replace tvb_raw_offset() which is essentially a simple assignment and which
is called a lot with a macro.
this makes my tethereal testcase 2-3% faster.

when adding them to the free list, cast the pointer to the structure to
a pointer to a "freed_item_t" which contains the "next" pointer.
This reduces the memory requirement for some of those structures, and
leaves us free to slab-allocate structures that have a "next" pointer
for other reasons.

There might be a 4 (not 2) byte datalen high field.
If there is no such field (due to an early dialect being used) these bytes are often 0xff.
If these four bytes are all 0xff dont display them in the tree.

last columns, if any, with that format, and use that to speed up
processing of columns with a particular format and checking whether
we're displaying a column with a particular format.

structure, rather than separately allocating "fvalue_t"s and having the
"field_info" structure point to them - this appears to speed up protocol
tree construction a bit.

errors when reading the header as indications that the file isn't an
AiroPeek V9 file.
Put in comments nothing some additional checks we should do.

of time in "find_protocol_by_id()"; the protocol_t pointer for a
protocol doesn't change over time, so get that pointer when the protocol
is registered and save it.

so that we can change tvb_get_ds_tvb() into a macro.
This function was a single line assignment and was called a lot.
This made tethereal ~2.5% faster in one testcase I use.

Correct several problems with zoneset decodes (e.g. the zoneset
and zone name lengths do *not* include the pad bytes, so the
offset calculation needed to be fixed).
Move the decode of zoneset name into the routine
"dissect_fcfzs_zoneset", so that it is done in only one place.

like "decode_enumerated_bitfield()" but handles value_string tables
containing values as they appear in the bitfield rather than as they
appear in the item containing the bitfield.

add a message statistics tap for ANSI A interface for Tethereal;
fix the BSSAP, BSMAP, and DTAP interface dissectors to call
subdissectors even if no protocol tree is being built.

"construct_args_t" is for use with filter dialogs, and the members other
than the title apply only to filter dialogs.
Have "select_file_cb()" actually use the title supplied to it.
svn path=/trunk/; revision=9125
rename it to select_file_cb to reflect its function.
While this cleans things up a bit, I am still not happy because now
filter_prefs.h must be included before file_dlg.h just to get
construct_args_t.

data to a file. This allows the user to select some stuff, and analyse it with
external tools, and is very useful for quickly prototying dissectors etc.
This works by retrieving the info that is needed to define where the selected
region is.
It puts up a dialog box that asks for the file to save in.
However, it is an ugly hack, because it reuses print_file_cb, while
print_file_cb should be moved into file_dlg.c.
It also needs to have some warning dialogs put up in error cases.
Finally, it would be good to be able to select a region in the byte_view,
which you can do with click and drag, and then have a menu item to save the
selected bytes.
