xlat: add auxval mode to sprintflags_ex
sprintflags is often used to decode flag set returned by a syscall; it,
however, looks somewhat ugly when collided with xlat styles (and even
without it, somewhat superfluous[1] when values that do not match any flags
are printed). Introduce a special mode that makes sprintflags output
more akin to XLAT_STYLE_VERBOSE comment (except when XLAT_STYLE_RAW
is used).
[1] It may be seen useful as the default return value format is decimal
and sprintflags uses hex, but at least fcntl always prints flags in
return values as RVAL_HEX anyway.
* src/defs.h (enum xlat_style_private_flag_bits) <SPFF_AUXSTR_MODE_BIT>:
New flag bit.
(enum xlat_style_private_flags) <SPFF_AUXSTR_MODE>: New flag.
* src/xlat.c (sprintflags_ex): Handle SPFF_AUXSTR_MODE flag in style.
