That's a less gross hack to suppress load failures due to not having
libwiretap than providing a no-op failure-message routine, as it at
least allows other code using a failure-message routine, such as
cmdarg_err() and routines that call it, to be used.
We really should put libwiretap and libwireshark plugins into separate
subdirectories of the plugin directories, and avoid even looking at
libwireshark plugins in programs that don't use libwireshark.

The "-Wwrite-strings" flag produces nuisance warnings. These warnings are
not useful, they're impossible to fix in a sane way and therefore are being
handled with casts of static strings to (char *).
This just moves the warning to [-Wcast-qual] and a compiler pragma is
in turn required (and used) to squelch that warning.
Remove the Wwrite-strings warning. Let that responsibility fall on the
programmer (as is done by casting).

Should fix build issue and none of the current taps are relevant to tfshark
anyways.

Rename "SVNPATH" to "GITBRANCH" since that seems more appropriate.
Rename "svnversion.h" to "version.h" as Evan suggested. Update some
URLs. In make-version.pl, make sure we don't set an improper upstream
branch name. Use the number of commits + short hash from `git describe`
for package names by default.

cast packet_size to unsigned int. Yes, that means that it can't read
more than 65535 bytes.
Clean up white space while we're at it.

This is a VERY PRELIMINARY version of tfshark. It's an attempt to jumpstart FileShark and its architecture. Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it)
This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture. And those layers will slowly be added in time (patches always welcome!).
