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.

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.

This is an unavoidable breaking change to both the type and
parameter name.
The assertion that was supposed to prevent this was overly lax
and accepted any object type for string parameters.
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.
Fixes bug #64638, bug #72862, bug #77935.
Closes GH-6518.
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.
