João Valverde 1a32a75a62 ftypes: Internal headers need to be internal
The header ftypes-int.h should not be used outside of epan/ftypes
because it is a private header.

The functions fvalue_free() and fvalue_cleanup() need not and should
not be macros either.

João Valverde 92285e6258 dfilter: Improve grammar to parse functions
A function is grammatically an identifier that is followed by '(' and ')'
according to some rules. We should avoid assuming a token is a function
just because it matches a registered function name.

Before:
  Filter: foobar(http.user_agent) contains "UPDATE"
  dftest: Syntax error near "(".

After:
  Filter: foobar(http.user_agent) contains "UPDATE"
  dftest: The function 'foobar' does not exist.

This has the problem that a function cannot have the same name
as a protocol but that limitation already existed before.

Dario Lombardo c3d198c401 dfilter: add string() function.
This function can convert non-string fields into strings. This allows the
user to apply string functions (like contains and matches) to non-string fields.

Examples:

string(frame.number) matches "[13579]$" => for odd frames
string(eth.dst) matches "aa\.bb\.cc\.dd\.ee\..." => to match a group of stations
string(snmp.name) matches "^1.2.3.4" => for all OIDs under a specific node

Guy Harris cfcbb28671 Clean up ftype-conversion and dfilter error message string handling.
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.

Guy Harris cb16dff992 Get rid of more tvb_get_nstringz* calls.
Add an FT_STRINGZPAD type, for null-padded strings (typically
fixed-length fields, where the string can be up to the length of the
field, and is null-padded if it's shorter than that), and use it.  Use
IS_FT_STRING() in more cases, so that less code needs to know what types
are string types.

Add a tvb_get_stringzpad() routine, which gets null-padded strings.
Currently, it does the same thing that tvb_get_string_enc() does, but
that might change if we don't store string values as null-terminated
strings.

Guy Harris 409dd075c6 Replace fvalue_ftype() with a fvalue_type_ftenum() routine that returns
the ftenum_t for the fvalue's ftype, rather than a pointer to the ftype
(which isn't all that useful except as a handle, unless you import the
internal header).

Have fvalue_to_string_repr() return NULL, rather than failing, if the
fvalue's ftype has no val_to_string_repr method.

This lets us not include the ftypes internal header in
ui/cli/tap-diameter-avp.c.
