Add Truetype and Type 1 font embedding support

Sorry this is such a large CL.  It was very exploratory for me to make this
work.

- Add an interface to SkFontHost to retrieve font information and provide NULL implementations on all platforms except Linux.
- Segment large Type 1 fonts into fonts with shared resources with 255 glyphs each.
- Convert the various Type 1 formats to the form PDF wants.
- Update font as we draw text instead of as part of the graphical state.
- Remove built-in font support, we can't really use it.

Other changes I can pull out to a separate CL if you like.

- Add SkTScopedPtr class.
- Fix double free of resources.
- Fix bug in resource unique-ifying code.
- Don't print anything for any empty clip path.
- Fix copy paste error - MiterLimit.
- Fix sign extension bug in SkPDFString
- Fix FlateTest rename that was missed on a previous commit.
