Performance profiles

This changes adds support for custom performance profiles through overlays. Supported
devices should define config_perf_profile_prop with the proper system property to be set
and fill an init.rc file with the appropiate handlers for every defined performance profile..

Fix confusing warning dialog behaviour.

The settings app closing when pressing back while the dialog is shown or
clicking outside of the dialog was confusing for the user. Instead, make
sure the user has to acknowledge the dialog.

settings: performance: Update get current values in Processor view

Some users have been complaining about min/max frequency being
set incorrectly on some CM builds.

One way that they could be seeing this is by using the Processor
Performance information in Settings which seems to load the values
for min/max frequency and governor once and then never reloads
them unless you change the actual setting.

This is easy to see by changing the values yourself by modifying
the /sys files directly.

With this commit, changing the /sys files will cause the
Performance view to show the correct values, not the cache values.

Settings: Apply Processor settings to all cpus

QCOMs multicore implementation allows for different governors
and min/max values per cpu. Let the Settings app live up to the
user's assumed expectation and keep values synced across all
available cpus.

While this can be easily accomplished with a root-app, there are
a few prerequisites for our application: This patch requires
ueventd rules for cpu*/cpufreq/scaling_* files and write perms
to cpu*/online for the SYSTEM user in init.${ro.hardware}.rc.

Don't try to restore Set on Boot settings before decrypting

If encryption is enabled, BootReceiver will not be able to find
the performance preferences and set sys.{cpufreq,iosched}.restored
to true, inhibiting the second invocation after decryption from
doing so (because it thinks that the settings were already restored).
This patch fixes that by not attempting to restore settings while
/data is not yet decrypted.
