Make PackageVarContext implement PathGlobContext by implementing
GlobWithDeps. This will allow calls to ExistentPathForSource
inside a VariableFunc to use optimized glob dependencies instead of
falling back to AddNinjaFileDeps, which is resulting in extra
dependencies from soong_build on top level directories, triggering
extra Soong regenerations.
Remove the fallback path in ExistentPathForSource by making it take
a PathGlobContext, which is now a superset of PathContext.
Rewrite TestNinjaDeps to not rely on the unoptimized glob dependencies
in VariableFuncs and instead call ctx.Config().AddNinjaFileDeps
directly.

This will make it easy to change a "false" boolean to "true" to push
`--bazel-mode` by default for all users.
Users may disable bazel-by-default with BUILD_BROKEN_DISABLE_BAZEL, and
bazel is disabled by default on Darwin hosts (due to lack of test
coverage).

This helps with incrementality a lot: the symlink forest must depend on
almost every directory in the source tree so that if a new file is added
or removed from *anywhere*, it is regenerated.
Previously, we couldn't do this without invoking bp2build, which is
quite wasteful because bp2build takes way more time than the symlink
forest creation, even though we do the latter in a very suboptimal way
at the moment.
This means that if a source file is added or removed (which does not
affect globs), we don't pay the cost of bp2build anymore.
Also refactored symlink_forest.go on the side. Too much state was being
passed around in arguments.
This change reimplements aosp/2263423 ; the semantics of not touching an
output file is the exact same as order-only inputs and the latter is a
bit fewer lines of code.

It's better not to have state hidden in dotfiles (or rather,
dotdirectories) if we can help.
It's questionable whether the "linux-x86" path segment makes sense since
soong_build only ever runs on one operating system, but I didn't want to
rock the boat now.
Drive-by fixed some quoting fixes in rbc-run. Notably, I didn't wrap
`$@` into double quotes because I don't know whether the lack of double
quotes was intended or not.
Also drive-by fixed the fact that "out/soong" was added twice to the
directory name of bpglob. This turned out not to be a problem because
bpglob doesn't need to be explicitly built: if it's needed, it's
declared as an input of the glob files so it'll be built automatically
(at the cost of the first "null build" not actually being a null build)

This makes soong_ui the only place where soong_build is invoked, thus
greatly simplifying the conceptual model of the build.
It comes with the slight limitation that now soong_docs (and queryview
and the JSON module graph) are not Make targets anymore, but I suppose
that's an acceptable loss.
The only place where someone depended on soong_docs from a Makefile is
removed in a separate change.

It used to be invoked from out/soong/build.ninja, which required two
soong_build invocations one after the other (ne to generate
out/soong/build.ninja, one to generate the queryview workspace). This
was slower and required some shell-quoted-in-ninja-quoted-in-Go .

This includes the JSON graph generator and bp2build.
Before:
GENERATE_BAZEL_FILES=1 m nothing
GENERATE_JSON_MODULE_GRAPH=1 m nothing
Now:
m json-module-graph
m bp2build
They can now also be combined with other targets or each other.
The longer-term goal is to run "m queryview" and "m soong_docs" using
the same infrastructure. There are two alternate approaches:
1. Call soong_build from within the main Ninja invocation. This requires
two sequential soong_build invocations and is thus slower.
2. Do everything requested in the same soong_build invocation. This
would be faster, but one AFAIU can't tell Ninja that multiple possible
actions can build the same output so that doesn't work.
(1) is somewhat more desirable because soong_docs seems to be built
from build/make/core/main.mk ; I assume that that can be worked around
although I haven't checked where the output of "m soong_docs" goes.

Before, we piggybacked on the implementation of regular soong_build and
wrote a fake build.ninja file to satisfy Ninja.
Now, instead, the JSON module graph is a a separate action in the Ninja
output file. This has the pleasant side effect that one can flip back
and forth between generating the JSON file and regular Soong without
loss of incrementality.
Side cleanup: write .d files in a slightly cleaner way.
Test: Presubmits.

