In this commit, we fix a panic bug that can arise when we attempt to
process a cf checkpoint message from a remote peer. Before this commit,
if the size of the checkpoint cache was large than the number of
checkpoints requested by the peer, we would panic with an out of bounds
error. In order to prevent, this we'll now use the size of the requested
set of hashes as our bound to ensure that we don't panic.
In this commit, we modify the locking scheme when serving cf checkpoints
for peers to allow the server to serve multiple peers at the same time.
Before this commit, we would first grab the write lock, check to see for
expansion, then release the read lock. In this commit we reverse this
and instead will grab the read lock, and upgrade to the write lock if we
need to actually expand the size of the cache.
In this commit, we fix a bug in the way that we previously attempted to
server cfcheckpoints. In the prior version we would never actually
fetch the current length of the cache. As a result, after the first time
the checkpoints were fetched, we would always continually grow the
cache rather than using what's there if sufficient.
In this commit, we fix this behavior by always checking the length, then
either keeping the rite lock, or downgrading to a read lock if the size
was sufficient.

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)
