staging/android: rename sync_pt_info to sync_fence_info

As struct sync_pt doesn't exist anymore it is a good idea remove any
reference to it in the sync_framework. sync_pts were replaced directly by
fences and here we rename it to sync_fence_info to let the fence namespace
clean.

staging: lowmemorykiller: Make default lowmemorykiller debug message useful

lowmemorykiller debug messages are inscrutable and mostly useful
for debugging the lowmemorykiller, not explaining why a process
was killed.  Make the messages more useful by prefixing them
with "lowmemorykiller: " and explaining in more readable terms
what was killed, who it was killed for, and why it was killed.

The messages now look like:
[   76.997631] lowmemorykiller: Killing 'droid.gallery3d' (2172), adj 1000,
[   76.997635]    to free 27436kB on behalf of 'kswapd0' (29) because
[   76.997638]    cache 122624kB is below limit 122880kB for oom_score_adj 1000
[   76.997641]    Free memory is -53356kB above reserved

A negative number for free memory above reserved means some of the
reserved memory has been used and is being regenerated by kswapd,
which is likely what called the shrinkers.

staging: most: remove unnecessary keep_mbo variable

The MBO pointer stacked_mbo and the boolean variable keep_mbo are
always changed together and therefore provide the same information.
This patch removes keep_mbo and uses stacked_mbo instead.
