btrfs: rename extent map functions to get block start, end and check if in tree

These functions are exported and don't have a 'btrfs_' prefix in their
names, which goes against coding style conventions. Rename them to have
such prefix, making it clear they are from btrfs and avoiding potential
collisions in the future with functions defined elsewhere outside btrfs.
