Changes:
- All messages now have a checksum (and not only version and verack).
- In the version message: user agent added as a string preceded by a varint length.
- Port in an address is in little endian and not big endian.
- In the version message the receiving and emitting address where inverted.

resizable. Get rid of the group box -- the OS X and Windows HIGs
discourage its use and I'm not sure if it fits the GNOME HIG in this
case either. Make the stream contents monospace. Set the cursor to the
beginning of the text when we follow a stream.
Continue the War On Unnecessary Dialogs. Move "Find"ing from a pop-up
window to the main Follow dialog. Wrap back to the beginning as needed.
Add a "Cancel" button. Make sure it and the escape key work as expected.

time in order to fill in their respective context menus. R52386 broke
that. Fix it and add comments about handling reparenting. Fixes bug
9265.

don't assign the output of pntoh24() to a gint16
unfortunately, vwr detection does not work reliably and many pdf files
are recognized as vwr - this commit should prevent wireshark from
crashing when it tries to load the USB 2.0 spec as pdf ;-)

- fix a typo
- Add the library dirs and not just the libraries.
This would help if the paths that are now returned
were actually correct.

proto_tree_add_item was valid *before* we short-circuited based on a NULL tree.
This was good in that it removed a common source of really-long-loop bugs. It
was less good in that it cost us about 8% in speed when doing a tree-less
dissection, but we decided the tradeoff was worth it.
After Anders' recent mail to -dev about performance, I started thinking about
how to optimize this. It occurred to me that the vast majority of the logic
involved in the check was dealing with the length value - fetching the actual
length if it was a counted string, calculating the length if it was -1, adding
the length to the offset in a way that was free from overflows, etc.
All of this is (theoretically) unnecessary - simply checking the offset without
worrying about the length will still catch the very-long-loops, since it is the
offset that increases in each iteration, not the length.
All that to justify:
- implement tvb_ensure_offset_exists which throws an exception if the offset is
not within the tvb
- use it instead of all the complicated other logic in the pre-short-circuit
step of proto_tree_add_item and friends
This gives us back about 3/4 of the performance we lost in the original patch.
We're still ~2% slower than without any check, but this is the best I can think
of right now.

dissecting without tree, they are costly because they now happen for every
proto_tree_add_item call even if tree is NULL.

tree_data and reference it directly when allocating/freeing tree items. This
lets us keep multiple around when we need them, and still lets us use
wmem_free_all for a major speedup. It also, coincidentally, lets us get rid of
the annoying fi_tmp hack that was needed before, since that element gets swept
up in the free_all with everything else.
Keep one pool cached to avoid creating/destroying a pool for each packet,
another minor performance win.
The various changes in approach seem to balance out pretty much exactly, this
still gives ~11% over pre-52569.

field_info separately. We still have to walk the tree in order to free certain
fvalues, but that's not a big deal. Another ~11% speed-up running "tshark -nVr"
on a large capture.
svn path=/trunk/; revision=52569
Even without making use of free_all (which should be possible) this still
results in ~8% speedup running "tshark -nVr" on a large file in my tests.
svn path=/trunk/; revision=52568
Add a new strutil function format_text_chr that replaces unprintable characters
with a single passed-in char (eg a '.' or a '-') instead of a C-style escape.
This is useful for displaying binary data that frequently but not always
contains text; otherwise the number of C escape codes makes it unreadable.
