Michal Labedzki 579e7e19ce Wireshark: Add option to choose format type of capture file
The best heuristic can fail, so add possibility to manually choose
capture file format type, so not correctly recognize file format can be
loaded in Wireshark.

On the other side now it is possible to open capture file
as file format to be dissected.

Guy Harris c65fbffc95 Force "printing" if -T is specified, even if -w is also specified.
Just as "tshark ... -P -w xxx" writes raw packets to xxx *and* writes
text packet summaries to the standard output, and just as "tshark ...
-V -w xxx" writes raw packets to xxx *and* writes text packet details to
the standard output, so should "tshark ... -T fff -w xxx" write raw
packets to xxx *and* write whatever "-T fff" (and any "-e" options)
specifies to the standard output.

Guy Harris 114d051aef Fix crash when doing "tshark -2 -r file -w newfile".
We were using cf->buf in some places and a local variable buf in others;
consistenly use the local variable.

Have a local variable for the struct wtap_pkthdr while we're at it; with
some work we may be able to get rid of the struct wtap_pkthdr and the
Buffer in the capture_file structure.

Gerald Combs f966980937 Replace "svn" with "git" all over the place.
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.

Guy Harris 90d7c5f59b Don't write out packets that have a "captured length" bigger than we're
willing to read or that's bigger than will fit in the file format;
instead, report an error.

For the "I can't write a packet of that type in that file type" error,
report the file type in question.

Guy Harris 125a17f8e5 Initialize the error-reporting routines before scanning for plugins, as
the code to scan for them uses those routines.

This means epan_init() no longer takes those routines as arguments -
which is just as well, given that the mechanism in question is no longer
part of libwireshark, but is part of libwsutil.

This should fix bug 9508.

Evan Huus 5c851858d9 Fully deprecate read filter (-R) without two-pass (-2). It does exactly the same
thing as the display filter (-Y) in that case except with more confusing
semantics.

This also lets us fix -c in the single-pass case to unconditionally count
packets. This isn't the old behaviour (which counted them only if they passed
the read filter) but is more consistent with two-pass mode where they are
counted even if they pass the display filter, since they are counted on the
first pass and the display filter is applied on the second pass.

Anyone who wants to use -c to limit packet count conditionally on them passing a
filter should use it in tandem with -2 and -R: the read filter is applied on the
first pass before the count.

The limits are enforced during the first pass, and frames that get dropped from
the first pass for this reason aren't available to the second pass at all, so
checking again is redundant.

Evan Huus d8f00e22e1 As suggested in https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9033
Make epan_free a no-op if the pointer is NULL. This fixes 99% of the cases
causing problems for wmem_leave_file_scope() - remove that XXX comment and add
back the assertion.

Remove the cleanup_dissection call from epan_cleanup, it doesn't make sense
there. init_dissection is only called from epan_new, so cleanup_dissection
should only be called from epan_free.

Add one missing epan_free call to tshark revealed by the above changes.

Guy Harris 5c0baee2a9 Don't print the packet counter when capturing if we're also printing
packet information to a terminal (which we assume is the same terminal
as the one to which the packet counts are being printed), as they get in
the way of each other.

Don't print it if we're sending the standard error to a terminal, or if
-q is specified, either.

Put all the setting of print_packet_counts together; it looks as if the
default value of print_packet_counts may have been changed to TRUE and
the code to handle -q wasn't changed to set it to FALSE if -q was
specified rather than setting it to TRUE if it wasn't specified.
