SBFrame::GetRegisters() (and the .registers / .regs extensions in
Python) returns an array of register-set's, not registers like you might
expect from the API name. Document this.

Instead of maintaining separate swig interface files, we can use the API
headers directly. They implement the exact same C++ APIs and we can
conditionally include the python extensions as needed. To remove the
swig extensions from the API headers when building the LLDB
framework, we can use the unifdef tool when it is available. Otherwise
we just copy them as-is.
