3425d33506 blockchain/indexers: Add methods on CfIndex for batch retrieval. 
Fetching all items in one db transaction will save time when
responding to getcfilters or getcfheaders requests.

d07fd2f333 blockchain/indexers: Reduce duplication in cfindex. 
The index will hold three types of entries for each filter type, block
pair: filter, header, and hash. Since they all have similar methods
and implementations, refactor to reduce duplication.

f4060b107c blockchain/indexers: check for ErrNoData in extended filters 
Since the tx hash has moved to the basic filter, generating an extended filter
can result in `ErrNoData`. This is handled by writing a nil filter and giving
it a zero hash.

621c73dad1 multi: change cfilter Extended bool to FilterType uint8 
The cfilter BIP specifies that the filter type is a uint8. The
current code encodes it correctly on the wire, but everywhere else,
it's treated as a boolean (false for basic filter, true for
extended). This commit corrects that to account for possible
additional filter types in the future. All package changes are
done in one commit as they're all interdependent. The following
packages are updated:

* blockchain/indexers
* btcjson
* peer
* wire
* main (server.go and rpcserver.go)
