commit 71d7c22f54ae32d15133571e09ddf7ab435e8afa

util: New function ovs_strzcpy().
		
Static analyzers hate strncpy().  This new function shares its property of
initializing an entire buffer, without its nasty habit of failing to
null-terminate long strings.

commit e868fb3d322f5c46385f1fc6db5bb1ab33f90305

util: Don't read over 'size - 1' bytes of source string in ovs_strlcpy().
		
The blind replacement of strncpy() by ovs_strlcpy() is risky because
strncpy() never reads more bytes from its source string than necessary to
write its destination string, but ovs_strlcpy() and the OpenBSD function
that inspired it both read the entire source string.  This avoids that
problem.

Given that change, we can use ovs_strlcpy() in a few more places, and
this commit does that too.
