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.

The FieldInfo metamethod for equality (letting you use the '==' operator)
doesn't check for equality, but rather if the left-hand side is within
the right-hand side. It should be equality instead. Also, all of the
FieldInfo operate overloads should push a boolean even if they're false
result.

This is substantially more memory-efficient, shaving another ~1.5MB off our base
usage. It also lets us remove the annoying extra "last_field" pointer and
simplify proto_register_field_common(). It also accidentally fixed what may
have been a memory leak in proto_unregister_field().
It unfortunately complicates proto_get_next_protocol_field() to require
refetching the protocol each time, but that is itself just an array-lookup under
the covers (and isn't much used), so I don't expect the performance hit to be
noticable.

This commit adds tvb_get_string_bytes and proto_tree_add_bytes_item routines for
getting GByteArrays fields from the tvb when they are encoded in ASCII hex string form.
The proto_tree_add_bytes_item routine is also usable for normal
binary encoded byte arrays, and has the advantage of retrieving
the array values even if there's no proto tree.
It also exposes the routines to Lua, both so that a Lua script can take
advantage of this, but also so I can write a testsuite to test the functions.

This enhances the Lua API doc generator Perl script to handle
meta-information in description comments, such as bold, italics,
raw code, version info, etc.
The supported markup and codes are documented in make-wsluarm.pl.
It's not beautiful Perl code (I don't know Perl), and I'd rather
do it using Lua, but I think keeping it Perl makes more sense in
the long run.

as some tests for them in the testsuites. Also, functions have been added to allow
a script to get all the available tap types and filter fields, since they are
not exactly what one can see in the Wireshark gui.

Over time the various wslua classes/functions have gotten moldy, with different
ways of doing similar things. Some of it can't be changed without breaking
backwards compatibility for Lua scripts, so I didn't do that. But I did what
I could. The biggest change is a refactoring of how accessors/attributes
are handled in the code, so that most of them work the same way using the
same code.
Specific changes made:
* Added null/expired checking macro to class declarations for many classes
* Removed extraneous pointer/expired checking, since checkFoo() does that already
* Fixed "errors" reported by clang static analyzer; they were false positives, but it was easier to get it to stop complaining by changing the code
* Moved internal wslua functions from wslua_utils.c into a new 'wslua_internals.c' file
* Changed Listener/NSTime/Pinfo/Proto to use a common setter/getter accessor/attribute code model, instead of each of them doing their own
* Fixed some API doc mistakes, mostly around attributes that were documented as read-only but were actually read-write

usefulness, working around bug #9162 until Lua 5.3 is released.
The existing Int64 and UInt64 classes provide virtually no
usefullness, other than for creating a string of their value. While
one could then write Lua code to convert the string to Lua numbers and
such, ultimately Lua has no native 64-bit integer support, making such
a task difficult to handle in Lua. This change adds a host of
functions and operators to the existing Int64 (gint64) and UInt64
(guint64) classes, to enable true 64-bit integer support on par with
native Lua numbers.
A test script is also provided, which tests the functions/operators.

When a new Field is created, does as following:
* Check whether that field is registered, by using `proto_registrar_get_byname`. This is current behavior.
* (patched) If not registered, check whether that field is defined in LUA and will be registered. This is performed in `wslua_is_field_available` accessing LUA context.
* If not, an error "a field with this name must exist" occurs.

Iterate backwards through the linked list of identically-named fields in the lua
bindings since the list is, in fact, created backwards by
proto_register_field_init(). There is some question about whether that is
actually intended, but the rest of the code seems to assume it's normal so we
will too. It was possibly a performance consideration, though that's not
well-documented if so.
Either way, this is the simplest and safest method of fixing the issue with the
lua bindings. See the bug for more analysis.

Fix the Lua tostring() method on FieldInfo objects such that it always returns
a string, although the string might be '(unknown)', '(none)', or '(n/a)'. This
is more conformant to Lua's API style.
Also create a new 'FieldInfo.display' accessor table member, which Lua
scripts can use instead of tostring() to get what the GUI displays.
From me:
Misc indentation fixes, remove redundant 'return' statement.
