stdinc: Let Clang static analysis see more C runtime functions.

For systems without strlcpy and strlcat, just declare them as if they exist;
the analyzer possibly still knows the details of these functions and can
utilize that in its analysis.

Most of this patch was from meyraud705 at gmail and Martin Gerhardy. Thanks!

Fixes Bugzilla #5163.
