Raise the FUSE API minor version to 34 and add all
MUSE specific operations and data structures.

MUSE_INIT: Initialize a new connection and installs the MTD
MUSE_ERASE: Erases a block
MUSE_READ: Reads a page with or without OOB
MUSE_WRITE: Writes a page with or without OOB
MUSE_MARKBAD: Marks a block as bad
MUSE_ISBAD: Checks whether a block is bad
MUSE_SYNC: Flushes all cached data
