PHP’s implementation of crypt_blowfish differs from the upstream Openwall
version by adding a “PHP Hack”, which allows one to cut short the BCrypt salt
by including a `$` character within the characters that represent the salt.
Hashes that are affected by the “PHP Hack” may erroneously validate any
password as valid when used with `password_verify` and when comparing the
return value of `crypt()` against the input.
The PHP Hack exists since the first version of PHP’s own crypt_blowfish
implementation that was added in 1e820eca02.
No clear reason is given for the PHP Hack’s existence. This commit removes it,
because BCrypt hashes containing a `$` character in their salt are not valid
BCrypt hashes.
The check that was supposed to check whether the array slot was UNDEF
was wrong and never triggered. This resulted in a replacement with the
empty string or the wrong string instead of the correct one. The correct
check pattern can be observed higher up in the function's code.

Directly referring to a constant of an undefined throws an exception;
there is not much point in `constant()` raising a fatal error in this
case.
Closes GH-9907.
As of PHP 8.1.0, the `--EXTENSIONS-- section is properly supported, and
CIs may make use of that (our AppVeyor CI does). Thus it is important
to list required extensions there, since otherwise they may not be
loaded, causing the test to be skipped, or worse, to be borked.
Commit fbe3059 included an unintended change to the test which checks if
dns_get_record populates its additional parameter. This patch reverts
such change.
The issue was not detected by the CIs because their tests run in
the --offline mode, and the test in question needs internet connection.
Closes GH-9625.
While the reason-phrase in a HTTP response status line is usually
short, there is no actual limit specified by the RFCs. As such, we
must not assume that the line fits into the buffer (which is currently
128 bytes large).
Since there is no real need to present the complete status line, we
simply read and discard the rest of a long line.

This fix is another solution to replace d0527427be, use zend_try and zend_catch to make sure persistent stream will be released when error occurred.
Closes GH-9332.
This reverts commit d0527427be.
This patch makes Swoole/Swow can not work anymore, because Coroutine will yield to another one during socket operation, EG(record_errors) assertion will always fail, and zend_begin_record_errors() was only used during compile time before.
Note: zend_emit_recorded_errors() and the typo fix are reserved.
This is not actually related to SSL handshake but stream socket creation
which does not clean errors if the error handler is set. This fix
prevents emitting errors until the stream is freed.
The comparator function used at ksort in SORT_REGULAR mode
need to be consistent with basic comparison rules. These rules
were changed in PHP-8.0 for numeric strings, but comparator
used at ksort kept the old behaviour. It leads to inconsistent
situations, when after ksort the first key is GREATER than some
of the next ones by according to the basic comparison operators.
Closes GH-9293.
Apparently, on Cirrus CI FreeBSD chmodding a file to 0444 doesn't make
it readonly. So in this case, we skip the test.

We explicitly check for an exception after the logging attempt, and
bail out in that case.
