bufio.Scanner defaults to a relatively small max line length of
64kB. Kati output may have long lines, use a max length of 2MB
instead.

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.

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.
