* defs.h (sprintflags_ex): Add "sep" argument.
(sprintflags): Pass '\0' in "sep" argument.
* open.c (sprint_open_modes): Use sprintflags_ex for printing
open_mode_flags.
* xlat.c (sprintflags_ex): Add "sep" argument, use it as initial
separator (if not nul).
For the cases when it is preferable to print something like
"BASE_VAL+increment".
* defs.h (xlat_search_eq_or_less): New declaration.
* xlat.c (xlat_search_eq_or_less): New function.
In order to avoid dealing with xlat verbosity styles outside xlat code
as much as possible.
* defs.h (xlat_style_private_flag_bits): Rename from
print_array_flag_bits, add PXF_DEFAULT_STR_BIT.
(xlat_style_private_flags): Rename from print_array_flags, add
FLAG_(PXF_DEFAULT_STR).
* xlat.c (print_xlat_ex): Handle PXF_DEFAULT_STR by interpreting str
as a default value (print both value and str in XLAT_STYLE_ABBREV).
This is going to be used later in IFLA_AF_SPEC decoding.
* xlat.c (xlookup): Add static variable pos, store xlat there when it is
non-NULL, use pos for lookup.
(xlat_search, xlat_idx): Add static variables pos and memb_left, store
xlat and nmemb there when xlat is non-NULL, use them for lookup.
(printxvals_ex): Store the last non-NULL xlat in static variable "last".
If the first xlat argument is NULL, use "last" instead.

* defs.h (printxval_dispatch_ex): Rename from printxval_dispatch, add
style argument.
(printxval_dispatch): New static inline function, a thin wrapper around
printxval_dispatch_ex.
* xlat.c (printxval_dispatch): Rename to printxval_dispatch_ex, add
style argument, handle it.

There are quite a few xlats that start from 0 and not too sparse,
we can push the search time for them down to O(1).
* defs.h (printxval_indexn_ex): New declaration.
(printxval_indexn, printxval_index, printxval_index_ex): New macros.
* xlat.c (printxval_sized): Rename from printxval_searchn_ex,
add fn argument, call it instead of xlat_search.
(printxval_searchn_ex): Implement as a thin wrapper around
printxval_sized using xlat_search as a search function.
(xlat_idx): New function.
(printxval_indexn_ex): New function, a thin wrapper around
printxval_sized using xlat_idx as a search function.
* xlat/gen.sh: Add support for "#value_indexed" directive.
It allows to use the following code pattern:
print_xlat_ex(val, xlookup(xlat, val), XLAT_STYLE_FMT_D);
* xlat.c (print_xlat_ex): Handle str being NULL: print val instead.

As there are some possible users for it, apparently.
* defs.h (XLAT_STYLE_FORMAT_MASK): Update the value in order to
accommodate XLAT_STYLE_FMT_D.
(enum xlat_style) <XLAT_STYLE_FMT_D>: New enumeration entity.
(printxval64_d, printxval_d): New function, a shorthand for
printxvals_ex with a single xlat and XLAT_STYLE_FMT_D xlat style.
* xlat.c (sprint_xlat_val): Handle XLAT_STYLE_FMT_D.
Since xlat printing routines now have a notion of "style" that should be
used for printing xlat values, we can also employ this argument for
passing information about number printing format (unsigned decimal
or hexadecimal, so far).
* defs.h (XLAT_STYLE_FORMAT_SHIFT, XLAT_STYLE_FORMAT_MASK): New macro
constant.
(enum xlat_style) <XLAT_STYLE_FMT_X, XLAT_STYLE_FMT_U>: New enumeration
entities.
* xlat.c (xlat_verbose, xlat_format): New macro for checking specific
aspect of style argument.
(get_xlat_style): Use xlat_verbose for checking xlat verbosity style.
(sprint_xlat_val, print_xlat_val): New function, for easing printing
raw constant number with respect to printing format style.
(printxvals_ex, sprintxval_ex, printxval_searchn_ex,
printxval_searchn_ex, sprintflags_ex, printflags_ex, print_xlat_ex):
Use xlat_verbose macro for xlat verbosity style checks. Use
print_xlat_val instead of direct raw xlat value printing.
print_xlat_ex prints a named constant in accordance with xlat style
provided, print_xlat is a thin wrapper around print_xlat_ex that passes
stringified constant name as a string and XLAT_STYLE_DEFAULT as a style.
* defs.h (print_xlat_ex): New function prototype.
(print_xlat): New macro, a thin wrapper around print_xlat_ex.
* xlat.c (print_xlat_ex): New function.

This will be needed later, with the introduction of user-configurable
xlat style setting (stored in xlat_verbosity variable).
* defs.h (XLAT_STYLE_VERBOSITY_MASK): New macro constant.
(enum xlat_style) <XLAT_STYLE_DEFAULT>: New enumeration entity.
(xlat_verbosity): New external declaration.
(printxvals, printxval_searchn, printxval_search_ex, sprintxval,
sprintflags, printflags64): Use XLAT_STYLE_DEFAULT instead of
XLAT_STYLE_ABBREV.
* strace.c (xlat_verbosity): New variable.
* xlat.c (get_xlat_style): New function.
(printxvals_ex, sprintxval_ex, printxval_searchn_ex, sprintflags_ex,
printflags_ex): Use it.
* defs.h (printxvals_ex): Rename from printxvals, add style argument.
(enum xlat_style): New enumeration.
(printxvals): New macro, a wrapper for printxvals_ex.
(printxval_searchn_ex): Rename from printxval_searchn, add style
argument.
(printxval_searchn): New macro, a wrapper for printxval_searchn_ex.
(printxval_search_ex): New macro, a wrapper for printxval_searchn_ex.
(sprintxval_ex): Rename from sprintxval, add style argument.
(sprintxval): New macro, a wrapper for sprintxval_ex.
(printflags_ex): Add style argument.
(sprintflags_ex): Rename from sprintflags, add style argument.
(sprintflags): New macro, a wrapper for sprintflags_ex.
(printflags64): Pass XLAT_STYLE_ABBREV as a style in printflags_ex call.
* netlink.c (decode_nlmsg_flags): Pass XLAT_STYLE_ABBREV as a style in
printflags_ex call.
* xlat.c (printxvals_ex): Rename from printxvals, add style argument,
handle it.
(sprintxval_ex): Rename from sprintxval, add style argument, handle it.
(printxval_searchn_ex): Rename from printxval_searchn, add style
argument, handle it.
(sprintflags_ex): Rename from sprintflags, add style argument,
handle it.
(printflags_ex): Add style argument, handle it.

It has only single user and implementation of xlat styles for it would
lead to lots of code duplication.
* defs.h (addflags): Remove declaration.
* mem.c (print_mmap_flags): Convert addflags call into printflags64 with
non-zeroeness flags check.
* xlat.c (addflags): Remove.
