Removed most patches. The last was upstreamed and the others can be worked
around using Makefile.

Removed inactive maintainer.

Added PKG_BUILD_PARALLEL for faster compilation.

Fixed license information.

Massive reorganization of Makefile for consistency between packages.

Removed --with-sql options. These are totally broken when cross compiling.
Leaving them out works just as well.

Added cpp patch as the test needs a header.
