Lubomir Rintel 972e0d2803 all: rename the introspection data to use the interface paths in names
This makes it easier to install the files with proper names.
Also, it makes the makefile rules slightly simpler.

Lastly, the documentation is now generated into docs/api, which makes it
possible to get rid of the awkward relative file names in docbook.
