Throw new event for heartbeat messages.

Not tested.
add is_orig to heartbeat event
default to TLS when not being able to determine version
detect and alert on simple case of heartbleed
polish script and probably detect encrypted attacks too.
fix tabs.
make tls heartbeat messages a bit better.
add to local.bro, add disclaimer
also extract payload data in ssl_heartbeat
enable detection of encrypted heartbleeds.
Fix reassembly of data w/ sizes beyond 32-bit capacities (BIT-348).

The main change is that reassembly code (e.g. for TCP) now uses
int64/uint64 (signedness is situational) data types in place of int
types in order to support delivering data to analyzers that pass 2GB
thresholds.  There's also changes in logic that accompany the change in
data types, e.g. to fix TCP sequence space arithmetic inconsistencies.

Another significant change is in the Analyzer API: the *Packet and
*Undelivered methods now use a uint64 in place of an int for the
relative sequence space offset parameter.

Update SNMP analyzer's DeliverPacket method signature.
