Moshe Kaplan 4a8da5fbde wslua: Fix crash on TvbRange:__tostring for a zero-length TVB
Fields such as 'frame.time_delta' have no byte selection, they are added
with offset 0 and length 0, and evidently 'ws_tvb' is NULL. As
tvb_bytes_to_str expects a non-NULL tvb, explicitly check for this and
add a dummy placeholder. This is intended to be a human-readable string,
so prefer `<EMPTY>` over an empty string.

Gerald Combs ef01359849 Add support for protocol aliases. Switch BOOTP to DHCP.
Add support for aliasing one protocol name to another and for filtering
using aliased fields. Mark aliased fields as deprecated.

Rename the BOOTP dissector to DHCP and alias "bootp" to "dhcp". This
lets you use both "dhcp.type" and "bootp.type" as display filter fields
without having to duplicate all 500+ DHCP/BOOTP fields.

To do:
- Add checks to proto.c:check_valid_filter_name_or_fail?
- Transition SSL to TLS.
- Rename packet-bootp.c to packet-dhcp.c?

Hadriel Kaplan 281055af9c Lua: add functions for more field information
Add Lua functions so a plugin can introspect field information, such
as the type of field, flags, tvb, etc. Also add a couple of Tvb and
ByteArray methods. And cleanup the TreeItem code a little.

Hadriel Kaplan fe769e7350 Add 4 more test scripts for Lua, and its own testsuite menu
This adds test scripts for verifying Pinfo, Address, Field, FieldInfo, NSTime
and Listener classes/functions.  It also moves Lua test scripts out of
unittests and into its own new testsuite.
