BUG#27769 - MySQL should include debian packaging dir

Replaced hardcoded sover reference with variable.
Removed references to added manpages.
---
BUG#27769 
Cleaned up some things to make building the packages go a little smoother. 
---
debian/rules really does need to be called from the source root.
---
Fixed two problems with the build caused by adding debian to the source tree
---
Left off the debian/ prefix to the Makefile filter.
---
BUG#27769 - MySQL should include debian packaging dir
Changed substitution variables to match already existing autoconf vars.
Generate debian/control and debian/defs.mk from autoconf now, since we run that
to make a source package. 
---
Corrected incorrect variable name
---
Renamed template files to have shorter names. 
---
Moved generation of debian/control to dist-hook so make clean won't eat it.
---
A few final changes to make debs build from a source tarball dist.
