printing the blurb twice, like fields2 does.
Add a script, fsanity.py, to check sanity of FT definitions. Right now the
only check is for bitmasks for integer-like fields.

Add a comment to proto_item_append_string() explaining the "danger" and what needs to be done if one decides to use proto_item_append_string()
Add a small change to WSP so that it will disable this speed optimization so not to trigger a DISSECTOR_BUG in proto_item_append_string()

values that may not be valid (e.g. dissect_ber_octet_string()
in packet-ber.c). If the length is invalid, get_uint_value() or
get_int_value() will abort. Change them to throw an exception instead.
This keeps us from having to do a lot of extra work in the dissector.
Fixes bug 182.

Not all proto_item* fields have a subtree associated to it.
If it doesnt have a subtree fi will be NULL,
test fi for NULL before trying to dereference it to avoid a coredump.

It should not dump core as far as all my tests are concerned and Menu_Statistics/ProtocolHierStats work
It needs more testing and there might still be cases where it will crash that will need to be fixed but I feel it will be worth it since it will decrease the time to filter very large capture files dramatically.
Real significant performance boost for very large captures.
(If we cant fix all the problems we can just revert this patch)

"PROTOABBREV A name for the protocol for use in filter expressions;
it should contain only lower-case letters, digits, and
hyphens."
In proto_register_protocol(), generate a warning if PROTOABBREV contains
invalid characters. Along with the list above, allow underscores and
periods. Fix up whitespace.
Lower-case PROTOABBREV in several dissectors.

length values (other than -1) as very large positive values, and for
values larger than the amount of data remaining in the tvbuff, clip the
value to the length of the tvbuff, so that dissectors don't have to
worry about doing that clipping themselves.

"alloc_field_info()", so the error report can include the field with the
problem. (The file and line number isn't interesting - the bug isn't in
"alloc_field_info()", it's in the dissector that called the routine
calling "alloc_field_info()" - but the field name/abbrevition is
interesting, as it'd help developers identify the place in the dissector
where we're passing in a bogus length.)

Add a DISSECTOR_ASSERT() macro, which is the usual type of assertion
macro, but throws a DissectorError exception with a message giving the
flien and line number and the failed test as a string. Use that macro
in "alloc_field_info()".
Report that exception in the Info column and the protocol tree, as well
as logging the exception failure with g_warning().

In the past: to prevent duplicate protocol names (and alike), each time a new protocol was registered, the list of protocols were iterated and the name compared with each existing name using strcasecmp, which is slow as we have >500 protocols right now.
Now: the protocol name to check against duplicates is first converted into a hashvalue and then only this value is checked and stored in a hashtable. This way the string to check for, has to be converted/compared only a single time!

Clean up indentation.
If we dissect an octet string and then re-dissect it as a particular
type of data, don't use the end offset from the re-dissection as the
offset of the end of the octet string - just use the result of
"dissect_per_octet_string()".

integers.
Make FT_INT64 and FT_UINT64 add numerical values, rather than byte-array
values, to the protocol tree, and add routines to add specified 64-bit
integer values to the protocol tree.
Use those routines in the RSVP dissector.

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

"SLAB_ITEM_TYPE_DEFINE()" macro to define a union of the type of object
for the slab and a pointer to an object of that union type, and use that
type for items on the slab allocator free lists; that *should* avoid
having the compiler think two pointers to an item being added to or
removed from the free list don't point to the same object just because
they have different types.
