function.

Only update UI at 1 Hz during nandroid backup/restore

On high-resolution devices such as the Galaxy Note, UI updates
consume more CPU than all other operations.  For example, a nandroid
restore on Note pegs an entire core at 1.4 GHz for the recovery
process while tar is using only 14% of the other core, and iowait
times are low indicating the CPU is not simply waiting for IO.

Nandroid backup/restore should be I/O bound, not CPU bound.

This changes the update interval to 1 Hz during nandroid
backup and restore.

recovery: Allow key to repeat on hold.

This implements the ability to hold a key and have it repeat.
This makes it possible to hold down the volume key to scroll
down to a file.

Enabling repeatable keys:

ro.cwm.enable_key_repeat=true

To control which keys can repeat, you can set this prop with
a list of key codes, like this:

ro.cwm.repeatable_keys=137,200,151,300

If you don't set ro.cwm.repeatable_keys only UP, DOWN, VOL UP
and VOL DOWN will be repeatable.

This is a good commit, but was breaking logging. The proper place to do ui refresh limitation
is in ui_print itself.

Revert "Only update UI at 1 Hz during nandroid backup/restore"

This reverts commit 04076f0722381ca68420c3b9172dac78d3b91017.
Rewrite the code that throttles UI updates to be in ui_print itself.
