificial limitation.
This is not useful when called with explicit arguments, but removes
edge-cases when used with argument unpacking:

// OK even if $excludes is empty.
array_diff($array, ...$excludes);

// OK even if $arrays contains a single array only.
array_intersect(...$arrays);

This matches the behavior of functions like array_merge() and
array_push(), which also allow calls with no array or a single
array respectively.

Drop support for crypt() without explicit salt

crypt() without salt generates a weak $1$ MD5 hash. It has been
throwing a notice since 2013 and we provide a much better alternative
in password_hash() (which can auto-generate salts for strong
password hashes), so keeping this is just a liability.
