Fix stub for Phar::setStub()
This fixes multiple issues:
* The first parameter may be resource|string.
* It's an overloaded signature. The second parameter cannot be
passed if the first one is a string. Use UNKNOWN default
value for that reason.
* Make parameter names in PharData::setStub() match those in
Phar.
Fix #80595: Resetting POSTFIELDS to empty array breaks request
This is mainly to work around https://github.com/curl/curl/issues/6455,
but not building the mime structure for empty hashtables is a general
performance optimization, so we do not restrict it to affected cURL
versions (7.56.0 to 7.75.0).
The minor change to bug79033.phpt is unexpected, but should not matter
in practice.

Add support for union types for internal functions
This closes the last hole in the supported types for internal
function arginfo types. It's now possible to represent unions of
multiple classes. This is done by storing them as TypeA|TypeB and
PHP will then convert this into an appropriate union type list.

Fixed bug #80545
This converts the remaining "non well-formed" warnings in bcmath
to ValueErrors, in line with the other warning promotions that
have been performed in this extension.
CentOS 7 ships with re2c 0.13.5 by default, so we should not have
bumped the required re2c version to 0.13.7. However, 0.13.5 does not
support default rules, so we cannot use them to fix bug 76813.
Avoid modifying the return value of readline_completion_function()
The internal function `_readline_command_generator()` modifies the
internal array pointer of `readline_completion_function()`'s return
value. We therefore separate the array, what also avoids failing
assertions regarding the array refcount.

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.
