This only barely works. We pull down system libraries
once before we attach. The libraries we pull from
the device do not have debug symbols, but have enough
that we have decent callstacks. We launch a background
process to repeatedly update a cache directory with
symlinks into our build directory corresponding to the cache
names used on the device, however gdb doesn't watch
the solib-search-path directories to notice the links
as we add them.
Better solutions would be to add support for pulling
down full android symboled system images and using those
instead of pulling libraries off the device as well as
figure out how to get android binaries to support
build-id so that we can present a directory of build-id
associated libraries to gdb on boot and have it to build-id
based lookups of libraries instead of our current broken
watch-logs-and-add-symlinks approach.
If you know what you're doing with this you can actually
make debugging work on the device. It's not particularly
user friendly yet, but we'll work on it.
I added a build_dir member to skypy.paths.Paths
as a temporary measure before we move off of skypy's
paths and onto mopy's paths. This helped eliminate
problems with using a relative path in args.build_dir
as is common.

This mostly works. I haven't yet set up pulling down the
system binaries from the device to the host so that symbols
appear correctly, but I'll do that in the next patch.
One of the crazy things this patch adds it a script
to watch for loads on adb logcat and set up mappings
from the cache library names to the symboled binaries
in the out directory. Presumably other scripts may
want to share this functionality so I've made it its
own script.
Better would be to have mojo_shell spit out a file
including the cache mapping information and we could
watch that file instead of logcat, but this works
for now.

Previously, the trace coordinator would try to write a trace to the file
system, but it is awkward to write to the file system on Android. Instead, we
now stream the trace data to a data pipe. The Sky debugger consumes that data
pipe and sends it to the host via the command HTTP server.

Add a simple example based on the window and view managers.
The skydb app can now handle apps that want to embed another view.
Corrected a problem in unique module name generation. An otherwise unique module name could be shadowed by a parameter name (service_provider in ViewManagerService Embed). Appended a "$" suffix to module names to avoid the collision.

This fixes 3 little bugs in skydb:
1. Adds a logcat command to make it easy to see android logs
2. Fixes using relative build dirs in skydb start
3. Stops sending /quit to debugger.cc since mojo shutdown
doesn't actually work (crashes).
--gdb is still broken, but I'll fix that in a second change.

I changed skydb start to take a build directory
and read the configuration out of gn args instead
of --release, --debug, etc. This should be more
flexable and handle all the crazy asan cases
mopy/config.py tries to. Once we merge sky/tools
into mojo/tools we should make mopy/config use this
method too.
This follows similar patterns to what
mojo/tools/android_mojo_shell.py does, but doesn't
use as much of the (old) android_commands and forwarder
logic. We could even remove all of that
build/android/pylib code by calling the (new)
adb reverse instead of using Forwarder (in a later patch).
This still only supports a single skydb running
at once, but it should be trivial to move the
skydb.pids file into the build directory or to have
it support more than one instance. The big question
there is what the command-line usage should look like
when supporting more than one running instance. See
the mojo-dev thread on the subject.

This makes skydb pass a command_port to prompt.cc
as a commandline argument. I removed passing of the
url and instead pass the url via a separate /load command.
This has the nice side effect of guarenteeing that
the sky instance is up and ready to respond to commands
when skydb exits. It also prepares us for running
more than one copy of prompt.cc as jamesr requested
for both Release and Debug or for on both your android
device as well as your local machine.

This makes it much easier to work with a device where we
don't expect a persistent commandline session. Prompt no longer
actually makes a prompt but rather just runs an http server.
This is just a v1 patch. It doesn't work with android yet
and it isn't smart enough to allow you to run more than one
copy of prompt.cc at the same time (since you can't control
the port it listens on). If you have a second copy of
prompt runnning (or anything else bound to port 7777) it will
just crash.
We could make this a lot better, including splitting out the
pid-file tracking for sky_server into sky_server instead of
having skydb manage it.

This is a proof of concept for replacing ui/views
code with Sky instead. erg says this will allow him
to delete 10s of thousands of LOC from mojo.
Mojo does not yet expose the current binary's URL:
https://docs.google.com/a/chromium.org/document/d/1AQ2y6ekzvbdaMF5WrUQmneyXJnke-MnYYL4Gz1AKDos
So I've worked around that by passing the url
of the binary via the helper script.
I discovered several bugs in the wm_flow code
including that it doesn't handle view resizes
(during embiggen). Related, I discovered that
every time a new window is made it drops the
connections to the embedded.cc app from the
previous window, since the ViewManagerDelegate
is incorrectly implemented as part of the
ApplicationDelegate on both app.cc and embedded.cc.
We'd need to split out a separate per-view object
in both of those apps to handle the
ViewManagerDelegate calls.
There are some changes to logging during loading
as well as the CopyToFile helper to have better
error reporting. I hit several issues early on trying
to get mojo to load the http: urls correctly, including
eventually running out of disk space on my /tmp
and mojo then silently failing to launch the app
(due to mojo never clearing its caches crbug.com/446302).
I had to re-write the mojo_demo.sh script in python
as well as split the sky_server handling code out of
skydb into a separate python module in order to cleanly
launch sky_server. We could use a separate server
if we wanted to but the primary benefit of sky_server
is that it sets up the proper url->disk mappings into
the generated file directories, etc.

-Add a --testing flag to sky_viewer and cause it to paint into an
SkBitmap instead of a ganesh surface so we can get the pixels out.
-Add GetPixelsForTesting to layer.cc to actually grab out the pixels.
-Add a reftest and a mismatch reftest. They need a setTimeout after
the load event. Unclear why or what the right fix is. Maybe we should
give internals some way to force the paint? If we don't have the
setTimeout, we paint a white page (so we do a paint, but with no
content).
-Add a DisplayDelegate to Layer so that Viewer can decide whether
to use the real ganesh backend or the SkBitmap one without littering

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.
