Create bootloader_message static library.
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.

-/* Bootloader Message
- *
- * This structure describes the content of a block in flash
- * that is used for recovery and the bootloader to talk to
- * each other.
- *
- * The command field is updated by linux when it wants to
- * reboot into recovery or to update radio or bootloader firmware.
- * It is also updated by the bootloader when firmware update
- * is complete (to boot into recovery for any final cleanup)
- *
- * The status field is written by the bootloader after the
- * completion of an "update-radio" or "update-hboot" command.
- *
- * The recovery field is only written by linux and used
- * for the system to send a message to recovery or the
- * other way around.
- *
- * The stage field is written by packages which restart themselves
- * 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.
