Edward Z. Yang f3d050c517 Fix two bugs with caching of customized raw definitions.
The first bug is that we will repeatedly write out the result
of a customized raw definition to the filesystem, even when a cache
entry already exists.

The second bug is that caching these definitions doesn't actually
work (the cache entry is written but never used.)  A new API
for retrieving raw definitions permits the user to take advantage
of caching.
