Motion: include AGG freetype (2.4 version) in MapServer

[Howard Butler]

All,

I've come around to thinking that the only way we can limit the  
configuration/building issues we are about to inflict on our users  
with AGG is to include the freetype stuff in MapServer's source.  It  
seems many of the distros are treating the AGG freetype  
inconsistently.  Just building AGG because of its spartan build setup  
is quite a chore.  Hacking makefiles, compile targets, and link lines  
to get what is needed is just too much.

I propose we take the GDAL "thirdparty" approach and put the AGG  
freetype stuff in ./thirdparty/agg and update MapServer's configure/ 
make system to always use that.  We have done something similar in  
the past with GD, right?  If so, this approach would not be  
unprecedented.
