PDO MySQL: Use mysqlnd column names
mysqlnd already creates interned zend_strings for us, so let's
make use of them.
This also required updating the PDO case changing code to work
with potentially shared strings. For the lowercasing, use the
optimized zend_string_tolower() implementation.

Don't truncate the file length to unsigned int...
I have no idea whether that fully fixes the problem because the
process gets OOM killed before finishing, but at least the
immediate parse error is gone now.
JIT: Update invalid opcache.jit INI value message to include "tracing" and "function" values
`opcache.jit` accepts `tracing` and `function` as aliases, but they were not mentioned in the start-up INI warning message.
This updates the error message to include all possible values.

IBM i PASE doesn't support ITIMER_PROF
Like Cygwin, this platform needs to use a real-time timer.
This was based on a patch by @kadler, but it didn't handle unsetting
the timer, so the timeout would continue to be active, triggering
`hard_timeout` unexpectedly. The patch is fixed to handle unsetting.
Like the test title and some comments in this test describe, this test
was supposed to have `::prepare()` failing because `LOAD DATA INFILE`
would not be supported as prepared statement, and then the test checks
whether follow-up queries would succeed. However, `LOAD DATA INFILE`
is supported for prepared statements at least on Windows with mysqlnd,
so the test does no longer test what it is supposed to do. Therefore,
we drop it.

PDO MySQL: Use stmt_next_result with libmysqlclient as well
libmysqlclient added this function in version 5.5, which happens
to be the minimum we support. If we have a prepared statement,
we should use it on both mysqlnd and libmysqlclient, even if the
handling afterwards is different.
This fixes error handling with native prepared statements.

Fixed bug #62889
Our minimum libmysqlclient version requirement is high enough
that we don't need to check for MYSQL_OPT_LOCAL_INFILE support.
However, the mysql_get_option() function seems to only be available
since 5.7 (though it's really hard to find any definitie information
on when MySQL introduced certain functions or changes...) so we
need to store the value of the flag locally to make it available
through getAttribute().

When a driver reports an error during EVT_ALLOC (and some over EVTs),
make sure we handle it as usual, i.e. warn or throw.
This requires some adjustments in PDO PgSQL to stop manually doing

Unfortunately the PDO PgSQL error messages regress because of this,

seem to be an ability to skip it right now.

Fixed bug #79872 by improving error message
The actual behavior here is correct, but the previous error
message was misleading, as neither fetchAll() nor buffered queries
would help in this situation. Instead it is necessary to consume
all rowsets, which can be done by either unsetting the statement
or calling closeCursor().

Handle changing column count in mysqlnd result binding
If the count changes from prepare to execute and result_bind is
alreadly allocated, reallocate it there.
This is something of a hack. It would be cleaner to require that
result bindings are registered only after execute, when the final
result set fields are known. But mysqli at least directly exposes
this to the user, so we have no guarantee.

PDO MySQL: Normalize handling of empty stored procedure result set
MySQL always returns a trailing empty result set for stored
procedure calls, which is used to convey status information.
The PDO MySQL implementation is presently confused about what to
do with it: If mysqlnd is used and native prepared statements are
used, this result set is skipped. In all other cases it is not
skipped. We also have quite a few XFAILed tests relating to this.
This patch normalizes (for PHP-8.0 only) the behavior towards
always retaining the empty result set. This is simply how MySQL
stored procedures work (some expletives omitted here) and we can't
distinguish this "useless" result set from an empty result of a
multi query. Multi queries are not a concern for native prepared
statements, as PDO does not allow them in that case, but they are
a concern for emulated prepared statements.
When `php_zlib_deflate_filter()` is called with `PSFS_FLAG_FLUSH_INC`
but without new buckets being available (e.g. because a user calls
`rewind()` after writing to the stream), we have to make sure that any
pending data are flushed. This could basically be done like in the
attached patch[1], but that could cause unnessary flushes, which can be
harmful for compression, and adds unnecessary flush markers to the
stream. Thus, we use the `php_zlib_filter_data.finished` field, which
has not been used for `zlib.deflate` filters, and properly keep track
of the need to flush.
Fix #77069: stream filter loses final block of data
Reading from a stream may return greater than zero, but nonetheless the
stream's EOF flag may have been set. We have to cater to this
condition by setting the close flag for filters.
We also have to cater to that change in the zlib.inflate filter:
If `inflate()` is called with flush mode `Z_FINISH`, but the output
buffer is not large enough to inflate all available data, it fails with
`Z_BUF_ERROR`. However, `Z_BUF_ERROR` is not fatal; in fact, the zlib
manual states: "If deflate returns with Z_OK or Z_BUF_ERROR, this
function must be called again with Z_FINISH and more output space
(updated avail_out) but no more input data, until it returns with
Z_STREAM_END or an error." Hence, we do so.

Fix #75102: `PharData` says invalid checksum for valid tar
Apparently, there are broken tarballs out there which are actually in
ustar format, but did not write the `ustar` marker. Since popular tar
tools like GNU tar and 7zip have no issues dealing with such tarballs,
Phar should also be more resilient.
Thus, when the first checksum check of a tarball in (presumed) in old-
style format fails, we check whether the checksum would be suitable for
ustar format; if so, we treat the tarball as being in ustar format.
