Test: mkdir errtest \
&& ln -s /tmp/dontexist errtest/Android.bp \
# and add errtest to ./Android.bp \
&& m nothing \
# and check that the error message mentions a symlink

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.
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.

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.

Bypassing c.glob() and using filepath.Glob() directly for non-glob
paths does not add dependencies on directories that contain missing
files. For optional_subdirs, this means no dependency is added to
rerun the primary builder when an Android.bp file is added to an
optional_subdirs directory. Always use c.glob(), for the non-optional
case it will not insert any dependencies if the file exists (as tested
by glob_test.go's no-wild tests), and if the file doesn't exist the
len(matches) == 0 will error out.

Sometimes os.Stat on a path seems to return nil after filepath.Glob
returned the path as valid. Return the error message to see why.

Add globbing with dependency checking to blueprint. Calling
ModuleContext.GlobWithDeps or SingletonContext.GlobWithDeps will return
a list of files that match the globs, while also adding efficient
dependencies to rerun the primary builder if a file that matches the
glob is added or removed.
Also use the globbing support for optional_subdirs=, subdirs= and build=
lines in blueprints files. The globbing slightly changes the behavior
of subname= lines, it no longer falls back to looking for a file called
"Blueprints". Blueprint files that need to include a subdirectory with
a different name can use build= instead of subdir= to directly include
them. The Blueprints file is updated to reset subname="Blueprints" in
case we want to include subdirectories inside blueprint and the primary
builder has changed the subname.
Also adds a new test directory that contains a simple primary builder
tree to test regeneration for globbing, and runs the tests in travis.

If the initial non-wild part of a glob path does not exist, return
the last existing part of the path as a dependency to detect if the
path is created later.

Add GlobWithExcludes, which takes a pattern and a list of exclude
patterns, and returns all files that match the pattern but do not
match any exclude patterns.

Recursive globs are supported by passing ** in any single non-final
path element. For example, path/**/*.java will find all files named
*.java under "path".

The directory structure:
a/
a
b/
b
With the glob pattern */a would previously return []string{"a"} for
dirs, but it needs to return []string{"a", "b"} in order to re-run
the generator if a file called "a" is created inside b/.
Rewrite Glob to manually recurse through path elements, only calling
filepath.Glob for a pattern with wilds in the last element of the
path, and add the globbed directory to the dirs list each time.
Also add tests and test data for pathtools.Glob.

regexp is overkill for a simple extension replacement, just find
the last '.' and add the new extension after it. Saves 5% cpu time
on one workload.

Make integrating with go tools easier by putting the blueprint package
files in the top level directory of the git project instead of in a
subdirectory called blueprint.
