This way we only have one way to start a build, which always has logging
/ tracing / etc, even if we don't need Kati.
There's two ways to use this:
As a direct replacement for mkdir out; cd out; ../bootstrap.bash;
./soong -- as long as --skip-make is always passed, we'll never run
Kati, and Soong will run outside of it's "make" mode. This preserves
most of the speed, and allows full user control over the Soong
configuration.
A (experimental, dangerous) way to temporarily bypass the product
variable and kati steps of a build. As long as a user is sure that
nothing has changed from the last build, and they know exactly which
Ninja targets they want to build (which may not be the same as the
arguments normally passed to 'm'), this can lead to shorter build
startup times.

The build now uses a prebuilt javac binary distributed with the
source, checking the host java version is no longer required.

some more manifests to include the prebuilts.

This causes Soong to put the outputs of each genrule into a temporary
location and copy the declared outputs back to the output directory.
This gets the process closer to having an actual sandbox.

This speeds things up a little bit, but the major win is that we don't
need to recursively call into the build during the auto installclean.

This way kati won't need to be run as often (either initially, or when
switching products with the same device).

When kati keeps state around, it has to regenerate the ninja file every
time the state is changed. So move the java version checking into
soong_ui, where we can parallelize it with other operations instead of
only checking it occasionally.

So that we don't have to load up all the makefile state just to remove
the output directory.
Starting from a completely empty out directory:
kati: 16s
soong_ui: 2.0s
From a minimal out directory (m -j blueprint_tools):
kati: 3.8s
soong_ui: 0.4s

Wrap os/exec.Cmd to use our Context and Config interfaces for automatic
logging and error handling. It also simplifies environment modification
based on the Config's environment.
This also adds sandboxing on Macs using sandbox-exec. A simple profile
is provided that only logs on violations, though multiproduct_kati on
AOSP has no violations. This isn't applied to ninja, only make / soong /
kati to start with. I measured <5% time increase in reading all
makefiles, and no noticable difference when kati doesn't regenerate.
I'd like to spin up a process to dump violation logs into our log file,
but the log reporting changed over the range of Mac versions that we
support, so that's going to be more complicated. Opening Console.app
works in all cases if you're local -- just search/filter for sandbox.
Linux sandboxing will be implemented later -- the sandbox definition is
opaque enough to support a different implementation.

Right now this mostly just copies what Make is doing in
build/core/ninja.mk and build/core/soong.mk. The only major feature it
adds is a rotating log file with some verbose logging.
There is one major functional difference -- you cannot override random
Make variables during the Make phase anymore. The environment variable
is set, and if Make uses ?= or the equivalent, it can still use those
variables. We already made this change for Kati, which also loads all of
the same code and actually does the build, so it has been half-removed
for a while.
The only "UI" this implements is what I'll call "Make Emulation" mode --
it's expected that current command lines will continue working, and
we'll explore alternate user interfaces later.
We're still using Make as a wrapper, but all it does is call into this
single Go program, it won't even load the product configuration. Once
this is default, we can start moving individual users over to using this
directly (still in Make emulation mode), skipping the Make wrapper.
Ideas for the future:
* Generating trace files showing time spent in Make/Kati/Soong/Ninja
(also importing ninja traces into the same stream). I had this working
in a previous version of this patch, but removed it to keep the size
down and focus on the current features.
* More intelligent SIGALRM handling, once we fully remove the Make
wrapper (which hides the SIGALRM)
* Reading the experimental binary output stream from Ninja, so that we
can always save the verbose log even if we're not printing it out to
the console
