Slightly adjust code logic: we allocate a "size"ed length of memory, not
size+1. Use strlcpy() to avoid using - 1 as length for strncpy().

Use strlcpy() before strlen() instead of strncpy().

Since we are going to strlen() on the string, it is supposed to be
NUL-terminated, so use strlcpy() instead of strncpy() here.

Replace malloc() + memset() with calloc. This corrects a misuse of
memset() as a side effect.

Reduce code duplication: use calloc instead of allocing and memset
afterward.

Removing startup banner.

These are the things that the tinderbox has problems with because it
doesn't use the default CFLAGS which contain -fno-strict-aliasing.

Until the code is cleaned up, just add -fno-strict-aliasing to the
CFLAGS of these for the tinderboxes' sake, allowing the rest of the
tree to have -Werror enabled again.

Remove file which was accidently repo-copied to the wrong destination
file-name. The file will be nuked entirely from the repository later.

Typo.

Reword a sentence modified in my previous commit. This new one is probably
better.

Hinted by: ceri

Follow FreeBSD mdoc(7) conventions:
- Remove hard sentence breaks;
- Avoid using double negatives or "sexist" language;
- Expand contractions;
- Remove a blank line;
- Some grammar changes.

Usually we do not "hard code" requests to submit bugs to the author, but
I will leave this go for now.

- Extend the nsswitch to support Services, Protocols and Rpc
databases.
- Make nsswitch support caching.
