This duplicates building common blueprint go packages between minibp and
the primary builder, but drastically simplifies the first stage,
removing the need to check in a generated build.ninja.in.

From commit 38cef8ac3979da8e13037540981fe7aecc1e1fbe
Removes Go 1.7 from travis, since this depends on os.Executable
Change-Id: I58e2ae542621ffad66e9e145031091cb93ebb497
If tests have a TestMain method the os import is unused and
breaks building the test.
Test: gotestmain/testmain_test.go

Use testing.MainStart to support test packages that implement
TestMain for initial setup and teardown.

Patterns that were not wild would return an empty "dirs" list if the
file was found. But then if they were removed, we wouldn't know to
update the glob file and re-run the primary builder.
In this case, instead of adding the final directory into the dirs list,
add the matched files themselves. Due to editors performing atomic
writes (the directory timestamp often gets updated at the same time as
file timestamp) this is probably more efficient. In either case, we're
only re-running the individual glob, which is rather cheap.
Rename startGlob/Glob return name from "dirs" to "deps" since it may
contain files now too.
Darwin has a default limit of 256 open files per process. Parsing
too many blueprint files in parallel can hit the limit. Cap the
concurrency at 200.
Test: manual testing with limit set to 32

Spaces normally don't need to be escaped, but leading spaces are
trimmed. Escape leading space to allow setting a variable to a
value with leading spaces.

This still isn't the best experience for users, but it at least provides
enough information for someone more familiar with the build to
understand the problem.
It is not allowed to directly use BaseDependencyTag as customized
user dependency tag passed down to BP since it might cause issues
that different type of modules will be mixed when fetched based on
Tag.
In order to use certain syscalls, some source must only be compiled on
one of darwin or linux. There are also cases where it's simplest to have
two implementations of a method (or struct) instead of choosing an
implementation at runtime.
The standard go tools use _<GOOS>.go for this, but the explicit structs
map better into the current blueprint format (and you can still use
_darwin.go / _linux.go to maintain compatiblity with those tools).
Test: Define _linux.go / _darwin.go files, ensure only one is compiled.

Add globbing to filesystem mocking so that more code can be tested
against the mock. Also moves the filesystem mock to pathtools,
and renames pathtools.GlobWithExcludes to pathtools.Glob, replacing
the existing pathtools.Glob.
Test: blueprint tests

f.Scope.Objects is a map, so iteration order isn't defined. To fix this,
lets just sort the testcase list so that it's always consistent.
There are still some paths in the built go files, but this improves
repeatability using the same paths.
Test: Build twice, compare generated test.go files.

If GOROOT is a relative path (like it is in Android), then changing
directories to run the test will cause GOROOT to become invalid. So make
it absolute if we're going to change to a different directory.
This allows tests to use the go tools without searching for a valid go
installation.

matchString was implemented separately on older go versions since they
didn't want a build dependency on the regex package from the testing
package.
Starting in Go 1.8, this is implemented using a internal package to
break the dependency, but until we require that everywhere, just copy
the regex implementation like the old `go test` did. I'm not sure we'll
be able to use the internal package in the future anyways.

We haven't been building the tests for any Go tools that get built
during the primary stage, since we haven't been passing -t to the
primary builder. So enable them there so that we test those tools.

The tests/test_tree/blueprint symlink causes find to print a warning
in the Android build:
find: File system loop detected; `./build/blueprint/tests/test_tree/blueprint' is part of the same file system loop as `./build/blueprint'.
Make the symlink when running the test instead.

Hidden files are often source control related (".git", ".repo", etc) or
editor related (vim's .*.swp), so are not guaranteed to exist, and may
be temporary. The build system shouldn't be using these files by
default.
If the glob pattern explicitly uses "." at the beginning of a path
component, allow returning hidden files for that component. Because of
this behavior, non-wildcard globs remain unchanged.
The one behavior that cannot be handled anymore is including hidden
files in recursive globs.

Instead of forcing every mutator or module to use VisitDirectDeps
to iterate through its deps, allow it to request a dependency by
name to return the Module.

Mutator context goroutines appending directly to the global Context's
replacements list causes a data race. Send them over a channel
instead.
The renames and replacements are local to the mutator, so move them
out of Context and into the runMutator method.
