When doing a firmware (radio or hboot) update on HTC devices, save the
recovery log in block 1 of the cache partition, before the firmware
image and the UI bitmaps. When we boot back into recovery after the
firmware update to reformat the cache partition, copy that log out of
cache before reformatting it and dump it into the current invocation's
log.
The practical upshot of all this is that we can see the log output
from radio and hboot updates.

Change the recovery UI so that when there is a hboot or radio update
pending (which the user most do a home+back reboot to actually
install), the UI tells them so, instead of saying "Install from sdcard
complete."
