Add new static network filter option: `urltransform`
The `urltransform` option allows to redirect a non-blocked network
request to another URL. There are restrictions on its usage:

- require a trusted source -- thus uBO-maintained lists or user
  filters
- the `urltransform` value must start with a `/`

If at least one of these conditions is not fulfilled, the filter
will be invalid and rejected.

The requirement to start with `/` is to enforce that only the path
part of a URL can be modified, thus ensuring the network request
is redirected to the same scheme and authority (as defined at
https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax).

Usage example (redirect requests for CSS resources to a non-existing
resource, for demonstration purpose):

    ||iana.org^$css,urltransform=/notfound.css

Name of this option is inspired from DNR API:
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/declarativeNetRequest/URLTransform

This commit required to bring the concept of "trusted source" to
the static network filtering engine.

How to build MV3 uBO Lite

Instructions for reviewers.

The following assumes a linux environment.

  1. Open Bash console
  2. git clone https://github.com/gorhill/uBlock.git
  3. cd uBlock
  4. make mv3-[platform], where [platform] is either chromium or firefox
  5. This will fully build uBO Lite, and during the process filter lists will be downloaded from their respective remote servers

Upon completion of the script, the resulting extension package will become present in:

  • Chromium: dist/build/uBOLite.chromium
  • Firefox: dist/build/uBOLite.firefox

The folder dist/build/mv3-data will cache data fetched from remote server, so as to avoid fetching repeatedly from remote server with repeated build commands. Remove dist/build/mv3-data if you want to build with latest versions of filter lists.

The file dist/build/mv3-data/log.txt will contain information about what happened during the build process.

The entry in the Makefile which implement the build process is tools/make-mv3.sh [platform].[1] This Bash script copy various files from uBlock Origin branch and MV3-specific branch into a single folder which will be the final extension package.

Notably, tools/make-mv3.sh [platform] calls a Nodejs script which purpose is to convert the filter lists into various rulesets to be used in a declarative way. The Nodejs version required is 17.5.0 or above.

All the final rulesets are present in the dist/build/uBOLite.[platform]/rulesets in the final extension package.
