Evan Huus 681a3ad5a2 Handle NULL-pointers and 0-lengths in a much simpler allocator-agnostic way,
and document the fact that allocator authors don't have to care.

Evan Huus 669b98bb5f Rewrite wmem_allocator_simple to track allocations using a GHashTable instead of
a GSList. This permits it to implement the new realloc and free functions. Also
fill in an empty gc function, since there isn't much it can do as far as
garbage-collection goes.

Evan Huus 21453d5db6 Add three more slots to the wmem allocater definition (not yet implemented
by any particular allocator) and better document the entire structure.

Jeff Morriss 99ce4232cb As suggested in comments in sl_alloc() and sl_free(): add a new environment
variable (WIRESHARK_DEBUG_USE_SLICES) which turns off the slab allocator and uses
g_slices instead (which can themselves be turned off by setting
G_SLICE=always-malloc).

This makes debugging problems in slab-allocated memory easier to find
(hopefully including https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8197 ).


Set WIRESHARK_DEBUG_USE_SLICES when running Valgrind on *shark.


Remove unused structure member: emem_chunk_t.org.

Guy Harris d67586ccc4 Fix description of -p input - show the packet data the same way it's
shown for the previous input format (showing "data" as a pointer is a
bit confusing, as it's just in-line data in the input), and give a more
detailed description of the issues with that file format (the size of
the seconds field of the time stamp is platform-dependent).

running everything under valgrind).

Michael Tüxen 22df071cef Add support for -D option. The preamble will start with
an I or O indicating the direction of the packet. This
will be stored in the generated file if the pcap-ng
format is used.
Thanks to Jaap for suggesting to integrate this into
the preamble!

Michael Tüxen a52b0de406 Add support for writing pcap-ng files by specifying -n as an option.
Leave pcap the default file format for now. The is should be reconsidered
before the next release as it might make sense to use pcapgn as
the default as we do for dumpcap. (We can use the -P option to allow
switching back to pcap).

Jeff Morriss 456acec892 Do a little more to discourage the use of proto_tree_add_text(): don't
use it as example in a few places and point out that if you're not using the
return value to build a subtree, you probably shouldn't be using the function.

Evan Huus 5cf858ec52 Dispatch all allocator creations through a single function using an enum to
determine the desired type. This has two advantages over the old way:
 - just one environment variable for valgrind to override in order to guarantee
   that ALL allocators use memory it can track, and just one place to check that
   variable
 - allocator owners no longer have to include headers specific to their
   allocator, allowing them to change allocators without adjusting all their
   #includes

Jeff Morriss ed87fa9e3b Come down harder on the evils of tvb_get_ptr(): advise not to use it.
Combine the two comments in the Portability section (which largely said the
same thing) on the perils of that function.

Don't suggest it as an option to ensure there are enough bytes in the TVB.

Jeff Morriss 05ee001d73 Document the "-g" option to dumpcap.
Add that option to tshark, too, and document it.

The option can't be given to Wireshark because the GUI already has a "-g"
(goto packet).

Gerald Combs bd19dcd8bf Add an add_hosts_file routine that adds a "hosts" path to an array and
use it in tshark.c instead of read_hosts_file. This lets us use "-H"
multiple times. Make read_hosts_file static.

Jeff Morriss 26a40dd999 editcap does not support the -H and -W options, remove the description of
those options (which had been cut-n-paste from the tshark man page).

For editcap to support these options it would either need to be linked
against libwireshark or the address resolution stuff would need to be moved
from libwireshark to, for example, libwsutil.

Martin Mathieson 3f3743834b This is basically a rewrite from Jakub Zawadzki.
Rather than store the FrameRecord entries in a sorted linked list,
instead use an unsorted GPtrArray, then sort it all at once.

Also, there is no longer the option to limit the amount of sorting (and memory
used), but a new option means we can avoid writing the output file
altogether if the input file is found already to be in order.

fix the perldoc link.  Maybe someone else can figure out how to also fix:

    http contains "http://www.wireshark.org"

Either the hyperlink should be made to work correctly by not including the
trailing quote as part of the link, or simply change it so it's not hyperlinked
at all.  Also, it should display a terminating semi-colon as follows:

    http contains "http://www.wireshark.org";
