Unify three font info structures
* src/ftfont.h (struct font_info): New type, unifies similar types
from ftcrfont.c, ftfont.c and xftfont.c
* src/xftfont.c (struct xftfont_info): Remove, replace with struct
font_info. Adjust all uses.
* src/ftcrfont.c (struct ftcrfont_info): Likewise.
* src/ftfont.c (struct ftfont_info): Likewise.
(cherry picked from commit 9e0d69b5a17a0fa3b0dd099a51584a85f3ddb5bf)
