To avoid code duplication, move strsep.c to the kernel/userland
common files.
Soon I will commit source-address selection (options IPSELSRC).
It will use strsep(3).
XXX: We still install rmd160.h and sha2.h in /usr/include/crypto, unlike
the other hash functions which get installed in /usr/include for compatibility.
inserted or removed. Refactor node insertion to not require rebalancing
all the time or a loop if it does. In rb_tree_swap_prune_and_rebalance,
don't call rb_tree_reparent_nodes, instead do the work ourselves (since
we will eventually undo half of the work of rb_tree_reparent_nodes).
functions to a separate rb_tree_ops structure. Make every int explicit
in being signed or unsigned. Use RBDEBUG to enable debug code. Move
rbt_count to RBSTATS. Use RBSMALL to not keep track of min/max.
macros, __BIT, __BITS, SHIFTIN, SHIFTOUT, and __arraycount() from
lib/libkern/libkern.h to sys/cdefs.h. Add a __-prefix to SHIFTIN
and SHIFTOUT, and add a manual page for the bit-twiddling macros,
bits(3).
Make the __BIT and __BITS macros "widthless," as best I can, by
changing their type to uintmax_t from uint32_t. XXX The manual
page lags this change by a bit.
Define __PRIxBIT and __PRIxBITS printf(3) format strings.
- struct timeval time is gone
time.tv_sec -> time_second
- struct timeval mono_time is gone
mono_time.tv_sec -> time_uptime
- access to time via
{get,}{micro,nano,bin}time()
get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)

along with my own additions.

FROMBCD()/TOBCD() macros into wrappers around it, resulting in both
smaller code footprint and elimination of possible issues due to
multiple evaluation of macro arguments.
