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.

Payloads created using Serializable are still supported.

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.

Implement new custom object serialization mechanism

RFC: https://wiki.php.net/rfc/custom_object_serialization

Fix bug #73948

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.

Sync the changes to ext/filter with 7.4, now that it works.

- Removed --with-pcre-dir
- The filter extension can now be built as shared on Unix with ./configure

Unbundle ext/wddx

The extension is now available from <https://pecl.php.net/package/wddx>.

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.

Revert "Detect invalid uses of parent:: during compilation"

This reverts commit a9e6667817c38f22f4645ec5b4e5c6b0e4b928fa.

Breakage found in the wild: Mockery uses a parent:: call in the
implementation regardless of whether the class has a parent or not:
https://github.com/mockery/mockery/blob/4324afeaf9d95b492507e6587abb3f024e2576de/library/Mockery/Mock.php#L600

This change is not worth the compat break in 7.4.
