libfuse: Add '[no_]auto_inval_data' mount option
Several caching logic changes have been made on the kernel side
to better support network-based fuse filesystems. These include
kernel side mtime checking and read path cache revalidation. The
new caching logic is enabled through the FUSE_AUTO_INVAL_DATA
init flag. Export this to the user via the '[no_]auto_inval_data'
mount option.
