lib/db, lib/protocol: Compact FileInfo and BlockInfo alignment (#6215)

Browse Source 
* lib/db, lib/protocol: Compact FileInfo and BlockInfo alignment

This fixes the following two lint warnings

    FileInfo: struct of size 160 bytes could be of size 136 bytes
    BlockInfo: struct of size 48 bytes could be of size 40 bytes

by reordering fields in alignment order (64 bit fields, then 32 bit
fields, then 16 bit fields (if any), then small ones). The end result is
a slightly less aesthetically pleasing struct field order, but since
these are the objects we often juggle in bulk and keep large queues of I
think it's worth it.

It's a micro optimization, but a cheap one.
