the 1003.1-2001 Thread Safe Functions (TSF) getgrnam_r(3) and getpwnam_r(3).
These are not implemented in sysctl(3) "user.*", since that adds a lot
of complexity in the implementation for no real benefit.
The cast just stops gcc detecting places where the functions are
passed a 'char' variable - and will index off the array for byte values
0x80 to 0xff.
All (I hope) of the places in the netbsd sources where this was a
potential problem have had an (unsigned char) cast applied.
Christos said he'll fix any fallout I've missed.
methods use va_list in a manner that is directly related to the public API.
This makes it much easier to write dynamic nsswitch backends for getpwent(3).
Per my proposal on tech-userlevel.
Implement getpwgid_r() and getpwnam_r() APIs per the POSIX 1003.1, 2004 Ed.
These aren't fully reentrant or threadsafe yet, because the compat stuff
currently uses non-reentrant data sources (getnetgrent(3), getpwent(3)),
and there is probably some locking to be improved in the backends.
This will be fixed in the near future.
We also need to add _SC_GETPW_R_SIZE_MAX to sysconf(3).
Fix the compat `+' prototype override so getpwnam(3) and getpwuid(3) DTRT.
Improve the description of pw_class and pw_gecos.

bitrange for nsdispatch(3) return values.
* Tweak documentation comments in nsswitch.h
* Ensure the result from the back-end method is masked with
NS_STATUSMASK before nsdispatch(3) returns it.
but it is specified by IEEE Std 1003.1, 2004 Edition (POSIX) and
the X/Open standards (Issue 6 and XNS 5.2).
* revert change removing gethostent() from gethostbyname(3) man page
* delete kruft from gethnamaddr.c leaving only gethostent() as a
wrapper around _gethtent().
* revert recent changes to <netdb.h>
+ restore gethostent() prototype
+ restore freehostent() prototype; handle similar to non-shipped
getipnodby*() prototypes

and add "errbuf" and "errbufsz" parameters so that errors can be handled
gracefully, rather than simply exiting the process.
- Add a pw_copy() wrapper around pw_copyx() to preserve old behavior for
apps that use it.
- Bump shlib version to 7.4.
Adapted from FreeBSD. Maintains full backward API / ABI compatbility
with built-in-only nsdispatch().
While here, also make nsdispatch() itself thread-safe.
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).
