[PATCH libXfont] readme: Update for libXfont 2.0 interface change

[Adam Jackson]

While xfs can be more or less trivially ported to 2.0, bcftopcf cannot
because the font file I/O API is no longer externally visible. This is
intentional, because bdftopcf is literally the only consumer of that
API, and is itself only used in the build process for the classic core
fonts themselves. The plan for bdftopcf is to import a copy of libXfont
1.5 and link against that statically instead.

+This version of libXfont is not compatible with xfs, or with the legacy
+bdftopcf utility; these packages require libXfont 1.5, not libXfont 2.0
+or later. The two versions can be installed in parallel, and eventually
+the need for 1.5 will go away. We apologize for the inconvenience.
 
 libXfont supports a number of compression and font formats, and the
 configure script takes various options to enable or disable them:
