syslogd after we called openlog(), we don't just to lose until we call
openlog() again. Or get restarted. This is good for long running
processes that use syslog(), like sendmail, postfix, named, etc.
the argument, instead of va_list. Might not make a difference on most
ports, depending on toolchain/MD typedefs. Does make a difference on sparc64,
where it wouldn't compile otherwise.
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>.
