e4a8450909 bootstrap: Added phony rule for bootstrapManifest.
This is for stageMain and prevents build.ninja.in from being
accidentally deleted.

34d3fe9f2b bpdoc: Cache property struct docs by full package path
The full package path is no longer stored in the name variable, pass the
pkg variable into getDocs and putDocs so that types with the same name
in different packages don't collide.

c20adeac4b Support go 1.5
The go compiler and linker changed in v1.5 -- to 'go tool compile' and
'go tool link' instead of 6g and 6l. Move the selection logic to
bootstrap.bash, and have it use compile/link if 6g/6l are missing. This
way the build.ninja.in will continue working with either go 1.4 or 1.5.

Travis and the test suite will fail under 1.5, since the build.ninja.in
is still generated with 1.4, and the function names in the comments
differ between 1.4 and 1.5.

735873d8c5 Fix bootstrap package build stage default
Packages were defaulting to StageBootstrap, while they need to be in
StagePrimary and they'll be moved into StageBootstrap if necessary.

f0ca90124a Support a separate build directory
To provide a consistent __FILE__ behavior with cpp, we want to be able
to run with SRCDIR="." and the outputs be saved elsewhere. Other tools
within android also expect to be run from $TOP.

852191db67 Switch bootstrap.BinDir to a StaticVariable
API Change -- will require changes to any code using bootstrap.BinDir

This way we can put references to other variables in BinDir, and still
be used properly by other packages.

efd2de734d Use three stage builds
This splits the current bootstrap stage into two stages:

A bootstrap stage, which like today, a reference is checked into the
tree. It just builds the "core" blueprint binaries -- minibp,
gotestmain, and choosestage. Just enough to build the next stage's ninja
file.

A primary builder stage. This builds the primary builder, the main ninja
file, and any other bootstrap binaries (bpfmt, etc).

The main advantage here is that the checked in file really only contains
references to blueprint -- not the primary builder. This will allow us
to make the primary builder more dynamic, by loading more module types
that may or may not exist in all trees.

It's even possible to reuse the build.ninja.in in the blueprint repo
directly now. We don't currently do that, since we still want to turn on
tests.

91a657e219 Enhance bootstrap stage selection
This simplifies the bootstrap process while making it more flexible by
moving the stage selection into a go binary(choosestage). It will now be
possible to have more than two build stages.

Now each stage has a ninja template(main.ninja.in) and a timestamp
file(main.ninja.in.timestamp). The timestamp file may be updated by any
build stage that wishes to regenerate the ninja template. If the
choosestage binaries sees that the timestamp is newer than the template,
it will choose the prior stage.

The main stage no longer writes to the source tree to update the
build.ninja.in file. This was a problem for read-only source trees.
Instead, the choosestage binary first checks to see if that file is
newer than the last bootstrap.ninja.in, copies it in place, and starts
the boostrap stage.

The bootstrap stage regenerates it's own ninja template, but that
required a loop through the main stage to actually run it. The
choosestage binary now detects if the template has changed for the
current stage, and will restart the stage.

One change is that if dependencies do get messed up, instead of silently
failing, there's a higher chance that the bootstrap step will just
continue looping, doing nothing. This can happen if the main stage
has a dependency that triggers the bootstrap stage, but the bootstrap
stage doesn't see anything required to rebuild the main ninja file. A
side effect of this requirement is that changes to test code will now
rebuild the main ninja file.

f04c55172f Add test suite for bootstrapping
This only checks to make sure that for a given updated file, the
bootstrap stage is properly run. It doesn't actually check to make sure
that anything was rebuilt.

21b6f37cee Require ninja 1.6.0, remove workaround
The workaround no longer works with the new stage selector. We may run
bootstrap.ninja.in twice before running the next stage, but we can't
encode whether to run another ninja instance in the checked in
build.ninja.in.

This can likely be solved, but now that there's an official release with
support for multiple passes, just push up the required version.

4572edddfa Add self-documenting support
The primary builder will now generate a rule to call itself with
--docs=.bootstrap/docs/<name>.html to produce an automatically
generated documentation file.

The documentation generation process is:
 - Call each factory once to get empty property structs associated
   with the module type
 - Use reflection to determine the names of the type of each property
   struct
 - Use the bootstrap_go_package modules from reading the Blueprints files
   to find the source files for each Go package used to build the primary
   builder
 - Use the go/parser module to find the type declaration for each
   property struct
 - Extract comments for the property struct and each property declaration
 - Format all the comments into HTML

87ba294ceb Add option to build and run tests during bootstrap
Users that want to enable this option can use the '-t' option to
bootstrap.bash when passing '-r'. Builders that want to enable this can
set the RUN_TESTS environment variable in their bootstrap.bash.

The gotestmain tools is needed to write the main functions for the test
binaries, since 'go test' doesn't work well in this environment.

5bdb4ca1a5 Set GOMAXPROCS to number of CPUs
Apparently Go only allows a single thread to be executing by default,
so the increase in performance seen when concurrency was added to
Blueprint was entirely due to scheduling goroutines while the
executing goroutine was blocked in a syscall.  Whoops.

Set GOMAXPROCS to the number of CPUs.  Reduces wall thime by >2x on
one workload.

93ef72d283 Don't fail cleanup when a file has turned into a directory
If .ninja_log contains an entry that used to be a file but is now a
non-empty directory the os.Remove call will fail.  Silently ignore
this error, if the files in the directory are abandoned the directory
will be cleaned up when the files are removed.
