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.
