v0.14.1.AA

Synced with Upstream v0.14.1
Adds SyncTrust Feature
- The boot Chain of Trust may be broken on booting with 3rd-party tools on T2/TPM chipped units
- When this happens, the unit refuses to boot the selected item and may even become unresponsive
- This feature provides a workaround by triggering a trusted native reboot to the selected item
- This feature can be enabled by activating a new sync_trust configuration token
Adds LegacySync Feature
- RefindPlus previously assumed all Macs were capable of legacy BIOS boot
  - This was from code that went in upstream in 2012 when this was a reasonable working assumption
    - However, Macs later became UEFI certified and the last Intel Macs appear to be UEFI Class 3+
    - UEFI Class 3/3+ devices do not support legacy BIOS boot
  - This feature attempts to categorise Macs and allow/disallow legacy BIOS boot accordingly
- Enabled by default but can be disabled using a new disable_legacy_sync configuration token
  - Disabling might be needed if a Mac is mis-categorised and legacy BIOS boot wrongly prevented
Adds HelpSize Feature
- Provides option to force non-standard or otherwise unsupported screen resolutions
  - This can help work around issues where pre-boot configuration screen are not displayed
  - The issues are typically EDID related or the auto-selection of incorrect/incompatible resolutions
  - This aspect of the HelpSize feature requires booting into systems that fully support the graphics
- An ExDPI category for screens with resolutions of 6400 x 4000 or more was created
  - UI elements are scaled up by four (4) on such screens when UI element scaling is active
  - UI elements on other HiDPI screens are still scaled up by two (2) with UI scaling active
- Enabled by default but can be disabled using a new decline_help_size configuration token
  - The new token sets RefindPlus to only apply up to 2x UI element scaling
Fixes Legacy BIOS Boot on Certified UEFI Class 2 Macs
- Optimisations for speed had potentially disabled legacy BIOS boot on some Macs
- This bug was introduced in v0.13.3.AB (Commit 66dbed0)
Fixes Potential Memory Conflict
- Some constants were passed to a function that reallocates memory
- This bug was introduced in v0.14.0.AA (Commit 3fc36f5)
- Extended in v0.14.0.AB (Commit 5cb1ed9)
Fixes Display Resolution Handling
- User defined resolutions were not being properly handled
  - Only the default, max, resolution was considered
  - This meant that instances with defined resolutions were not properly displayed
- Separately, the selected resolution when seeking max was not always the actual maximum
- Additionally, a HelpSize Feature, documented separately, was introduced
Fixes DirectBoot Handling
- Was not functional
Fixes HelpScan Handling
- Rationalises implementation
  - Could be applied, when disabled, to some items that should be excluded
Improves SystemdVars Handling
- The LoaderDevicePartUUID UEFI Variable is written to vRAM and not nvRAM
- See: https://sf.net/p/refind/discussion/general/thread/d8dad2c475/
Improves GraphicsFor Handling
- Users can now set none under the use_graphics_for token to disable graphics mode boot
- Users can now set everything to activate this for all boots
  - The previous option of setting use_graphics_for alone has also been fixed and remains
Improves HiddenTags Handling
- Shows volumes names along with GUID where only the GUID would have previously been shown
  - Allows human friendly instance identification when viewing the Restore Entries screen
- Breaks backward compatibility with upstream when tags are hidden in RefindPlus
  - Tags hidden upstream remain forward compatible with RefindPlus
- Fixes situation where some loaders in ESP locations were not hidden when selected on-screen (minus key)
  - Was also the case when full paths were used in dont_scan_files
Improves License Presentation
- Rationalises presentation to make clear it is on GPLv3/Later
Improves MemTest Handling
- Updated exclusion from loaders (Row 1 Items)
- Updated to handle memtest+{ARCH}.efi and memtest86+{ARCH}.efi files as per upstream
Improves ProtectNvram Handling
- Now also blocks the CurrentPolicy and CurrentActivePolicy variables
Improves SyncNVram Handling
- Now also clears the opencore-version variable, if present, when booting into macOS directly
  - This variable is effectively an OpenCore Present flag that is checked by the macOS kernel
  - This variable removal only applies when RefindPlus is NOT chain-loaded via OpenCore
  - This variable removal also applies to macOS installers
- Separately, the implementation of the base feature was not functional on macOS boots and was fixed
Improves HelpIcon Handling
- The following OS Icons are now cached on first load and reused as required afterwards when this feature is active
  - List is "os_mac", "os_win", "os_win8", "os_linux", "os_legacy", "os_clover", "os_opencore", "os_unknown", and "dummy image"
  - List is stored in TableBuiltinIconOS
- Supplements the existing caching of items covered by BuiltinIconTable
  - The BuiltinIconTable item caching always happens with or without the HelpIcon feature
Improves CleanNvram Handling
- Now clears CurrentPolicy and CurrentActivePolicy variables on Apple firmware
Improves Misc Handling
- Restructured config file into four (4) sections
- Completed LodePNG 20230410 update started in v0.14.0.AC
- Renames the cd item under the scanfor config token as cdbios
  - Provides clarity that this is a BIOS scan option
  - Maintains compatibility with existing settings including upstream
- The TimeoutSeconds item in REFIT_MENU_SCREEN was changed to INTN
  - Follow on from fix to Timeout item in REFIT_CONFIG previously changed to INTN
  - The original fix for SilentBoot/DirectBoot was incomplete (Commit 78d6138 in v0.13.2.AH)
- Applied misc micro optimisation for speed
  - Restructured search pattern for config tokens
  - Optimised LoadDrivers function
- Misc fixes for running in TextOnly mode
- Adjusted AppleFramebuffer handling to eliminate unneeded cycles
Renames Misc Configuration Tokens
- disable_amfi to disable_check_amfi
- disable_compat_check to disable_check_compat
