Phar signatures practically are of limited size; for the MD5 and SHA
hashes the size is fixed (at most 64 bytes for SHA512); for OpenSSL
public keys there is no size limit in theory, but "64 KiB ought to be
good enough for anybody". So we check for that limit, to avoid fatal
errors due to out of memory conditions.
Since it is neither possible to have the signature compressed in the
ZIP archive, nor is it possible to manually add a signature via Phar,
we use ZipArchive to create a suitable archive for the test on the fly.

Don't mark cpu_supports functions as always inline
The use of no-sanitize may result in an inlining failure, which
will be promoted into a compile error by always-inline. Use a
normal inlining hint without enforcing it.
Fix #62004: SplFileObject: fgets after seek returns wrong line
As it is, `::seek(0)` sets the file pointer to the beginning of the
file, but `::seek($n)` where `$n > 0` sets the file pointer to the
beginning of the following line, having line `$n` already read into the
line buffer. This is pretty inconsistent; we fix it by always seeking
to the beginning of the line.
We also add a test case for the duplicate bug #46569.

Next attempt to fix bug #80368
Apparently treating LibreSSL as OpenSSL 1.1 is not just something
we did in our code, it's something that upstream LibreSSL claims,
despite not actually being compatible. Duh.
Check for EVP_CIPH_OCB_MODE instead, which should reliably
determine support...

Rename XmlParser to XMLParser for consistency with XMLWriter/XMLReader

Checking for a valid Unique ID (UID) cannot use the convenience macro as they might
be larger than the message number which has for maximum value the total number of
current messages available in the mailbox.

Suppress stream errors in mysqlnd
mysqlnd currently sets error_reporting=0 to suppress errors while
writing to streams. Unfortunately these errors are still visible
to userland error handlers, which is a source of confusion.
See for example https://bugs.php.net/bug.php?id=80412.
Instead add a stream flag that suppresses the emission of
read/write errors in the first place, and set it in mysqlnd.
I think it might be useful to have this option for userland as
well in the future, but for now this is just an internal
mechanism.

Only replace IN_ARRAY result type for JMPZ/JMPNZ
Replacing the result type in the general case is dangerous,
because not all opcodes support both VAR and TMP. One common case
is the in_array() result being passed to SEND_VAR, which would
have to be changed to SEND_VAL.
Rather than complicating this logic, reduce the scope to only
doing the type replacement for JMPZ and JMPNZ. The only reason
we're doing this in the first place is to enable the smart branch
optimization, so we can limit it to the relevant opcodes. Replacing
the result type may be marginally useful in other cases as well
(as it may avoid reference checks), but not worth the bother.

Don't check for throwing calls in sccp function evaluation
We only need to reject functions that could warn (or have runtime
dependent behavior). If a function can throw in some cases, just
let it and discard the result.

Fix handling of sccp exceptions
We should clear the exception *before* we destroy the execute_data.

Fix AVX detection
Our CPU detection code currently only checks whether hardware
support for AVX exists. However, we also need to check for operating
system support for XSAVE, as well as whether XCR0 has the SSE and
AVX bits set.
If this is not the case, unset the AVX and AVX2 bits in the cpuinfo
structure.
Hopefully this resolves our issues with CPU support detection.

Only use travis for cron jobs
Our primary CI has been Azure Pipelines for a while now already.
Travis was primarily retained as a) a fast feedback builder and
b) to test architectures not available elsewhere.
Due to Travis CI open source policy changes, Travis is no longer
useful as a fast feedback builder. As such, only use it for cron
job builds.
As the alternate path in this test covers all supported MySQL and MariaDB
versions and a signifant portion of unsupported versions lets keep it simple.

Avoid direct calls to zend_cpu_supports()
While the use of zend_cpu_supports_*() is only strictly necessary
inside ifunc resolvers, where the cpu state has not been initialized
yet, we should prefer the compiler builtins in all cases.
