This is based on ideas done in experiments/jreed-layout, but
I manually did this again.
Moved around directory structures.
A single python subdirectory under src/lib for single "isc" module.
No "cpp" directories.
No pyshared or includes symlink trees.
I tested running the c++ tests and python tests.
I tested running run_bind10.sh from source tree (with nothing installed).
I tested running bind10 from installed (after moving source).
git-svn-id: svn://bind10.isc.org/svn/bind10/trunk@1120 e5f2f494-b856-4b98-b285-d166d9295462
