LinuxKPI: Implement strscpy
strscpy copies the src string, or as much of it as fits, into the
dst buffer. The dst buffer is always NUL terminated, unless it's
zero-sized. strscpy returns the number of characters copied (not
including the trailing NUL) or -E2BIG if len is 0 or src was
truncated.
Currently drm-kmod replaces strscpy with strncpy that is not quite
correct as strncpy does not NUL-terminate truncated strings and
returns different values on exit.
Seems like an overall useful function, maybe it deserves wider
availability via libc?
