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.

In order to support multi-stage recovery packages, we add the
set_stage() and get_stage() functions, which store a short string
somewhere it can be accessed across invocations of recovery. We also
add reboot_now() which updater can invoke to immediately reboot the
device, without doing normal recovery cleanup. (It can also choose
whether to boot off the boot or recovery partition.)
If the stage string is of the form "#/#", recovery's UI will be
augmented with a simple indicator of what stage you're in, so it
doesn't look like a reboot loop.

Recovery's init.rc was missing a line (added to the main system's
init.rc in change Ic97fd464440ff4a29fc9da7ad15949ac5215ade3) is
required for secure adb to work.

Introduce two new updater functions:
* set_metadata
* set_metadata_recursive
Long term, these functions are intended to be more flexible replacements
for the following methods:
* set_perm
* set_perm_recursive
Usage:
set_metadata("filename", "key1", "value1", "key2", "value2", ...)
set_metadata_recursive("dirname", "key1", "value1", "key2", "value2", ...)
Description:
set_metadata() and set_metadata_recursive() set the attributes on a file/directory
according to the key/value pairs provided. Today, the following keys are
supported:
* uid
* gid
* mode (set_perm_extd only)
* fmode (set_perm_extd_recursive only)
* dmode (set_perm_extd_recursive only)
* selabel
* capabilities
Unknown keys are logged as warnings, but are not fatal errors.
Examples:
* set_metadata("/system/bin/netcfg", "selabel", "u:object_r:system_file:s0");
This sets the SELinux label of /system/bin/netcfg to u:object_r:system_file:s0.
No other changes occur.
* set_metadata("/system/bin/netcfg", "uid", 0, "gid", 3003, "mode", 02750, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0);
This sets /system/bin/netcfg to uid=0, gid=3003, mode=02750,
selinux label=u:object_r:system_file:s0, and clears the capabilities
associated with the file.
* set_metadata_recursive("/system", "uid", 0, "gid", 0, "fmode", 0644, "dmode", 0755, "selabel", "u:object_r:system_file:s0", "capabilities", 0x0);
All files and directories under /system are set to uid=0, gid=0,
and selinux label=u:object_r:system_file:s0. Directories are set to
mode=0755. Files are set to mode=0644 and all capabilities are cleared.

Change I84c0513acb549720cb0e8c9fcbda0050f5c396f5 moved reboot
functionality into init but did not update the recovery partition; so
"adb reboot" and /system/bin/reboot in recovery are both broken.

When installing a package, we should have /tmp and /cache mounted and
nothing else. Ensure this is true by explicitly mounting them and
unmounting everything else as the first step of every install.
Also fix an error in the progress bar that crops up when you do
multiple package installs in one instance of recovery.

Recovery changes:
- add a method to the UI class that is called when a key is held down
long enough to be a "long press" (but before it is released).
Device-specific subclasses can override this to indicate a long
press.
- do color selection for ScreenRecoveryUI's menu-and-log drawing
function. Subclasses can override this to customize the colors they
use for various elements.
- Include the value of ro.build.display.id in the menu headers, so you
can see on the screen what version of recovery you are running.

Modify the OTA installer to understand SELinux filesystem labels.
We do this by introducing new set_perm2 / set_perm2_recursive
calls, which understand SELinux filesystem labels. These filesystem
labels are applied at the same time that we apply the
UID / GID / permission changes.
For compatibility, we preserve the behavior of the existing
set_perm / set_perm_recursive calls.
If the destination kernel doesn't support security labels, don't
fail. SELinux isn't enabled on all kernels.

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.

When doing a cache wipe or a factory reset (which includes a cache
wipe), save any last* log files in the /cache/recovery directory and
write them back after reformatting the partition, so that wiping data
doesn't lose useful log information.

Recovery currently has a random mix of messages printed to stdout and
messages printed to stderr, which can make logs hard to read. Move
everything to stdout.
