[Freeciv-Dev] (PR#3979) Merge SDL_ttf into FreeCiv tree

["Rafa³ Bursig" <bursig@xxxxxxxxx>]

Hi

        I think we wait enought for Sam Latinga move and it is time to 
make some own actions.
This patch merge SDL_ttf2 lib ( with blended_shaded code ) in freeciv 
tree. We can always remove it when blended_shaded code will go to 
SDL_ttf cvs. Current I only copy SDL_ttf code to gui-sdl and change 
checks in sdl-client.m4 from SDL_ttf to freetype2 lib ( I add 
freetype2.m4 macro ).
I don't change SDL_ttf code in any way (fc coding style and unused 
functions), we can always do it later. Ok... this isn't totaly true 
becouse I fix small bug with use of 2.1.3 (and laters) freetype lib but 
I correct it in sdl-client.m4 and force usage >= 2.1.3 freetype2 lib ( 
current stabel is 2.1.4 ).
