What's new in this version:

Changes/fixes:
- Implemented the bulk of the CSS "cascade layers" spec (@layer{}). This implementation is not 100% complete yet, but should satisfy common use of CSS cascade layers on the web.
- Implemented support for Sec-Fetch-* headers, implementing another mechanism to deal with site security. See this part of the spec for a primer on what this does.
- Added support for FFmpeg 7.0 / libavcodec 61 (Linux).
- Pale Moon will now look up hosts in DNS ahead of time to make page navigation smoother. See implementation notes.
- Pale Moon will now block access to the reserved address 0.0.0.0 on non-Windows operating systems. See implementation notes.
- Dev: Aligned rounding behavior and precision ranges of toFixed and related functions with the spec. See implementation notes.
- Dev: Aligned isTrusted for PostMessage and BroadcastChannel with expected values on the web. See implementation notes.
- Dev: Added the navigator.webdriver attribute for web compatibility (always false in Pale Moon as we do not support browser automation APIs).
- Re-implemented the Durstenfeld shuffle for plugin enumeration that was unfortunately dropped with one of our past rebases, to strengthen fingerprinting resistance.
- Fixed an issue with character clusters (e.g. for text selection) resulting from a regression surrounding our improvements for emoji handling
- Fixed an issue with setting DOM color values
- Slightly improved password form handling, detecting previously unsupported field orders
- Updated NSS to 3.90.4
- Updated our emoji font to 15.1.2 (Unicode 15.1 with some additional extras/updates)

Code cleanup:
- Removed unused code related to the (incomplete) FoxEye experiment
- Removed support code for LibAV and (very) old versions of FFmpeg. We require libavcodec 58 or later (FFmpeg 4.0+) from this version forward (Linux).
- Removed click event dispatching code that is no longer relevant
- Cleaned up internal macro use in CSS code (this does not impact any exposed APIs or code)
- Removed the hidden network.dns.disablePrefetchFromHTTPS pref. DNS prefetching should not be treated differently for http and https
