buld_error protobuf file is created the moment a build action failed.
This is for external system to detect immediately what caused the
build failure while monitoring the build_progress.pb file.
Bug: b/150401146
Test: * m nothing
* Built successfully aosp_arm-eng and checked build_error file
was not created.
* Modified a cpp file to cause a build failed. Ran m and build
failed. Checked immediately during the build that the
build_error file was created.
* m clean; m and during build, checked if build_error was
removed.

For successful builds, a blank build_error proto file is created.
This slows down the data processing part where it reads the build_error
file and there are no errors to be processed.
Bug: 142277430
Test: Did a successful build and checked if the build_error file
was not available. Changed a source file to make the build
failed and checked if the build_error file was available.

Soong UI generates a proto file named build_progress.pb in $(OUT_DIR)
output directory that contains build action numbers (how many are executing,
finished and total) during the course of a build. This is for external
systems that invokes the Platform Build Systems and would like to know
the completion status.
Bug: b/150401146
Test: Wrote a bash script that continuously read the
build_progress.pb file and computed the build completed percentage
while building the aosp_arm-eng target. Compared the percentage between
the Soong output console and the one reported by the bash script.

Soong UI will generate a new proto file in the out directory for
other systems to read the build completion status during a course
of a build. The proto file contains build action counters where
total_actions: represents the total build actions of a build (will
increase and may decrease during a course of the build)
finished_actions: represents the number of executed build actions.
finished_actions never decreases and finished_actions <= total_actions.
current_actions: represents the number of build actions being executed
and current_actions + finished_actions <= total_actions.

Keep a running map of the critical path to each edge as it

Soong_ui produces a build_error raw file to $(OUT_DIR) where
the file contains a list of build action errors. Each build action
error represents an error raised by a command. The build_error file
is populated if there was a build error.
Bug: b/132969697
Test: Ran m for successful build. Introduced a broken build change,
ran m and verified using printproto that build_error was
generated successfully.

The idea is that we'd move the installation and packaging tasks over to
it, using data from Soong & the Kati reading Android.mk files.
This would allow us to make more fundamental changes about how we
package things without having to adjust makefiles throughout the tree.
Possible use cases:
* Moving some information from Soong's Android.mk output to a file read
by the packaging step may allow us to read the Android.mk files less
often, speeding up builds.
* Refactoring our current two-stage ASAN builds to run the Kati build
step twice, writing into different object directories, then have a
single packaging step that reads both outputs. Soong already has the
capability of writing out a single ninja file with all the asan
combinations.
* Running two build steps, one building the system-related modules
using a "generic" device configuration, and one building the vendor
modules using a specific device configuration. This could enforce a
GSI/mainline system vs vendor split in a single build invocation.
* If all installation is through this tool, it will be much easier to
track what should no longer be installed on an incremental build,
reducing the need for installclean.
* Changing PRODUCT_PACKAGES should be a much faster operation, which
means we could keep track of local additions to the images. Then
`mma` would be more persistent, instead of installing something once,
then never updating it again.
Eventually we plan on switching from Kati to something Go-based, but
this is a more incremental approach while we clean up everything else.
Currently, this just moves the dist-for-goal handling over to the
packaging step, so that we don't need to read Android.mk files when
DIST_DIR changes, or we switch between dist vs not.

The extra `defer os.Remove(fifo)` was sometimes racing with the next
instance of ninja, removing the file in between when it was re-created
and used. Since we're always removing the file before creating it, it's
safe to just remove that.
The error message for this failure wasn't all that good either, so move
so use the status Print/Error calls inside the goroutine instead of the
logging ones.
Test: `build/soong/build_test.bash -only-soong` repeatedly

This adds a new status package that merges the running of "actions"
(ninja calls them edges) of multiple tools into one view of the current
state, and gives that to a number of different outputs.
For inputs:
Kati's output parser has been rewritten (and moved) to map onto the
StartAction/FinishAction API. A byproduct of this is that the build
servers should be able to extract errors from Kati better, since they
look like the errors that Ninja used to write.
Ninja is no longer directly connected to the terminal, but its output is
read via the protobuf frontend API, so it's just another tool whose
output becomes merged together.
multiproduct_kati loses its custom status routines, and uses the common
one instead.
For outputs:
The primary output is the ui/terminal.Status type, which along with
ui/terminal.Writer now controls everything about the terminal output.
Today, this doesn't really change any behaviors, but having all terminal
output going through here allows a more complicated (multi-line / full
window) status display in the future.
The tracer acts as an output of the status package, tracing all the
action start / finish events. This replaces reading the .ninja_log file,
so it now properly handles multiple output files from a single action.
A new rotated log file (out/error.log, or out/dist/logs/error.log) just
contains a description of all of the errors that happened during the
current build.
Another new compressed and rotated log file (out/verbose.log.gz, or
out/dist/logs/verbose.log.gz) contains the full verbose (showcommands)
log of every execution run by the build. Since this is now written on
every build, the showcommands argument is now ignored -- if you want to
get the commands run, look at the log file after the build.
