Remove support for the HTC-specific "firmware" update command and the
corresponding edify function write_firmware_update(). This
functionality is now done by an edify extension library that lives in
vendor/htc.

Reduce the fraction of the progress bar used for package verification
from 50% to 25%:
- verification is faster than before due to sha1 improvements
- in eclair we're now verifying the compressed data rather than
decompressing it
- incremental packages (which is what most installs use) write more
data than is contained in the package.
To do a firmware-install-on-reboot, the update binary tells recovery
what file to install before rebooting. Let this file be specified as
"PACKAGE:<foo>" to indicate taking the file out of the OTA package,
avoiding an extra copy to /tmp. Bump the API version number to
reflect this change.
