These functions correspond to vis(), strvis(), and strvisx() but have an
additional argument extra, pointing to a NUL terminated list of characters.
These characters will be copied encoded or backslash-escaped into dst. These
functions are useful e. g. to remove the special meaning of certain
characters to shells.
To implement the new functions, vis underwent a major rewrite. Most functions
now use a central macro, SVIS. Performance increase ~ factor 2.

* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.
the first two items result in the addition of code similar to the
following in various functions:
_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.
This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
