/*
* The search routine takes a directory list, separated by PATHSEP, and
* tries to open a file. Null directory components indicate current
* directory. if the file SUBDIR exists and the file is a font file,
* it checks for the file in a subdirectory named the same as the font name.
* Returns the open file descriptor if ok, else NULL.
