Instead of calling gcry_cipher_open() and gcry_cipher_close() in
a loop, call gcry_cipher_reset to avoid
creating and releasing contexts.
Besides the performance improvement,
this should also fix Coverity 1450453,
which detects the multiple calls to gcry_cipher_close()
as a double-free.

Removed all guards for HAVE_LIBGCRYPT, change autotools and CMake to
error out if it is not available. Update release notes, developer
documentation and README with the new status. Clarify relation with
GnuTLS in macosx-setup.sh. Install Libgcrypt via brew script.
Motivation for this change is that many dissectors depend on Libgcrypt
and having it optional increases the maintenance burden (there have been
several compile issues in the past due to the optional status).
Furthermore, wsutil has crypto code that can be replaced by Libgcrypt.

They already know who they are when they register themselves. Saving the
handle then to avoid finding it later.
Not sure if this will increase unnecessary register_dissector functions
(instead of using create_dissector_handle in proto_reg_handoff function)
when other dissectors copy/paste, but it should make startup time
a few microseconds better.

This saves many dissectors the need to find the data dissector and store a handle to it.
There were also some that were finding it, but not using it.
For others this was the only reason for their handoff function, so it could be eliminated.

The preferences are still supported for backwards compatibility, but the heuristic_protos file has final say on the "preference" to enable/disable a heuristic dissector.
Also add parameter to heur_dissector_add() for the "default" enable/disable of a heuristic dissector. With this parameter, a few more (presumably weak) heuristic dissectors have been "registered" but of course default to being disabled.

Specifically:
- Set packet.h to be the first wireshark #include after
config.h and "system" #includes.
packet.h added as an #include in some cases when missing.
- Remove some #includes included (directly/indirectly) in
packet.h. E.g., glib.h.
(Done only for those files including packet.h).
- As needed, move "system" #includes to be after config.h and
before wireshark #includes.
- Rework various #include file specifications for consistency.
- Misc.

Hopefully that name makes it clear what the routiner's purpose is, and
will encourage people to use it rather than using dissector_add_uint()

set of fields (e.g., a "command") seems wrong or if an exception
occurs fetching data before previous fields have been displayed.
In general: just fetch/dissect from start to end: If there is missing
data, a Wireshark exception will eventually occur;
Add lwm subtrees under the lwm protocol tree (*not* as protocols
under the top (outermost) tree.
Fix a bug which caused an exception to be reported as:
"[Packet size limited during capture: LwMesh truncated]"
rather than as the correct: "[Malformed...]"
col_...() and expert...() functions shouldn't be called under 'if(tree)';
Register the heuristic dissector using "IEEE802154_PROTOABBREV_WPAN"
(like certain other dissectors) rather than using "wpan";
missmatch --> mismatch
