Stig Bjørlykke 551745998e wslua: Fix memleak of unregistered ProtoField strings
If a ProtoField object was created, but not linked to a Proto, then the
strings field and all elements (depending on type) would leak.

This is a follow-up to g79fef2ae and fixes the real issue in g44870fb1.

Add the newly create ProtoField to the test_proto.fields in order to be freed.

Stig Bjørlykke 0371994223 wslua: Improve parameter check in ProtoField.new()
Improve paremeter check in ProtoField.new() when using ftypes.CHAR:
- Check valid base types and give an error when not supported instead of
  terminate in a g_error() (base.DEC is not supported).
- Give an error if used with base.UNIT_STRING instead of silently remove
  the flags.
- Support base.RANGE_STRING instead of removing the flag.

Support using base.NONE with a valuestring.
Add ftypes.CHAR to the list of supported types.

Rado Radoulov ae8b18d618 New Lua function TreeItem:referenced(ProtoField | Dissector).
This function returns TRUE/FALSE depending whether the specified ProtoField/Dissector
needs to be dissected. By using this function in conjunction with the TreeItem.visible
attribute, Lua dissectors can be significantly sped up by making less C interop calls
which are relatively slow in terms of dissection especially when using sub-protocols
where the dissection of an entire protocol can be skipped.

Added tests for TreeItem:referenced to protofield.lua
