_SC_SEM_NSEMS_MAX. Report no limit for getconf(3). The ressource is
naturally limited by the backing file descriptor, so no separate limit
is necessary. Keep the accounting for debugging as it is part of the
sysctl ABI exposed by the kernel.

sched_setparam: fix the case when incorrect (according to the class)
in-kernel priority is used. Reported by <drochner>.
Minor fixes for scheduling calls to conform the POSIX:
- If pid is equal to zero, use the calling process;
- In case of permission problem, return EPERM instead of EACESS;
- sched_setscheduler() should return previously used policy;
- pthread_* calls should return the error code or zero;
Should fix the namespace problems (and builds of some packages):
- Move cpuset_t defintion from pset.h to sched.h;
- Remove the #include of pset.h in pthread.h;

bjh21 | Version times() so that programs compiled before the recent change to make
sysconf(_SC_CLK_TCK) return hz will work.
In detail:
__times13() returns values scaled by hz.
times() returns values scaled by 100.
<sys/times.h> renames times() to __times13().
_SC_CLK_TCK has changed from 3 to 39.
sysconf(3) returns 100.
sysconf(39) returns hz.
CLK_TCK is defined as sysconf(39).
|

perry | make sysconf(_SC_CLK_TCK) return the kernel hz value, instead of a
fixed constant, as is done on Solaris, Linux, etc.
Technically, standards don't *require* this, but having it return a
constant is a violation of the spirit, and screws up programs that
(perhaps improperly) assume that it will return kernel hz.

| 21-Jul-1997 |
jtc | If port provides __weak_alias(), provide an Standard C and POSIX pure
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>.
