7f97c7ea9a build: Don't generate symlinks in include/ dir 
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/

e890c37704 [bcache] Some work on bcache_invalidate() 
bcache_invalidate() now returns a bool to indicate success.  If fails
if the block is currently held, or the block is dirty and writeback
fails.

Added a bunch of unit tests for the invalidate functions.

Fixed some bugs to do with invalidating errored blocks.
