Convert ethertype() and dissect_null() to use tvbuff.

Note in AUTHORS file that we use the exception module from kazlib.

in tvbuff terminology). This is implemented for TVBUFF_REAL and TVBUFF_SUBSET
so far; support for TVBUFF_COMPOSITE is coming soon.
Throw either ReportedBoundsError or BoundsError.
A ReportedBoundsError is reported as "Malformed Frame" since the protocol
stated that a certain number of bytes should be available but they weren't.
A BoundsError is reported as a "Short Frame" since the snaplen was too short.
Register proto_short (BoundsError) and proto_malformed (ReportedBounds)
so searches can be made on "short" and "malformed".

Non-tvbuff dissectors create a tvbuff when calling dissect_llc()
Changed name of current_proto to match string in COL_PROTO ("FDDI" instead of "fddi")
Changed short text to be: [Short Frame: %s] where %s is current_proto.

Add exceptions routines.
Convert proto_tree_add_*() routines to require tvbuff_t* argument.
Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as
the tvbuff_t* argument to proto_tree_add_*() routines.
dissect_packet() creates a tvbuff_t, wraps the next dissect call in
a TRY block, will print "Short Frame" on the proto_tree if a BoundsError
exception is caught.
The FDDI dissector is converted to use tvbuff's.

sub-dissector table is not stored in the header_field_info struct, but
in a separate namespace. Dissector tables are now registered by name
and not by field ID. For example:
udp_dissector_table = register_dissector_table("udp.port");
Because of this different namespace, dissector tables can have names
that are not field names. This is useful for ethertype, since multiple
fields are "ethertypes".
packet-ethertype.c replaces ethertype.c (the name was changed so that it
would be named in the same fashion as all the filenames passed to make-reg-dotc)
Although it registers no protocol or field, it registers one dissector table:
ethertype_dissector_table = register_dissector_table("ethertype");
All protocols that can be called because of an ethertype field now register
that fact with dissector_add() calls.
In this way, one dissector_table services all ethertype fields
(hf_eth_type, hf_llc_type, hf_null_etype, hf_vlan_etype)
Furthermore, the code allows for names of protocols to exist in the
etype_vals, yet a dissector for that protocol doesn't exist. The name
of the dissector is printed in COL_INFO. You're welcome, Richard. :-)

This change allows you to add a new packet-*.c file and not cause a
recompilation of everything that #include's packet.h
Add the plugin_api.[ch] files ot the plugins/Makefile.am packaging list.
Add #define YY_NO_UNPUT 1 to the lex source so that the yyunput symbol
is not defined, squelching a compiler complaint when compiling the generated
C file.

whether we're building a protocol tree or not.
Make "dissect_eth()" use "BYTES_ARE_IN_FRAME()" to see if we have a full
Ethernet header - it can be called with a non-zero offset, if Ethernet
frames are encapsulated inside other frames (e.g., ATM LANE).
Make capture routines take an "offset" argument if the corresponding
dissect routine takes one (for symmetry, and for Cisco ISL or any other
protocol that encapsulates Ethernet or Token-Ring frames inside other
frames).
Pass the frame lengths to capture routines via the "pi" structure,
rather than as an in-line argument, so that they can macros such as
"BYTES_ARE_IN_FRAME()" the way the corresponding dissect routines do.
Make capture routines update "pi.len" and "pi.captured_len" the same way
the corresponding diseect routines do, if the capture routines then call
other capture routines.
Make "capture_vlan()" count as "other" frames that are too short, the
way other capture routines do.

dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:
obviates the need to update "packet.h" whenever you add a new
subtree type - you only have to add a call to
"proto_register_subtree_array()" to a "register" routine and an
array of pointers to "ett_", if they're not already there, and
add a pointer to the new "ett_" variable to the array, if they
are there;
would allow run-time-loaded dissectors to allocate subtree types
when they're loaded.