This requires some explanation: turns out, Ninja uses the $builddir
variable declared in the top-level Ninja file to figure out where the
command log should go. This resulted in a loss of incrementality between
the manual Ninja invocation in test_null_build_after_docs because they
used different Ninja files and therefore different values of $builddir.
The reason why this was not a problem before is that the output files of
the main Ninja file and the bootstrap one were separate, but with that
changing, this will start to matter.

The following files are forked:
- build-globs.ninja
- The glob list files
- .d files for the glob list files
- The output file (build.ninja or the bp2build marker file)
This makes bp2build and soong_build not overwrite each other's files
they need for proper incrementality.

The source tree will eventually be made ReadOnly, and recipes that write
directly to the source tree will fail. Use a pattern-match approach on
the results of stdout/stderr to provide hints to the user in such a
scenario.
If multiple patterns are found in raw output, print error hint
corresponding to first pattern match. first pattern match is chosen
since the failing function will be at the top of the stack, and hence
will be logged first
Test: Wrote a unit test to assert errorhint is added to output.
Wrote an integration test that writes to a file in the source tree
1. When source_tree is RO, the recipe fails and an error hint is printed
to stdout
2. When source tree is RW, the recipe succeeds and no error hint is
printed

This CL fixes a typo in writeFakeNinjaFile to correctly write
a fake out/soong/build.ninja and its depfile. It also modifies bootstrap
phase to *not* run the main soong build phase (which takes more than a
minute) if GENERATE_BAZEL_FILES=1.
This change has the side effect that `GENERATE_BAZEL_FILES=1 m nothing`
no longer generates the real build.ninja, which is fine because one
shouldn't be using GENERATE_BAZEL_FILES=1 for that anyway (or, use
USE_BAZEL_ANALYSIS=1). This change has no effect on mixed builds.
Time on a change to Soong or any Android.bp files:
Before: bp2build_workspace_marker (~20 seconds) + build.ninja (1 min)
After: bp2build_workspace_marker (~20 seconds)
Time on the second of two consecutive `b build //bionic/...`: 2.070s

Now, if the same file exists in the generated tree and the source tree,
it symlinks in the generated file instead of failing outright.
Drive-by fix: print errors for all conflicts instead of bailing out on
the first one.

It now handles adding .bp files and changing globs.
In order to do this, depfiles are now written separately from RunBlueprint.
This is necessary due to the confluence of a number of seemingly
unrelated factors:
1. The glob filelist dependencies are discovered in globSingleton
2. Singletons need to be registered because otherwise singleton module
types panic
3. Singletons don't work because they require mutators bp2build does not
run
Due to (1), we would need to run the glob singleton. However, due to (2)
and (3), we can't run singletons and have to run Blueprint with
StopBeforeGeneratingBuildActions, which is when the build actions
writing glob files would be generated. So what happens is:
1. When bp2build is run, the glob singleton is disabled
2. At the end of bp2build, the list of glob files is artifically added
to the depfile of the workspace marker file
3. When build.ninja is generated, the Ninja file containing the glob
list file is written by the now-active glob singleton

This is done by setting the INTEGRATED_BP2BUILD environment variable
when invoking the build.
Even though the name of the marker file insinuates that a Bazel
workspace is already created, this is not the case yet.
An issue that remains is that a .d file is not written for the marker
file so it won't be rebuilt if a .bp file changes. Fixing this requires
delicate surgery because writing the .d file is the result of delicate
interplay between Soong and Blueprint.
There are also a number of semi-related fixes:
- The name of soong.environment.{used,available} is now on the command
line of soong_build (soong_docs is still special cased because its
command line in the Ninja file is taken from the os.Args of
soong_build so it's not trivial to remove the --{available,used}_env
from it
- bp2build writes a separate soong.environment.used file
- I had to call SetAllowMissingDependencies() separately when creating
the android.Context for bp2build so that bp2build runs in the
integration tests (it was not obvious how not to do this)
- Fixed a number of integration tests where a command with an expected
exit code of 1 was used as the last one in a test case, thereby
breaking the test suite
