introduce two new APIs for requesting strong random numbers:
arc4random_buf() - fill an arbitrary memory range with random numbers
arc4random_uniform() - return a uniformly distributed random number
below
a specified upper bound, avoiding the bias that comes from a naive
"arc4random() % upper_bound" construction.
these mirror similarly-named functions in the kernel;
lots of discussion deraadt@ mcbride@
should be good, plus it prevents weird things from happening if
len > INT_MAX.
- Since n is now size_t, compare it against 0 instead of >= 0.
- temp is used to store individual bytes, so use char instead
(matches fp and tp).
- millert noted that the comma operator may not guarantee order of
execution, so replace with semicolons.
Found by lint, OK millert.
bootblocks have been moved, but we want 4.2 to be upgradeable. So
reduce the footprint of the bsd.rd by shrinking the ramdisk filesystem
because it is way too large. tested by sthen and kettenis
- rdr-anchor "relayd/*": the anchor used by relayd to load
redirections into pf.
- pass in on $ext_if proto icmp to ($ext_if): it is a bad habit to
block icmp, this example proposes to allow it by default.

This allows recovery after an IP address change (e.g. on dialup links).
Also move the update of "nextaction" timeout below the deadline check.

has been loaded. Otherwise, states that are received during the
initial bulk update mismatch the correct pf-checksum and
do not attach to the rules.
Problem identified by david@. Fix done in collaboration.

make the installation media's life easier:
- stop using ``Pc'' as a getty terminal type, use std.9600 instead.
- on platforms with multiple virtual consoles (alpha, amd64, i386,
zaurus), console is disabled, various ttyC* are enabled.
- on other platforms, console is enabled, all other devices are
disabled. This only changes armish, mac68k, sgi.
- default terminal for console is unknown on serial-only machines, vt220
on glass-capable machines (questionable, but done for consistency).
- minor whitespace changes.
- glass console forgotten on a couple platforms (luna88k, sparc64, vax).
eyeballed by deraadt@, ok krw@
instead of the generic pthread macros since free(3) uses __arc4_getbyte()
when freeing small sized allocations and the generic pthread macros call
malloc(3).
- eliminate passing pointers to a static variable with global scope (rs)
for additional code clarity and reduction.
- shlib minor bumps for libc and libpthread due to new functions.
From andreas@ with some bits from me. okay tedu@ marc@ w/some spot

because otherwise the poll timeout will stay at SETTIME_TIMEOUT (15s)
forever unless we time out waiting for the first reply with -s

replace IPv4 and IPv6 loopback zones with BIND's autogenerated empty zones.
move root.hint to /var/named/etc
remove empty directory /var/named/standard
and graphical console based on the selection made in the ARCBIOS.
Early attachment of gbe(4) is still required, otherwise we have a working
graphical console.
