Renamed lfs_entry_t -> lfs_mattr_t

Browse Source 
Attributes are used to describe more than just entries, so calling these
list of attributes "entries" was inaccurate. However, the name
"attributes" would conflict with "user attributes", user-facing
attributes with a very similar purpose. "user attributes" must be kept
distinct due to differences in binary layout (internal attributes can
use a more compact tag+buffer representation, but expecting users to
jump through hoops to get their data to look like that isn't very
user-friendly).

Decided to go with "mattr" as shorthand for "meta-attributes", similar
to "metadata".
