GTP tunnel endpoints (MMEs, GSNs...) will eventually reuse sequence number
values. When handling long capture files this may lead to wrong request/reply
pairs: a message may be considered as a reply to an old request
sharing the same reused seq number
Add an heuristic to the matching algorithm that involves timestamps:
request/reply pair matches only if their timestamps are closer than a
configurable threshold. If such value is 0 (default), timestamps are not
used and only seq number values are evaluated (i.e. fall-back to old behavior)
Note that a wrong match might lead to wrong (gtp-)association/session
While at it, extend messagge list explicitly used by the algorithm

This patch introduces new APIs to allow dissectors to have a preference for
a (TCP) port, but the underlying data is actually part of Decode As functionality.
For now the APIs are intentionally separate from the regular APIs that register a
dissector within a dissector table. It may be possible to eventually combine the
two so that all dissectors that register with a dissector table have an opportunity
to "automatically" have a preference to adjust the "table value" through the
preferences dialog.
The tcp.port dissector table was used as the guinea pig. This will eventually be
expanded to other dissector tables as well (most notably UDP ports). Some
dissectors that "shared" a TCP/UDP port preference were also converted. It also
removed the need for some preference callback functions (mostly when the callback
function was the proto_reg_handoff function) so there is cleanup around that.
Dissectors that has a port preference whose default was 0 were switched to using
the dissector_add_for_decode_as_with_preference API rather than dissector_add_uint_with_preference
Also added comments for TCP ports used that aren't IANA registered.

Have all dissector tables have a "supports Decode As" flag, which
defaults to FALSE, and which is set to TRUE if a register_decode_as()
refers to it.
When adding a dissector to a dissector table with a given key, only add
it for Decode As if the dissector table supports it.
For non-FT_STRING dissector tables, always check for multiple entries
for the same protocol with different dissectors, and report an error if
we found them.
This means there's no need for the creator of a dissector table to
specify whether duplicates of that sort should be allowed - we always do
the check when registering something for "Decode As" (in a non-FT_STRING
dissector table), and just don't bother registering anything for "Decode
As" if the dissector table doesn't support "Decode As", so there's no
check done for those dissector tables.
