Curb the proliferation of libdraw headers

libdraw provides a lot of ambiguously named headers, which makes it
confusing. This change merges the subdirectories into single headers,
and moves all headers into draw subdirectory, so that it's obvious
at a glance what library the header belongs to.

Compare:

#include <path.h>
#include <source.h>
#include <font/bitmap_backend.h>
#include <font/pcf.h>

vs.

#include <draw/path.h>
#include <draw/source.h>
#include <draw/font.h>
