5723e501ab `Hide' strlcpy and strlcat (using the namespace.h / __weak_reference
technique) so that we don't wind up calling into an application's
version if the application defines them.

c14d379de1 When using `compat' mode, be sure to re-dispatch setpwent, endpwent,
setgrent, and endgrent also.  (The previous NSS implementation used to
simply twiddle the internal data of the various modules directly.)

A symptom (group list set incorrectly in sshd) was

e2527daf1a In compat mode, we `redispatch' the lookup. It is probably a good
idea to re-initialize `struct passwd', because e.g. pw_class might
get set by one module, but not by another.  Add another call to the
internal pwd_init function to accomplish this.

5460b1abd2 ``Strong typing is a crutch for people with weak memories.''
Correct a bug that should have wreaked havoc everywhere, but for
some reason only bit unlucky people who use `-march' optimizations.
The compiler cannot assist one in distinguishing between the two
function calls below.

   int nsdispatch(void *, ...);
   void *discard;

   nsdispatch(&discard, ...);  /* correct .. no, really! */
   nsdispatch(discard, ...);   /* Boom                   */

4c3c0fecae Don't use `memset' to initialize a struct passwd. A module
may not fill in all fields, and in the case of string fields, this could
cause trouble for applications.  (The only likely example is `pw_class',
because this field is not used by all modules in all cases.)

Move initialization of struct passwd from module-specific code to the
dispatch code.

The problem of a NULL pw_class was

05f98035ee = Implement thread-safe versions of the getpwent(3) and getgrent(3)
family of functions using the new nsdispatch(3) core.  Remove
  arbitrary size limits when using the thread-safe versions.

= Re-implement the traditional getpwent(3)/getgrent(3) functions on
  top of the thread-safe versions.

= Update the on-disk format of the hashed version of the passwd(5)
  databases to allow for versioned entries.  The legacy version is
  `3'.  (Don't ask.)

= Add support for version `4' entries in the passwd(5) database.
  Entries in this format are identical to version 3 entries except
  that all integers are stored as 32-bit integers in network byte
  order (big endian).

= pwd_mkdb is updated to generate both version 3 and version 4
  entries.

46d9306383 = Implement name service switch modules (NSS modules). NSS modules
may be built into libc (`static NSS modules') or dynamically loaded
  via dlopen (`dynamic NSS modules').  Modules are loaded/initialized
  at configuration time (i.e.  when nsdispatch is called and nsswitch.conf
  is read or re-read).

= Make the nsdispatch(3) core thread-safe.

= New status code for nsdispatch(3) `NS_RETURN', currently used to
  signal ERANGE-type issues.

= syslog(3) problems, don't warn/err/abort.

= Try harder to avoid namespace pollution.

= Implement some shims to assist in porting NSS modules written for
  the GNU C Library nsswitch interface.

o Add __double_t and __float_t to <machine/_types.h>, and provide
  double_t and float_t typedefs in <math.h>.
o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF,
  HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to
  <math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via
  <machine/float.h>.
o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based
  on the size of its argument.  __fpclassifyl() is never called on
  alpha because (sizeof(long double) == sizeof(double)), which is good
  since __fpclassifyl() can't deal with such a small `long double'.
