libneon2X

Hi,

I compiled tla 1.3.5 with an external libneon25 (for Debian).

Sadly, webdav support broke :(
Namely libneon25 does not escape URIs the same way than libneon24.
I'm checking whether this can be somewhat fixed for both versions
(function abs_path in pfs-dav.c)

Since the libneon API is officially not stable, I think these
incompatibilies will happen more often as time passes, so trying to be
compatible with both versions is a waste of efforts.


libneon is kept inside the tla source archive to ease compilation. I
suggest we also update it to libneon26 and later, and have tla work
with it.

Not only will tla keep up with libneon's evolutions and security
fixes, but we'll also be able to legally compile tla with https
support (with GnuTLS instead of OpenSSL - support added in libneon26).


Suggestions? :)
