Most of the functionality provided by this tool (typically the
validation and actual deployment of the plugin package) has been moved
to the core level. So this is becoming just a thin wrapper and user
interface for installing new plugins via the administration UI.
Also fixes MDL-49600 as we no longer keep the unzipped contents of the
packages in the persistent temp directories.
This is not really new class. Originally, the validator was implemented
in the scope of the tool_installaddon plugin. But we need its features
in other parts at the core level (e.g. during the upgrade to validate
available missing dependencies or available updates). Looking back, it
was a mistake to have it implemented at the plugin level rather than the
core level.
So this patch moves the tool_installaddon_validator class to
\core\update\validator class, together with associated unit tests,
fixture files and strings. There were changes made in the
tool_installaddon to make use of this new class instead of the old one.
This is a great step towards the bright future, hopefully there won't be
many regressions.

On contrary to deeper heuristic (read: guessing) we perform in the
Plugins directory (such as looking at the names of the language files),
here we simply rely on the plugin component being correctly defined in
the version.php file.
The validator class has more robust processing, to make sure the
component declaration is not provided in a commented area of the
version.php etc. However, as it is fully acceptable that the
auto-detection fails if the version.php uses non-standard syntax, this
easier approach is valid here.
Better performance, more reliable, completely self contained,
more validation and full backwards compatibility.
This will also allow us to implement ignoring of plugins.
The native rename() function does not support moving folders
cross-device. See https://bugs.php.net/bug.php?id=54097 for details. So
instead of trying to move the whole tree, the new installer's method
moves files recursively one by one.
This is consistent with what mdeploy.php already does.
There is a new hook in the index.php file. If valid HTTP parameter
installaddonrequest is detected, the installer asks the administrator to
confirm the request.
If confirmed, the installer calls download.moodle.org/api/1.2/pluginfo.php
service to get information about the given plugin version. The essential
data are the URL of the ZIP to download and the MD5 hash of the ZIP.
These data must be fetched via HTTPS to protect against MiM attack.
If the ZIP is downloaded and the MD5 content hash is correct, the user
is redirected to the previously implemented ZIP validation page, as if
the ZIP was uploaded manually.
The valid format of the installaddonrequest is documented via the
test_decode_remote_request() unit test method.
