These changes were supposed to be committed in the previous patch
"Better refcounting and locking" but seem to have gotten lost in a
rebase. It fixes a memory leak and some possible race conditions.

All major externally accessible objects (especially FontFamily and
FontCollection) are now reference counted. In addition, there is a
global lock intended to make operations thread-safe.
WIP notice: in this version of the patch, not all external API entry
points are protected by the lock. That should be fixed.

This patch improves script run itemization and also exposes metrics
and bounds for layouts. In addition, there is a fair amount of internal
cleanup, including ref counting, and making the MinikinFont abstraction
strong enough to support both FreeType and Skia implementations. There
is also a sample implementation using Skia, in the sample directory.
As part of its functionality, his patch measures the bounds of the
layout and gives access through Layout::GetBounds(). The corresponding
method is not implemented in the FreeType-only implementation of
MinikinFont, so that will probably have to be fixed.

This commit removes the direct dependency on FreeType and replaces it
with a MinikinFont abstraction, which is designed to support both
FreeType and Skia fonts (and possibly others in the future).
Also adds a "total advance" to the Layout, with an API for retrieving
it.

This is the initial draft of Minikin, a library intended to perform text
layout functions. This version does basic weight selection and font runs
for scripts, and also has a simple renderer for drawing into bitmaps,
but is lacking measurement, line breaking, and a number of other
important features. It also lacks caching and other performance
refinements.
