cleanup:
- don't use enum in struct / return values
- don't use a getter for preferences but a global pointer
- explicitely make enums start at 0
- use static tables for header/footer settings
- remove unneeded memset before strlcpy
- use static buffer allocation, not dynamic
- check header/footer preferences before using the callbacks
- don't include font filename in archos player preferences (break
file format)
bugfix:
- statically allocate old preferences in tv_set_preferences()
Sometimes I can read a file on Clipv2, but it still aborts quite often
