The CAmount name is not helpful as its just an int64_t and not a
class, like the name implies. There were a handful of places where
it was passed in as const-ref, as a good example of this actually
creating sub-par code.
The 'server' library has always been a catch-all and
ideally only the hub links it in (far future goal).
In line with this I move a list of files out of server
into the utils lib.
I choose 'utils' because all these are plain old data
objects that many crypto apps will find useful.
now in utils/primitives/

hash.h is now in utils/
The new UnspentOutputDatabase classes are only very loosly a database, we
purely register and store unspent outputs there. But unline a DB we don't
allow modification (just insert and delete).
This replaces the coin-db (which was based on leveldb) and as first goal
this gives us a higher level of stability. The level-database was known
to give corruption issues.
Notice that users will need to do a manual reindex on first update.
