Failures are seen on devices with
Linux 3.10. And they are mainly due to this change:

The blocks reserved in this change is not the same thing as what we
think are reserved for common usage of root user. And this part is
included in free blocks but not in available blocks.

We have seen cases where the boot partition is patched, but upon
recovery the partition appears to be corrupted. Open up all
patched files/partitions with O_SYNC, and do not ignore the
errors from fsync/close operations.

Patches with control data tuples with negative numbers in the first
and/or second can cause bspatch to write to arbitrary locations in the
heap.

Older versions of android supported an ASLR system where binaries were
randomly twiddled at OTA install time. Remove support for this; we
now use the ASLR support in the linux kernel.

These were attempts to write partitions "conservatively" in hopes of
fixing the problems with writing the radio partition on Nexus 4. They
didn't work (a kernel patch was needed), but got left in. They make
writing of partitions unnecessarily slow (ie, we really shouldn't need
to sync() after every 4kb). Roll back most of them, but leave the
verification read-back in.

Write and verify partitions using write(2) and read(2) rather than the
stdio functions. Read and write in 4kb blocks. When writing, fsync()
every 1MB.

Nexus 4 has flash errors that manifest during large writes (eg, of the
radio partition). Writes of some blocks seem to be dropped silently,
without any errors being returned to the user level.
Make two changes to the partition-writing code:
- break it up into 1MB writes instead of writing partitions with a
single fwrite() call. Pause for 50ms in between every chunk.
- read the partition back after writing and verify that we read what
we wrote. Drop caches before reading so we (hopefully) are reading
off the actual flash and not some cache.
Neither of these should be necessary.

Make minzip log only a count of files when extracting, not individual
filenames. Make patching only chatter about free space if there's not
enough and compact the other messages.
Only the last 8k of the recovery log gets uploaded; this makes it more
likely that we will get all of it.

The bonus data option lets you give an additional blob of uncompressed
data to be used when constructing a patch for chunk #1 of an image.
The same blob must be available at patch time, and can be passed to
the command-line applypatch tool (this feature is not accessible from
edify scripts).
This will be used to reduce the size of recovery-from-boot patches by
storing parts of the recovery ramdisk (the UI images) on the system
partition.

When creating a new file using open(..., O_CREAT), it is an error
to fail to specify a creation mode. If a mode is not specified, a
random stack provided value is used as the "mode".
This will become a compile error in a future Android change.

The applypatch function is somewhat sloppy about freeing memory (since
it was originally a standalone binary). Fix some of that.

An accidental variable declaration ("int enough_space = ..." instead
of "enough_space = " inside a block) shadowing the real one meant we
were always using the copy-to-cache path for patching, even when not
necessary. Remove it. Enforce an absolute minimum of free space as
well, to avoid running into problems patching small files, now that
the copy-to-cache path is (inadvertently) well-tested.

When restarting a patch from crashing in the middle of a large file,
we're not finding the correct patch to apply to the copy saved in
cache.

Separate files for retouch functionality are in minelf/*
ASLR for shared libraries is controlled by "-a" in ota_from_target_files.
Binary files are self-contained. Retouch logic can recover from crashes.

Let applypatch read and write EMMC partitions as well as MTD ones.
This enables incremental updates that include boot image changes, as
well as OTA of new recovery partitions.

Change the applypatch function to take meaningful arguments instead of
argc and argv. Move all the parsing of arguments into main.c (for the
standalone binary) and into install.c (for the updater function).
applypatch() takes patches as Value objects, so we can pass in blobs
extracted from the package without ever writing them to temp files.
The patching code is changed to read the patch from memory instead of
a file.
A bunch of compiler warnings (mostly about signed vs unsigned types)
are fixed.
Support for the IMGDIFF1 format is dropped. (We've been generating
IMGDIFF2 packages for some time now.)
