João Valverde 47348ae598 dfilter: Add support for literal strings with null bytes 
Before:
    Filter: frame matches "abc\x00def"
    dftest: \x00 (NUL byte) cannot be used with a regular string.
    	frame matches "abc\x00def"
    	                  ^~~~
    Filter: _ws.ftypes.string == "a string with a \0 byte"
    dftest: \0 (NUL byte) cannot be used with a regular string.
    	_ws.ftypes.string == "a string with a \0 byte"
    	                                      ^~

After:
    Filter: frame matches "abc\x00def"

    Syntax tree:
     0 TEST_MATCHES:
       1 FIELD(frame)
       1 PCRE(abc\0def)

    Instructions:
    00000 READ_TREE		frame -> reg#0
    00001 IF_FALSE_GOTO	3
    00002 ANY_MATCHES	reg#0 matches abc\0def
    00003 RETURN

    Filter: _ws.ftypes.string == "a string with a \0 byte"

    Syntax tree:
     0 TEST_ANY_EQ:
       1 FIELD(_ws.ftypes.string)
       1 FVALUE("a string with a \0 byte" <FT_STRING>)

    Instructions:
    00000 READ_TREE		_ws.ftypes.string -> reg#0
    00001 IF_FALSE_GOTO	3
    00002 ANY_EQ		reg#0 == "a string with a \0 byte" <FT_STRING>
    00003 RETURN

Fixes issue #16156.

Moshe Kaplan 1c3a9af869 Add files with WS_DLL_PUBLIC to Doxygen 
Add @file markers for most files that
contain functions exported with
WS_DLL_PUBLIC so that Doxygen will
generate documentation for them.

João Valverde 925e01b23f Remove duplicate format_size() function 
We have two format_size()s, with and without wmem scoped memory.
Move the wmem version to wsutil and add a convenience macro to
use g_malloc()ed memory.

João Valverde 7f9c1f5f92 Move wmem to wsutil 
This allows wmem to be used from other libraries, namely wsutil.
It is often the case that a funtion exists in wsutil and cannot
be used with a wmem scope, requiring some code duplication or
extra memory allocations, or vice-versa, code in epan cannot be
moved to wsutil because it has a wmem dependency.

To this end wmem is moved to wsutil. Scope management remains part
of epan because those scope semantics are specific to dissection.
