Fix/improve mysqli stubs
* mysqli_commit $flags default value is 0, not -1.
* A number of functions cannot actually return null.
* mysqli_poll parameter names were incorrect, as this function
has a different signature from select.
* fetch functions apart from fetch_all can return false on failure.
Fix #77565: Incorrect locator detection in ZIP-based phars
We must not assume that the first end of central dir signature in a ZIP
archive actually designates the end of central directory record, since
the data in the archive may contain arbitrary byte patterns. Thus, we
better search from the end of the data, what is also slightly more
efficient.
There is, however, no way to detect the end of central directory
signature by searching from the end of the ZIP archive with absolute
certainty, since the signature could be part of the trailing comment.
To mitigate, we check that the comment length fits to the found
position, but that might still not be the correct position in rare
cases.

gdbinit: use ____print_str to print htable keys
I noticed this problem while dumping the contents of EG(function_table),
where keys for closures start with a null byte. printf interprets this
as a zero-length string and emits nothing. This allows the key to be
rendered properly in readable form.
Fix #77423: parse_url() will deliver a wrong host to user
To avoid that `parse_url()` returns an erroneous host, which would be
valid for `FILTER_VALIDATE_URL`, we make sure that only userinfo which
is valid according to RFC 3986 is treated as such.
For consistency with the existing url parsing code, we use ctype
functions, although that is not necessarily correct.

Fix #80384: limit read buffer size
In the case of a stream with no filters, php_stream_fill_read_buffer
only reads stream->chunk_size into the read buffer. If the stream has
filters attached, it could unnecessarily buffer a large amount of data.
With this change, php_stream_fill_read_buffer only proceeds until either
the requested size or stream->chunk_size is available in the read buffer.

MySQLnd: Support cursors in store/get result
This fixes two related issues:
1. When a PS with cursor is used in store_result/get_result,
perform a COM_FETCH with maximum number of rows rather than
silently switching to an unbuffered result set (in the case of
store_result) or erroring (in the case of get_result).
In the future, we might want to make get_result unbuffered for
PS with cursors, as using cursors with buffered result sets
doesn't really make sense. Unlike store_result, get_result
isn't very explicit about what kind of result set is desired.
2. If the client did not request a cursor, but the server reports
that a cursor exists, ignore this and treat the PS as if it
has no cursor (i.e. to not use COM_FETCH). It appears to be a
server side bug that a cursor used inside an SP will be reported
to the client, even though the client cannot use the cursor.

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.

Fix bug #80523
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.
