include: ssp: round out fortification of current set of headers

ssp/ssp.h needed some improvements:
- `len` isn't always a size_t, it may need casted
- In some cases we may want to use a len that isn't specified as a
parameter (e.g., L_ctermid), so __ssp_redirect() should be more
flexible.
- In other cases we may want additional checking, so pull all of the
declaration bits out of __ssp_redirect_raw() so that some functions
can implement the body themselves.

strlcat/strlcpy should be the last of the fortified functions that get
their own __*_chk symbols, and these cases are only done to be
consistent with the rest of the str*() set.

Update the projects tree to a newer FreeBSD current.

Add restrict qualifiers to the parameters to strlcpy() and strlcat().
The annotation mainly just serves as a hint that they're not intended
for use with overlapping strings.

- License change to a less restrictive one;
- ANSIfy;
- Convert do {} while loop -> while {} for clarity;
- Sync RCS ID with OpenBSD;

o Make grep ^strlcpy work: put a return value type on separate line.

Remove extra closing parenthesis added in revision 1.4.

Back out the `hiding' of strlcpy and strlcat. Several people
vocally objected to this safety belt.

`Hide' strlcpy and strlcat (using the namespace.h / __weak_reference
technique) so that we don't wind up calling into an application's
version if the application defines them.
