For some usecases it is desired to still update the GPT headers even if
the UFS BSG device is missing. Add a new flag which implements this
behaviour.
It isn't made the default because on some platforms this could result in
an unbootable device, there it's preferable to defer to the user by just
bailing out if the UFS BSG device is unavailable.

The only C++ was for handling discovering and iterating over the
partitions PER block device, this was implemented in a really
overcomplicated way.
Simplify things, port everything over to c11 and drop the libstdc++
requirement entirely.
Allocate gpt_disk on stack, allocate when needed, rather than multiple
times for every partition.
Huge code cleanup, rerun clang-format, etc
Many changes here inspired by Eric's earlier work.
This commit introduced a lot of changes and seems to have caused a few
issues, including breaking crc32 generation. Revert it for now with the
intention to reimplement some of the improvements.
This reverts commit 9d7600df51.
If we are using C++, we might as well use scope-based memory management
for these things, cleaner and less error prone. Also removed
unnecessary gotos.
getting attributes work, setting them (e.g. with mark_boot_successful)
doesn't seem to work properly.
The IOCTL required to set the boot LUN doesn't work, some kernel driver
is missing for it.
This is a port of the Android bootctrl HAL and Qualcomms GPT based
implementation for musl/glibc based systems running mainline linux
Currently it doesn't work because the gpt hdr which is read doesn't
seem to have valid data.
