Releases for Advanced CSS/JS Aggregation

PHP 8.1/Drupal 10 support
Tests are passing, but many more tickets to go through before a stable release.

Two submodules - CDN and Old IE have been removed. DB updates are included but if you have modules depending on those this will be a breaking change.

#2973383: Cascading rename options by mikeytown2, ron_s

The drupal/advagg:4.0 needs drupal (>= 8.6)

Bugs Fixed:
#2941500: Some external scripts that should be async are not async
#2942204: Incorrect URLs formed when using critical CSS leading to 404s

Bugs Fixed:
#2932743: Update font parser to work with all quoted fonts; also display fonts that can't be asynced due to no fallback.

Bugs Fixed:
#2919748: CSS file controlled deferring affects every page
#2920184: Piwik JS does not run with AdvAgg active

The only significant change here is the addition of the advagg_bundler sub module to the 8.x-3.x branch. It is ready for use with all the same functionality as in 8.x-2.x (and 7x).
Also, quite a few bug fixes. Thanks everyone for the reports, testing and discussion.

All changes since 8.x-3.3:

Known Issues:
#2912888: CSS Minification - Fatal error: Cannot redeclare class CSSmin.
#2907586: Adminimal Administration Menu breaks display for Deferred JavaScript Execution option

New Features:
- Include external CSS/JS in local aggregates.
- Add JS to blocks, views, etc via scope key.
- If inline CSS is critical, set 'critical-css' key to TRUE and advagg will load the rest of the css via javascript.
#2886940: Aggregate External CSS & JS

Compatible with Drupal core 8.0.x-8.4.x
Installation Instructions:
If a new site just install as normal.
If upgrading from an old install, delete the old module files as some files have been removed/renamed etc. (Not required if using Composer/Drush as they do that automatically prior to upgrading any package). Also make sure to run the database updates (drush updb or update.php).

Pretty major re-factor in the underlying code and methodology, however very similar in terms of actual functionality and user interaction.
Primary differences:

Bugs Fixed:

#2853967: Error in advagg_bundler_get_css_selector_count - missing ctools css

Bug fixes (thanks for the patches and reports everyone). Also only of interest to developers, a bunch of documentation improvements & a few standards fixes.
One issue to note is that this branch is currently incompatible with Drupal 8.3.x. We'll try to have that fixed before the end of this month - see #2850263: PHP Fatal error on CacheCollector.php.

Changes since 8.x-2.0:

Broken do NOT use.

Bugs Fixed:
#2698793: some ga( calls fail if Deferred inline JavaScript Execution: Put a wrapper around inline JS so it runs from a setTimeout call is enabled

Stability has improved slightly as well as various fixes and improvements. The most significant change from RC1 is the addition of a migration path from AdvAgg 7.x-2.x so now when running an upgrade you can also upgrade your AdvAgg settings. Do note that due to various differences not all settings are equivalent so you reviewing after import is recommended.
Thanks to toomanypets, Sam152, alexpott, kiamlaluno, heykarthikwithu, dscoop and everyone else for the patches/testing/reports/suggestions.

Known Issues:
#2697079: Bootstrap JS broken with JSqueeze

First beta.
Should be stable and functional although it needs more testing (that's where you come in ;) ). Documentation and automated testing is in poor shape (read: needs doing urgently). Feature wise it is fairly equivalent to the D7 branch other than changes mandated by the D8 architectural changes. Advagg_font submodule is not yet ported.

Bugs Fixed:
#2576381: CSS aggregation is broken by files encoded in UTF8 with BOM
#2604828: Handling of protocol relative urls
