* Rebase of https://gerrit.omnirom.org/#/c/20750/ patch-set 3 * Original commit message: fix: recently a change in AOSP causes a bootloop to TWRP (and therefore all ROM's based on it) Reason: AOSP enables use of /misc partition and normally the fstab in TWRP will not have /misc added. The problem is now when Android writes a wipe command to /misc it will force TWRP to boot but TWRP will do nothing - leaving the cmd in /misc. This results in a bootloop to TWRP. Solution: I added a new var TW_IGNORE_MISC_WIPE_DATA which can be set to "true" in Boardconfig.mk of a device requiring this which then ignores /misc commands like it would be when /misc would be just not in fstab BUT with this change TWRP clears the bit in /misc so a normal boot can happen. Besides that if the device do not have an own recovery key combo and /misc is enabled we want to open TWRP after walking through the factory reset screen - without actually doing a factory reset. kudos to nailyk (and DevUt) for the help with the C++ code!
