Summary: Lua: Trying to use Field.new("tcp.segments") to get
reassembled TCP data is failed

Trying to use Field.new("tcp.segments") to get reassembled TCP data is failed.
Try xxx.value or xxx() get nil. I checked the source code, and find the
reason is :
In packet-tcp.c, it set "tcp.segments" field to FT_NONE type;
Then in wslua_field.c, FT_NONE is converted to lua as nil.
My suggestion is to modify wslua_field.c->FieldInfo__call, to convert all
FT_NONE to lua ByteArray just like FT_PROTOCOL that has been converted to
ByteArray in 1.3.4.
Another bug about Field.new("tcp.segments") is xxx.range got "expired tvb"
error too in reassembled tcp packet.
