Return an struct containing error information. This simplifies
the interface to more easily provide richer diagnostics in the future.
Add an error code besides a human-readable error string to allow
checking programmatically for errors in a robust manner. Currently
there is only a generic error code, it is expected to increase
in the future.
Move error location information to the struct. Change callers and
implementation to use the new interface.
Reset tap_listener_queue and tap_dissector_list in tap_cleanup() so that
other cleanup routines (e.g. tap dialog destructors) don't try to access
invalid memory. Fixes#17719.
Instead *_register_plugin() is turned into a noop (with a warning).
The test suit is failing with ENABLE_PLUGINS=Off (it was already failing
before and this patch didn't affect that).
Closes#17202.
Pull the code to register plugin taps, and the loop to register built-in
taps, into a single register_all_tap_listeners() routine.
This leaves it up to libwireshark, not to the programs using it, to know
how to register them.
Adds a pre-commit hook for detecting and replacing
occurrences of `g_malloc()` and `wmem_alloc()` with
`g_new()` and `wmem_new()`, to improve the
readability of Wireshark's code, and
occurrences of
`g_malloc(sizeof(struct myobj) * foo)`
with
`g_new(struct myobj, foo)`
to prevent integer overflows
Also fixes all existing occurrences across
the codebase.

This allows taps that can fail to report an error and fail; a failed
tap's packet routine won't be called again, so they don't have to keep
track of whether they've failed themselves.
We make the return value from the packet routine an enum.
Don't have a separate type for the per-packet routine for "follow" taps;
they're expected to act like tap packet routines, so just use the type
for tap packet routines.
One tap packet routine returned -1; that's not a valid return value, and
wasn't one before this change (the return value was a boolean), so
presume the intent was "don't redraw".
Another tap routine's early return, without doing any work, returned
TRUE; this is presumably an error (no work done, no need to redraw), so
presumably it should be "don't redraw".
Clean up some white space while we're at it.

If remove_tap_listener() doesn't find a tap listener with the specified
data, print a warning message and skip the "remove the tap listener"
steps.
This means that the internal free_tap_listener() won't be called with a
null listener; remove the now-unnecessary check (if anybody *does* call
it with a null pointer, that's a bug).
This prevents the crash in bug 15006, but that now produces a warning
message; it doesn't fix the underlying bug, it just changes the symptom.

load the plugins, and have them scan the appropriate subdirectories
so that we don't even *try* to, for example, load libwireshark plugins
in programs that only use libwiretap.
Compiled plugins are stored in subfolders of the plugin folders, with
the subfolder name being the Wireshark minor version number (X.Y). There is
another hierarchical level for each Wireshark library (libwireshark, libwscodecs
and libwiretap).
The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}.
Currently we only distribute "epan" (libwireshark) plugins.

Have dfilter_compile() take an additional gchar ** argument, pointing to
a gchar * item that, on error, gets set to point to a g_malloc()ed error
string. That removes one bit of global state from the display filter
parser, and doesn't impose a fixed limit on the error message strings.
Have fvalue_from_string() and fvalue_from_unparsed() take a gchar **
argument, pointer to a gchar * item, rather than an error-reporting
function, and set the gchar * item to point to a g_malloc()ed error
string on an error.
Allow either gchar ** argument to be null; if the argument is null, no
error message is allocated or provided.
