(This is being cherry-picked from master.)
hboot will apparently fail to install if the first block of the image
(the one pointed to by the offset in the block 0 header) is a bad
block. (Hopefully it handles subsequent bad blocks.)
This change makes the MTD write code keep track of the bad blocks it
has skipped over, so that the offset in the header can be adjusted to
be the address of the first successfully written block.

When using the hidden menu to wipe data in recovery, confirm before
starting the wipe. (This does not affect booting with the --wipe_data
flag, or using Alt+W on dream with the menu hidden -- those still wipe
data immediately.)
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.
The symlink() function should remove existing files before creating
symlinks, so scripts are idempotent. Log messages when various system
calls fail (but don't make the whole script fail).
If the a recovery icon file is so short that we can't even read the
8-byte header, put a message in the log but not on the device screen.
We intentionally have zero-length files for some icons on some devices,
if they're never shown (eg, the firmware installation icons are only
used on HTC devices).
With the recovery image being installed by applypatch, the flash_image
tool isn't needed any more. Continue to build it for eng just in case
it's handy for debugging.
gcc 4.4 complains about some of the recovery ui functions not being
declared. To include the header, we have to fix the 'volatile'
declaration (otherwise there's a compiler error).
Move the dream-specific images to vendor/htc/dream, make the default
images a generic phone.
Yank all the code to install OTA packages out of the recovery binary
itself. Now packages are installed by a binary included in the
package (run as a child of recovery), so we can make improvements in
the installation process without waiting for a new release to use
them.
We fail to detect certain bad blocks (marked in the factory as bad, I
think?) when reading mtd partitions. These come back as a block of
all zeros. Since it's fairly unlikely a legitimate boot or recovery
block will contain 128k of zeros, change mtdutils to skip over such
blocks.
Arve says https://review.source.android.com/10535 may be a long-term
fix for this, but he isn't yet sure.
updater (which is only needed in OTA packages) is getting included in
/system/bin, where it just takes up (quite a bit of) space. Use the
hack of including it only in eng builds so it's not there for user
builds.
Let recovery accept set_progress commands to control progress over the
'current segment' of the bar. Add a set_progress() builtin to the
updater binary.
Allow devices (in BoardConfig.mk) to define additional static
libraries to be linked in to updater, to make device-specific
functions available in edify scripts. Modify the updater makefile to
arrange for device libraries to register their edify functions.
Some devices want to do special things when recovery wipes data (eg,
wipe data in their baseband processor as well). Add a hook in the
device-specific recovery library that gets called when data is wiped.
Also add an amend root for the "mbm" partition.
Add a function to read a property from a ".prop"-formatted file
(key=value pairs, one per line, ignore # comment lines and blank
lines). Move ErrorAbort to the core of edify; it's not specific to
updater now that errors aren't stored in the app cookie.
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.

edify extensions for OTA package installation, part 2
Add functions less_than_int() and greater_than_int() that interpret
their args as ints and do the comparison. ("<" and ">" operators, if
implemented, should do string comparison.) This lets us do the build
time check currently done by the check_prereq binary.
A few more changes to edify:
- fix write_raw_image(); my last change neglected to close the write
context, so the written image was corrupt.
- each expression tracks the span of the source code from which it
was compiled, so that assert()'s error message can include the
source of the expression that failed.
- the 'cookie' argument to each Function is replaced with a State
object, which contains the cookie, the source script (for use with
the above spans), and the current error message (replacing the
global variables that were used for this purpose).
- in the recovery image, a new command "ui_print" can be sent back
through the command pipe to cause text to appear on the screen.
Add a new ui_print() function to print things from scripts.
Rename existing "print" function to "stdout".
Adds more edify functions for OTAs:
is_mounted getprop apply_patch apply_patch_check apply_patch_space
write_raw_image write_firmware_image package_extract_file
This allows us to install radios, hboots, boot images, and install
incremental OTA packages.
Fixes a couple of dumb bugs in edify itself:
- we were doubling the size of the function table each time it was
*not* full, rather than each time it was full
- "no such function" errors weren't visible to the parser, so they
didn't prevent execution of the script.

edify extensions for OTA package installation, part 1
Adds the following edify functions:
mount unmount format show_progress delete delete_recursive
package_extract symlink set_perm set_perm_recursive
This set is enough to extract and install the system part of a (full)
OTA package.
Adds the updater binary that extracts an edify script from the OTA
package and then executes it. Minor changes to the edify core (adds a
sleep() builtin for debugging, adds "." to the set of characters that
can appear in an unquoted string).
Take some device-specific details of the recovery UI (eg, what keys to
press to bring up the interface and perform actions, exact text of the
menu, etc.) and split them out into separate C functions. Arrange to
take implementations of those functions from the appropriate vendor
directory at build time. Provide a default implementation in case no
vendor-specific one is available.
