basic: nicer xsprintf and xstrftime assert messages
It's nicer if the assertion failure message from a bad use of xsprintf
actually mentions xsprintf instead of the expression the macro is
implemented as.
The assert_message_se macro was added in the previous commit as an
internal helper, but it can also be used for customizing assertion
failure messages like in this case.
Example:
char buf[10];
xsprintf(buf, "This is a %s message.\n", "long");
Before:
Assertion '(size_t) snprintf(buf, ELEMENTSOF(buf), "This is a %s
message.\n", "long") < ELEMENTSOF(buf)' failed at foo.c:6, function
main(). Aborting.
After:
Assertion 'xsprintf: buf[] must be big enough' failed at foo.c:6,
function main(). Aborting.
