It was pointed out to me by gmrt that O_APPEND is incorrect, as lseek
before writing would be undone (perhaps we avoided this issue due to
an inability to write beyond the end of a partition) and O_RDWR is not
necessary to lseek. When AOSP switched from fopen to open, they also
removed the full partition wipe (fopen in wb mode) before each write,
so this is no longer an issue. Completely restore the original AOSP
file access mode flags.

Globally define BOARD_RECOVERY_BLDRMSG_OFFSET with a decimal integer
to offset the read/write location in misc where the bootloader message
should appear. Example:
BOARD_GLOBAL_CFLAGS := -DBOARD_RECOVERY_BLDRMSG_OFFSET=2048
Edify commands get_stage and set_stage need to be aware of the
custom bootloader msg offset because they write the stage directly
to the BCB.

* 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!

bootloader_messages merges bootloader_message_writer
and bootloader.cpp, so we can use the same library to
manage bootloader_message in normal boot and recovery mode.
