Remove deprecated getaddrinfo flags

The AI_IDN_ALLOW_UNASSIGNED and AI_IDN_USE_STD3_ASCII_RULES have
been deprecated by glibcs, and PHP 7.4 follows this deprecation.

This removes the offending flags for PHP 8.0.

Extend CURLFile to support streams

Due to former restrictions of the libcurl API, curl multipart/formdata
file uploads supported only proper files. However, as of curl 7.56.0
the new `curl_mime_*()` API is available (and already supported by
PHP[1]), which allows us to support arbitrary *seekable* streams, which
is generally desirable, and particularly resolves issues with the
transparent Unicode and long part support on Windows (see bug #77711).

Note that older curl versions are still supported, but CURLFile is
still restricted to proper files in this case.

ext/xml: Use object instead of resource

Use an XmlParser object instead of a resource. This is an internal
representation change, not a conversion to OO APIs. XmlParser objects
cannot be explicitly constructed, they are created through the usual
xml_parser_* APIs.

This change allows us to provide a proper get_gc() implementation,
thus resolving bugs #72793 and #76874.

xml_parser_free() is a no-op now and need not be called anymore.

Added range options to the float validation filter

php_filter_int (called via the constant FILTER_VALIDATE_INT) has the options min_range
and max_range. they allow the user to not only test if a value is a double but also if
the value is inside a specific range. php_filter_float (called via the constant
FILTER_VALIDATE_FLOAT) didn't provide this yet, making validation of numeric but
not-only-int values more complicated for the user.
this commits implements the options min_range and max_range for the function
php_filter_float to fix this inconsistency.

If PREG_UNMATCHED_AS_NULL is used, make sure that unmatched capturing
groups at the end are also set to null, rather than just those in the
middle.

Fixed bug #72685

We currently have a large performance problem when implementing lexers
working on UTF-8 strings in PHP. This kind of code tends to perform a
large number of matches at different offsets on a single string. This
is generally fast. However, if /u mode is used, the full string will
be UTF-8 validated on each match. This results in quadratic runtime.

This patch fixes the issue by adding a IS_STR_VALID_UTF8 flag, which
is set when we have determined that the string is valid UTF8 and
further validation is skipped.

A limitation of this approach is that we can't set the flag for interned
strings. I think this is not a problem for this use-case which will
generally work on dynamic data. If we want to use this flag for other
purposes as well (mbstring?) then it might be worthwhile to UTF-8 validate
strings during interning. But right now this doesn't seem useful.
