kernel: use gettime(9)/getuptime(9) in lieu of time_second(9)/time_uptime(9) time_second(9) and time_uptime(9) are widely used in the kernel to quickly get the system UTC or system uptime as a time_t. However, time_t is 64-bit everywhere, so it is not generally safe to use them on 32-bit platforms: you have a split-read problem if your hardware cannot perform atomic 64-bit reads. This patch replaces time_second(9) with gettime(9), a safer successor interface, throughout the kernel. Similarly, time_uptime(9) is replaced with getuptime(9). There is a performance cost on 32-bit platforms in exchange for eliminating the split-read problem: instead of two register reads you now have a lockless read loop to pull the values from the timehands. This is really not *too* bad in the grand scheme of things, but compared to what we were doing before it is several times slower. There is no performance cost on 64-bit (__LP64__) platforms. With input from visa@, dlg@, and tedu@. Several bugs squashed by visa@. ok kettenis@

idgen32(9): use time_uptime(9) for rekey timestamps, not time_second(9) Timestamp contexts with a monotonic clock. time_second(9) can jump, stretching or truncating our rekey interval. time_uptime(9) will not jump around. ok djm@

fix a bug that caused time-based rekeys to happen too frequently. rename the structure internals to id32_* in anticipation of an idgen16() that might come in the future.

Introduce a facility to generate unpredictable 32 bit numbers with near maximal (2^32) cycle times. These are useful for network IDs in cases where there are negative consequences to ID prediction and/or reuse. Use the idgen32() functions to generate IPv6 IDs and NFS client/server XIDs. Pseudorandom permutation code in crypto/idgen.c based on public domain skip32.c from Greg Rose. feedback & ok thib@ deraadt@
