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.
define empty request_key method for sumstats in cluster mode.

This prevents the worker nodes from crashing, when request_key is used
in cluster mode and called on the worker and the manager nodes (i.e. when
a non-cluster-aware script is used).

Add a new section "Cluster Configuration" to the docs

Added a new section that is intended as a how-to for configuring a Bro
cluster (this section does not discuss cluster architecture or theory)
that is aimed at beginners to Bro.  Most of this content was moved here
from the BroControl doc (which is now intended as more of a reference guide
for more experienced users) and the load balancing FAQ on the website.

Fix new []/delete mismatch in ~Base64Converter.
Fix buffer overlows in IP address masking logic.

That could occur either in taking a zero-length mask on an IPv6 address
(e.g. [fe80::]/0) or a reverse mask of length 128 on any address (e.g.
via the remask_addr BuiltIn Function).
Fix buffer over-reads in file_analysis::Manager::Terminate()
