Migrate SKIPIF -> EXTENSIONS (#7138)

This is an automated migration of most SKIPIF extension_loaded checks.

Update ext/phar parameter names

Closes GH-6307.

Make Phar $format and $compression arguments nullable

Rather than using Greg's birthday, use null to indicate that the
existing format/compression should be retained. For the format

Make Phar $format and $compression arguments nullable

Rather than using Greg's birthday, use null to indicate that the
existing format/compression should be retained. For the format
simply using zero would be sufficient, but as the documentation
explicitly says that NULL is allowed here, we may as well make
that the truth.

Improve error messages mentioning parameters instead of arguments

Closes GH-5999

Make null byte error a ValueError

Currently we treat paths with null bytes as a TypeError, which is
incorrect, and rather inconsistent, as we treat empty paths as
ValueError. We do t

Make null byte error a ValueError

Currently we treat paths with null bytes as a TypeError, which is
incorrect, and rather inconsistent, as we treat empty paths as
ValueError. We do this because the error is generated by zpp and
it's easier to always throw TypeError there.

This changes the zpp implementation to throw a TypeError only if
the type is actually wrong and throw ValueError for null bytes.
The error message is also split accordingly, to be more precise.

Closes GH-6094.

Fix UNKNOWN default values in various extensions

Closes GH-6075

Display nullability in type error messages for internal functions

Closes GH-5327

Change argument error message format

Closes GH-5211

Make type error messages more consistent

Closes GH-5092

Reindent phpt files

Clean DONE tags from tests

Remove most of the `===DONE===` tags and its variations.
Keep `===DONE===` if the test output otherwise becomes empty.

Closes GH-4872.

Merge branch 'PHP-7.4'

* PHP-7.4:
Replace dirname(__FILE__) by __DIR__ in tests

Replace dirname(__FILE__) by __DIR__ in tests

Adjust tests for zpp TypeError change

remove support for string|unicode in tests

Use int instead of integer in type errors

PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".

Fix bug #71860: Require valid paths for phar filenames

Updated tests to reflect exception class changes.

Always throw TypeException on throwing zpp failures

Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to
report FAILURE errors using a TypeException instead of a Warning,

Always throw TypeException on throwing zpp failures

Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to
report FAILURE errors using a TypeException instead of a Warning,
like it would happen in strict mode.

Adds a zend_parse_parameters_throw() convenience function, which
invokes zpp with this flag.

Converts all cases I could identify, where we currently have
throwing zpp usage in constructors and replaces them with this API.
Error handling is still replaced to EH_THROW in some cases to handle
other, domain-specific errors in constructors.

Patch improvement:

Removed the corresponding core code.
Fixed ext/com_dotnet and ext/date.
Refactored ext/intl changes.
Improved ext/fileinfo and ext/pdo changes.
Fixed tests.

Use "float" and "integer" in typehint and zpp errors

- Unifiy that message
- Mention php.ini

mention which setting!

merge unmerged changes between branches, remove unnecessary test for zip signature failure in badparameters.phpt

- Bring phar tests into line across all branches
