e9b8cfb632 atrace: add support for tracing kernel functions
This change adds support for tracing specific kernel function calls using the
function_graph tracer.  It adds a '-k' option to atrace that accepts a comma
separated list of kernel function names for which tracing will be enabled.

6eea6fb259 atrace: clean up tracing option enabling
This change switches atrace to use a table-driven approach to enabling and
disabling options.  It unifies how framework and kernel tracing are enabled,
and causes userland tracing options to be picked up by currently running
processes.

e8744fd4dc atrace: make clock & bus bw tracing optional
This change makes enabling clock tracing and bus bandwidth tracing depend on
whether the device's kernel supports these features.  If it's not supported it
will be skipped.

4b23eefd72 atrace: enable running on user builds
This change allows atrace to be run on a user build, where it is not run as
root.  Some command line options still require root, and atrace will refuse to
run if those options are specified when run as non-root.

This change adds the -z command line flag to atrace to enable support for
compressing the trace with zlib as it's printed to stdout.

interactive governor tracing enabled in the kernel.
