This offesr memory allocation with a packet scope making memory leaks less likely and memory management faster. Add initialization calls for both tethereal and ethereal. Convert the ip_to_str() function to use this and avoid doing the silly rotating buffers thing it previously did. We also need an equivalent set of functions for allocation with capture file scope (free when next capture is loaded) but i dont know where to put the free_all call. svn path=/trunk/; revision=14984

/*
|
|
* XXX - this takes the plugin directory as an argument, because
|
|
* libethereal now has its own configure script and "config.h" file,
|
|
* which is what code in the "epan" directory includes, but we need
|
|
* to define PLUGIN_DIR in the top-level directory, as it's used by,
|
|
* for example, the Makefile for the Gryphon plugin, so it knows
|
|
* where to install the plugin.
|
|
*
|
|
* Eventually, we should probably have an "epan-configure" script
|
|
* (or "libethereal-configure", or whatever), along the lines of what
|
|
* GTK+ and GLib have, that can print, among other things, the directory
|
|
* into which plugins should be installed. That way, only libethereal
|
|
* need know what directory that is; programs using it won't, *and*
|
|
* Makefiles for plugins can just use "epan-configure" to figure out
|
|
* where to install the plugins.
|
|
*
|
|
* (Would that *more* libraries had configure scripts like that, so
|
|
* that configure scripts didn't have to go through various contortions
|
|
* to figure out where the header files and libraries for various
|
|
* libraries are located.)
