Define and use read_u{8,16,64}

A large portion of the utility functions is parsing the data structures
on disk. The pattern always involve: reading a certain size of data,
ensuring that there is enough space available; converting the value from
big-endian to host byte order and advancing the pointer pass that value.
Define new functions to capture this task. Use these functions for
parsing the TrillanLogRoot descriptor.
