This is similar to print_quoted_cstring, but not quite the same.
* tests/print_quoted_string.c (print_quoted_stringn): New function.
* tests/tests.h (print_quoted_stringn): New declaration.
Remove _STR which is essentially the same as STRINGIFY but from
the namespace where we should not introduce new identifiers.
* tests/tests.h (_STR): Remove.
* tests/add_key.c (main): Replace _STR with STRINGIFY.
* tests/keyctl.c (XARG_STR): Likewise.
* tests/request_key.c (main): Likewise.
* tests/Makefile.am (AM_CPPFLAGS): Forward SIZEOF_KERNEL_LONG_T
and SIZEOF_LONG as TESTS_SIZEOF_KERNEL_LONG_T and TESTS_SIZEOF_LONG.

Redefine to TESTS_SIZEOF_KERNEL_LONG_T.

Complements: v4.21~5 ("Export SIZEOF_LONG and SIZEOF_KERNEL_LONG_T to tests")
Quotes are not always used to denote string limits; printfd uses angle
brackets for that, for example. As result, mechanism for supplying
set of additional characters in order to avoid ambiguities regarding
the end of the quoted string is needed.

(print_quoted_string_ex): New function prototype.
* util.c (string_quote): Add escape_chars parameter.
(print_quoted_string_ex): Rename from print_quoted_string, add
escape_chars parameter, pass it to string_quote call.
(print_quoted_string): Turn into a thin wrapper around
print_quoted_string_ex.
(printstr_ex): Pass NULL as escape_chars argument of string_quote call.
* socketutils.c (unix_parse_response): Pass NULL as escape_chars
argument of string_quote call.

escape_chars parameter.

* tests/tests.h [!perror_msg_and_fail] (perror_msg_and_fail): New macro

In many places where kernel expects a NUL-terminated string of length
up to a known fixed limit, e.g. when a NUL-terminated string is
a fixed-size field of a structure, strace does not print the last byte
assuming it is NUL, which is not always the case.
Change output format for such strings to distinguish NUL-terminated
strings from non-NUL-terminated ones: append ellipsis to the output
when the string is not NUL-terminated.

and struct utimbuf.modtime fields, use sprinttime to format a string
