It is is sometimes desired to be able to skip decrementing the number of
tries remaining in an Android A/B boot, and instead just check which
slot will be tried later. This can commonly be be the case for platforms
that want to A/B u-boot itself, but are required to boot from a FAT MBR
partition. In these cases, u-boot must do an early check that the MBR
points to the correct A/B boot partition, and if not rewrite the MBR to
point to the correct one and reboot. Decrementing the try count in this
case is not desired because it means that each u-boot might constantly
ping-pong overwriting the MBR and rebooting until all the retries are
used up.

This adds an option to part_get_info_by_dev_and_name_or_num to allow
callers to specify whether whole-disk partitions are fine.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

We should not be using typedefs and these make it harder to use
forward declarations (to reduce header file inclusions). Drop the typedef.

For A/B system update support the Android boot process requires to send
'androidboot.slot_suffix' parameter as a command line argument. This
patch implementes 'ab_select' command which allows us to obtain current
slot by processing the A/B metadata.
The patch was extracted from commit [1] with one modification: the
separator for specifying the name of metadata partition was changed
from ';' to '#', because ';' is used for commands separation.
