861f9fd7d8 Add xlat description structure. 
Rename struct xlat to struct xlat_data and make struct  xlat an xlat descriptor
that contains various information about xlat. So far, it's type and number
of items.

As a result, xlookup/printxval now have enought information for handling
xlat depending on its type, so no *index/*_search APIs are needed.

* xlat.h (struct xlat_data): Rename from struct xlat.
(struct xlat): New type definition.
* xlat.c (xlat_search, printxval_sized, printxval_searchn_ex, xlat_idx,
printxval_indexn_ex, printxval_dispatch_ex, ): Remove.
(xlookup): Handle xlat_data based on xlat type.
(xlookup_le): New function, replaces xlat_search_eq_or_less and supports
all xlat types.
(sprintflags_ex, printflags_ex): Update.
* xlat/gen.sh (gen_header): Add handling for #sorted, generate new
struct xlat descriptor.
* defs.h (arp_hardware_types_size, ethernet_protocols_size,
inet_protocols_size, evdev_abs_size, xlat_search,
xlat_search_eq_or_less, xlat_idx, printxval_searchn_ex,
printxval_searchn, printxval_search, printxval_search_ex,
printxval_indexn_ex, printxval_indexn, printxval_index,
printxval_index_ex, printxval_dispatch_ex, printxval_dispatch): Remove.
(enum xlat_style_private_flag_bits): Remove PAF_INDEX_XLAT_SORTED_BIT
and PAF_INDEX_XLAT_VALUE_INDEXED_BIT.
(enum xlat_style_private_flag): Remove PAF_INDEX_XLAT_SORTED and
PAF_INDEX_XLAT_VALUE_INDEXED.
(print_array_ex): Remove index_xlat_size argument.
(xlookup_le): New declaration.
(printxval_ex): New macro.
* dyxlat.c (struct dyxlat): Remove used field (use xlat.size instead),
embed struct xlat, add pointer to struct xlat_data.
(MARK_END): Remove.
(dyxlat_alloc, dyxlat_free, dyxlat_get, dyxlat_add_pair): Update in
accordance with the structure changes.
* evdev.c (evdev_abs_size): Remove.
(keycode_ioctl): Use printxval instead of printxval_index.

(decode_bitset_): Rename to decode_bitset, remove decode_nr_size and xt
arguments, call printxval instead of printxval_dispatch.

c0827b1ae9 nlattr: add size check to decode_nla_xval and decode_nla_flags 
If the field size is known, do not print as valid numbers those
attributes that are too short, and ignore extra data.

This change puts xval/flags printing in line with the reset of attribute
decoders.

* nlattr.h (struct decode_nla_xlat_opts): Add size field.
* nlattr.c (decode_nla_xval, decode_nla_flags): Check that len is at
least opts->size, limit len to opts->size.
(decode_nla_ip_proto): Specify size of 1.

79a02d029c nlattr: add value processing support for xlat/flags nlattr decoders 
Needed for upcoming decoder of ethernet proto which is stored in the
host order and has to be converted to the network order before printing
as an xval constant.  This change also adds ability to provide
prefix/suffix in order to enclose the printed value in something that
describes the performed conversion.

* nlattr.h (struct decode_nla_xlat_opts): Add prefix, suffix, and
process_fn fields.
* nlattr.c (decode_nla_xval, decode_nla_flags): Handle process_fn,

dbc5d26b29 nlattr: add ability to pass nla_type to decoder in decode_nlattr 
As of now, it's impossible to introduce a dispatching nlattr decoder
that performs actions based on the type of the message, so let's use
a combination of zero decoder list size and non-zero decoder pointer
for this.

This is going to be used later in IFLA_AF_SPEC decoding.

* nlattr.c (decode_nlattr_with_data): Handle zero size and non-NULL
decoders in a special way.
(decode_nlattr): Add an error message about ignoring of opaque_data
argument when zero size and non-NULL decoders are provided.
