c119a6da7c getrandom: print string as hex-escaped 
Since there is no reason to interpret the value returned by getrandom as
ASCII string, it makes sense to always print it as a hex-escaped string.

* getrandom.c (SYS_FUNC(getrandom)): Use printstr_ex instead
of printstrn, set QUOTE_FORCE_HEX in user_style parameter in order
to force hex-escaped string formatting.
* tests/getrandom.test: Remove no longer needed -xx flag as the string
is always printed in hexadecimal format now.

89636759d7 Automatically replace PRI_kr[dux] with PRI_kl[dux] 
Remove temporary macros created for transition from long
to kernel_ulong_t.

Automatically replace PRI_kr[dux] with PRI_kl[dux] using
$ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g'

* defs.h (PRI_krd, PRI_kru, PRI_krx): Remove.  All users updated.

a940d1a60f printstr: rename to printstrn, add printstr as a thin wrapper 
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.

* defs.h (printstr): Rename to printstrn.  All callers updated.
(printstr): New static inline function.  All callers updated.
