Previously, the URL validator accepted all kinds of URLs.
Combining it with other validators like `Domain` and `Ip` manually
is clumbersome, since the rules are extensive and require small
tweaks such as understanding bracketed IP addresses.
This change makes that composition built-in. The validator still
uses the FILTER_VALIDATE_URL from PHP, but now it also goes deeper
and validate portions of the URL that other validators support.
Changes to `Call` were made so that it can be serialized under
certain circumstances (when invoking a static method call), making
it more flexible.
A static internal method helper for trimming the IP was added to
the Url validator class and marked as internal, as it cannot be
both private, serializable and accessible to the `Call` instance
all at the same time. The `@internal` annotation should advise
users that it's not a public API according to phpdoc conventions.
This commit introduces REUSE compliance by annotating all files
with SPDX information and placing the reused licences in the
LICENSES folder.
We additionally removed the docheader tool which is made obsolete
by this change.
The main LICENSE and copyright text of the project is now not under
my personal name anymore, and it belongs to "The Respect Project
Contributors" instead.
This change restores author names to several files, giving the
appropriate attribution for contributions.
