REMOVED DEBIAN FILES: noone bother to update them since 0.9.22, so kill em all

BTW: should go to 13.1

- Update to 0.9.30
+ implements the "SHOULD" clause of RFC 2616 section 8.1.4, which
may reduce bandwidth consumption when clients cancel requests.
+ fixes build errors with various combinations of operating systems,
libc versions, and configure flags.
+ fixes a use-after-free crash when using epoll() in combination with
read errors
0.9.29:
+ epoll can now also be used with SSL connections
+ following recent HTTP/1.1 clarfications, MHD no longer send
a "Content-length" header in CONNECT responses.
+ the "MHD_add_connection" call now consistently sets an "errno"
value to indicate the cause of errors.
Connections added this way are now always processed immediately.
+ fixes a recently-introduced bug which prevented HTTP pipelining
from working properly in some cases and a build error in
conjunction with the "--disable-messages" configure option.
- Enable build of (experimental) SPDY support.
