Guy Harris ff9f9fc431 Don't include "file.h" if you don't need it.
It ends up dragging in libwireshark headers, which programs not linking
with libwireshark shouldn't do.  In particular, including
<epan/address.h> causes some functions that refer to libwireshark
functions to be defined if the compiler doesn't handle "static inline"
the way GCC does, and you end up requiring libwireshark even though you
shouldn't require it.

Move plurality() to wsutil/str_util.h, so that non-libwireshark code can
get it without include epan/packet.h.  Fix includes as necessary.

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.

Bill Meier 86930ddde2 Given that we allow the 'outfile file' to be stdout, then presumably all
text messages (including informational) should go to stderr.

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 0cc1545d05 Move most of the plugin code from epan to wsutil and remove all
knowledge of particular types of plugins.  Instead, let particular types
of plugins register with the common plugin code, giving a name and a
routine to recognize that type of plugin.

In particular applications, only process the relevant plugin types.

Add a Makefile.common to the codecs directory.
