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).

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>.

* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * 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

Since CLK_TCK is now a macro expanding into a function call, cache its output instead of using it willy nilly.
