This makes output a bit shorter and nicer. For us, shorter output is generally
better.
Also, drop unnecessary UINT64_C macros. The left operand is always uint64_t,
and C upcasting rules mean that it doesn't matter if the right operand is
narrower or signed, the operation is always done on the wider unsigned type.

So far DECIMAL_STR_MAX() overestimated the types in two ways: it would
also adds space for a "-" for unsigned types.
And it would always return the same size for 64bit values regardless of
signedness, even though the longest maximum numbers for signed and
unsigned differ in length by one digit. i.e. 2^64-1 (i.e. UINT64_MAX) is
one decimal digit longer than -2^63 (INT64_MIN) - for the other integer
widths the number of digits in the "longest" decimal value is always the
same, regardless of signedness. by example: strlen("65535") ==
strlen("32768") (i.e. the relevant 16 bit limits) holds — and similar
for 8bit and 32bit integer width limits — but
strlen("18446744073709551615") > strlen("9223372036854775808") (i.e. the
relevant 64 bit limits).
Let's fix both misestimations.

This converts to TEST macro where it is trivial.
Some additional notable changes:
- simplify HAVE_LIBIDN #ifdef in test-dns-domain.c
- use saved_argc/saved_argv in test-copy.c, test-path-util.c,
test-tmpfiles.c and test-unit-file.c

Also, make sure STRLEN works with wide strings too.

When those two macros were used together in CONST_MAX(), gcc would complain
about a type mismatch. So either DECIMAL_STR_MAX() should be made size_t like
STRLEN(), or STRLEN() be made unsigned.
Since those macros are only usable on arguments of (small) fixed size, any type
should be fine (even char would work…). For buffer size specifications, both
size_t and unsigned are OK. But unsigned was used for DECIMAL_STR_MAX macros
and FORMAT_foo_MAX macros, making STRLEN the only exception, so let's adjust
STRLEN() to be unsigned too.
Also: I don't think this is currently used anywhere, but if any of those macros
were used as an argument to sprintf, size_t would require a cast. ("%*s"
requires an int/unsigned argument.)
