Fix systrace logging, total paused time, and bytes saved message.
Moved the GC top level systrace logging to be inside of Collector::Run.
This prevents cases where we forgot to call it such as background
compaction. Fixed a unit error regarding total pause time. Fixed
negative bytes saved to use the word "expanded".

Fix dumpsys meminfo <pid>.
Added a case for BumpPointerSpaces. Confirmed working non-debug.
Should also work in debug builds.

Add histogram for GC pause times.
Printed when you dump the GC performance info.

Improve histogram and timing logger dumping.
We now dump the sum (total time) of each histogram as well as
previous stats. This is useful for the GC since the same split can
occur multiple times per GC iteration. Also did a few memory
optimizations by changing the map in the cumulative loggers
to be a set.

Fix up TODO: c++0x, update cpplint.
Needed to update cpplint to handle const auto.
Fixed a few cpplint errors that were being missed before.
Replaced most of the TODO c++0x with ranged based loops. Loops which
do not have a descriptive container name have a concrete type instead
of auto.

Fix histogram memory issues.
Before we had buckets of 5 micro second size. For a 100 MS GC
this used at least 16 * (100 / .005) bytes of storage inside of the
histogram data structure. If you consider the 3 different GC types,
and each timing logger having its own histogram its easy to see
how memory used was significant.
We now have an upper bound on the number of buckets (default 100).
When we hit the upper bound we simply combine adjacent buckets
together. This reduces the total number of buckets by a factor of
2, while increasing the bucket size by a factor of 2. This means
that we may lose a slight amount of precision, but the confidence
intervals remain nearly as useful.
Total unknown memory (occam-svelte):
Before: 45648 kB:
After: 33304 kB
There are probably still some additional optimizations which can be
done as disabling histograms altogether reduces the memory used by
another ~2mB.
A bit of other cleanup in image_space.cc and dlmalloc_space.cc.

Create separate Android.mk for main build targets
The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
