Since we don't support using the component build to produce mojo apps,
we can simplify the build targets in a few ways:
*) every mojo_native_application must depend on the c system thunks,
so just make that part of the template instead of requiring the dep
*) there's no such thing as depending on gles2 headers from a component,
so delete the forwarding group.
Most targets that want to use the gles2 headers in a mojo context
want to depend on an implementation through the thunks, so
//mojo/public/c/gles2 does just that. A smaller number of targets (such
as the implementation of the thunks) want to just depend on the headers
but not an impl, so they can depend on //mojo/public/c/gles2:headers.
The //mojo/public/gles target isn't that useful since the only thing we
expose is a set of C entry points.
We can probably also simplify the c system targets, but that's trickier
due to more extensive use from the chromium side.

This adds a tracing service that can aggregate tracing data from
multiple sources and write a json file out to disk that trace-viewer can
understand. This also teaches the shell, sky_viewer, and various other
services how to register themselves with the tracing service and provide
tracing data on demand. Finally, this teaches the skydb prompt to tell
the tracing service to start/stop tracing when the 'trace' command is
issued.
The tracing service exposes two APIs, a collector interface and a
coordinator interface. The collector interface allows different entities
to register themselves as being capable of producing tracing data. The
coordinator interface allows asking the service to collect data from
all registered sources and flushing the collected data to disk.
The service keeps track of all open connections to registered sources
and broadcasts a request for data whenever the coordinator's Start
method is called, then aggregates all data send back into a single
trace file. In this patch, the tracing service simply gives all sources
1 second to return data then flushes to disk. Ideally it would keep
track of how many requests it sent out and give each source a certain
amount of time to respond but this is simple and works for most cases.
The tracing service can talk to any source that is capable of producing
data that the trace-viewer can handle, which is a broad set, but in
practice many programs will want to use //base/debug's tracing to
produce trace data. This adds code at //mojo/common:tracing_impl that
registers a collector hooked up to //base/debug's tracing system. This
can be dropped in to the mojo::ApplicationDelegate::Initialize()
implementation for most services and applications to easily enable
base tracing. Programs that don't use //base, or that want to register
additional data sources that can talk to trace viewer (perhaps providing
data that's more easily available from another thread, say) may want
to create additional connections to the tracing service.

This moves the tracing code and mojoms from sky/viewer/services/ to
mojo/common/ in anticipation of refactoring these to be more widely
usable. This doesn't actually change behaviors yet.

This teaches the SkyDebugger prompt how to tell
the sky debugger (server) to shut down instead of
just calling exit(0).
This also teaches the WindowManagerApp (server) how
to tear down all of its connections itself instead
of depending on the pipes to do so (which would
crash when youd delete the WindowManagerApp as the
pipes could outlive it with WindowManagerImpl objects
containing raw pointers back to the WindowManagerApp).
Shutdown is not yet clean. It errors out trying to
talk to the X11 server, but it's closer to clean
than it was prior to this change. I may add back
and exit(0) to side-step shutdown until it can be
made fully clean.

I had to also register for the text/plain mime-type
which turned out to be harder than expected.
Mostly due to my confusion with mojo_shell
using last-argument-wins argument parsing.
