Split out core functionality into separate module #1664

Prerequisites

• I verified that this is not a filter issue (MUST be reported at filter issue tracker)
• This is not a support issue or a question
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
• The issue is not present after wholly disabling uBlock Origin ("uBO") in the browser
• I checked the documentation to understand that the issue I report is not a normal behavior

I tried to reproduce the issue when...

• uBO is the only extension
• uBO with default lists/settings
• using a new, unmodified browser profile

Description

I have just updated the Cliqz benchmarks with the latest versions of Adblock Plus (ghostery/adblocker@a2da894) and Brave (ghostery/adblocker@97dc7c1)

Unfortunately it's not trivial to do the same for uBlock Origin, because of the relative tight coupling in the code. In fact, it keeps getting harder. For example, uritools.js now refers to the vAPI object whereas previously it did not.

It would be ideal if the core filter parsing, matching, and serialization functionality were split out into a separate Node.js module.

Steps to Reproduce

Try to update the benchmarks at https://github.com/cliqz-oss/adblocker/tree/master/packages/adblocker-benchmarks with the latest version of uBlock Origin.

Expected behavior

It should be as easy as updating a version number or a commit hash in the package.json file in that repo.

Actual behavior

It's too much work that involves copying and modifying a bunch of files from the uBlock Origin repo.
