Merge "Add slot_suffix field to struct bootloader_message."

 * multiple times, so that the UI can reflect which invocation of the

 * package it is.  If the value is of the format "#/#" (eg, "1/3"),

 * the UI will add a simple indicator of that status.

 *

 * The slot_suffix field is used for A/B implementations where the

 * bootloader does not set the androidboot.ro.boot.slot_suffix kernel

 * commandline parameter. This is used by fs_mgr to mount /system and

 * other partitions with the slotselect flag set in fstab. A/B

 * implementations are free to use all 32 bytes and may store private

 * data past the first NUL-byte in this field.
