* [Qemu-devel] [PATCH] Introduce get_datafile_dir() to replace bios_dir

  To: aliguori; +Cc: Amit Shah, qemu-devel

bios_dir really is $(PREFIX)/share/qemu/ (or the dir. specified by
-L). It currently stores some firmware images and keymaps, so the
name bios_dir is really a misnomer.

Replace it with a helper, get_datafile_dir().
