being COTP packets, so we make "dissect_cotp_internal()" return FALSE if
it saw no valid COTP packets, and return TRUE and set the COL_PROTOCOL
field to COTP if it saw at least one valid COTP packet, and have
"dissect_cotp()" dissect the packet as raw data if
"dissect_cotp_internal()" returns FALSE (for the benefit of callers such
as X.25).

Fix up some spacing problems in the INFO field of CLNP packets.
Dissect only the payload of DT and MD NPDUs as COTP; the payload of
other packets isn't to be so dissected (ER NPDUs are like ICMP error
packets, in that they contain the network-layer header and zero or more
bytes of the payload of the offending packet, for example).

in its caller.
Set the COL_PROTOCOL column to "COTP" in the COTP dissector, rather than
in the dissectors it calls, so that it's done for all frames we hand to
that dissector.
Set the COL_INFO field for COTP packets we don't dissect because the
length indicator is zero, or the frame is too short, or the PDU type is
bogus.

Fix the TPDU code numeric value to be "0x%x" rather than "Ox%x".
Add a COL_INFO field for CLNP PDUs whose payload we don't dissect as
COTP.
Don't dissect segments other than the first derived PDU of a segmented
CLNP PDU (just as we do with fragments other than the first fragment of
a fragmented IP datagram).

Use "%u" rather than a hex format to print length values and segment
offsets, and use "%u" rather than "%d" to print unsigned values.
In the CLNP dissector, chop off the payload and captured-payload lengths
based on the segment length (along the lines of what we do for IP).

If using GCC 2.x, we can check the print-format against the variable args
passed in. Regardless of compiler, we can now check at run-time that the
field type passed into the function corresponds to what that function
expects (FT_UINT, FT_BOOLEAN, etc.)
Note that proto_tree_add_protocol_format() does not require a value field,
since the value of a protocol is always NULL. It's more intuitive w/o the
vestigial argument.
Fixed a proto_tree_add_item_format-related bug in packet-isis-hello.c
Fixed a variable usage bug in packet-v120.c. (ett_* was used instead of hf_*)

Add the plugin_api.[ch] files ot the plugins/Makefile.am packaging list.

"fd->cap_len" for the frame length - or to use macros such as
"BYTES_ARE_IN_FRAME()", "IS_DATA_IN_FRAME()", and "END_OF_FRAME", which
use "pi.captured_len" - so that they correctly handle frames where the
actual data length of the packet is less than the size of the raw frame,
e.g. with encapsulations such as ISL.

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.

the base for numbers to be displayed in, bitmasks for bitfields, and blurbs
(which are one or two sentences describing the field).
proto_tree_add*() routines now automatically handle bitfields. You tell
it which header field you are adding, and just pass it the value of the
entire field, and the proto_tree routines will do the masking and shifting
for you.
This means that bitfields are more naturally filtered via dfilter now.
Added Phil Techau's support for signed integers in dfilters/proto_tree.
Added the beginning of the SNA dissector. It's not complete, but I'm
committing it now because it has example after example of how to use
bitfields with the new header_field_info struct and proto_tree routines.
It was the impetus to change how header_field_info works.

The library exists in its own subdirectory ethereal/wiretap. This patch also
edits all the packet-*.c files to remove the #include <pcap.h> line which is
unnecessary in these files. In the ethereal code, file.c is the most heavily
modified with #ifdef WITH_WIRETAP lines for the optional library.
