This allows writing
array_merge(...$arrays)
instead of
array_merge([], ...$arrays)
and is in line with similar changes to array_push() and array_unshift()
in PHP 7.3.
Closes GH-4175.
`curl_version()`[1] (of ext/curl) makes `curl_version_info()`[2] (of
libcurl) available to PHP userland. The latter requires to pass an
`age` argument which usually is `CURLVERSION_NOW`, so that the
information returned by the runtime matches the declarations used
during compile time. For C programs it is simply necessary to pass
this information, and in rare occasions it might make sense to pass
something else than `CURLVERSION_NOW`. curl.h notes:
| The 'CURLVERSION_NOW' is the symbolic name meant to be used by
| basically all programs ever that want to get version information.
For the PHP binding, using a newer `age` than available at compile time
will neither provide the PHP program more information, nor would using
an older `age` have tangible benefits.
We therefore deprecate the useless `$version` parameter, and if it is
passed nonetheless, we use `CURLVERSION_NOW` instead of the supplied
value, and raise a warning.

Make sure to always fetch the RHS of a list assignment first, instead
of special casing known self-assignments, which will not detect cases
using references correctly.
As a side-effect, it is no longer possible to do something like
byRef(list($x) = $y). This worked by accident previously, but only
if $y was a CV and the self-assignment case did not trigger.
However it shouldn't work for the same reason that byRef($x = $y)
doesn't. Conversely byRef(list(&$x) = $y) and byRef($x =& $y)
continue to be legal.
`CURLPIPE_HTTP1` is deprecated and has no effect as of cURL 7.62.0[1].
We therefore deprecate the PHP constant as well, and trigger a warning
that it is no longer supported, if used against cURL 7.62.0 and up.

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.

Arbitrary DateInterval objects don't have well-defined comparison
semantics. Throw a warning and treat the objects as uncomparable.
Support for comparing DateInterval objects returned by
DateTime::diff() may be added in the future.
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.
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.
This variant of crc32 is heavily used by storage systems, such as iSCSI, SCTP,
Btrfs, ext4, and is increasingly being used in API (such as Google Cloud
Storage, and Apache Kafka).
This reverts commit a9e6667817.
Breakage found in the wild: Mockery uses a parent:: call in the
implementation regardless of whether the class has a parent or not:

This change is not worth the compat break in 7.4.
This code is not compatible with PHP 7.0. The fact that nobody
complained that the mysqli embedded server functionality doesn't
build anymore seems like a strong signal that we can drop it...
Do not include unbound anonymous classes in get_declared_classes().
Note that earlier PHP versions would include the anonymous class in
get_declared_classes(), and return false until the class was bound,
but would not crash.
As of PHP 7.3.0, case-insensitive constants are deprecated. We catch
up on this with regard to ext/com_dotnet, which allows to import
constants from typelibs, by triggering a deprecation notice whenever
`com_load_typelib()` is called with `$case_sensitive` being `false`,
and whenever `com.autoregister_casesensitive` is set to `false`,
regardless of whether there are actually constants in the typelib which
would be imported.
SO_USER_COOKIE primarly to be traced via dtrace instrumentation.
If SO_USER_COOKIE is available, the rest is so the former is
two years old while the rest is from around 2008.
