setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.
Convert all calls to POSIX from historic BSD API:
- unsetenv returns an int.
- putenv takes a char * instead of const char *.
- putenv no longer makes a copy of the input string.
- errno is set appropriately for POSIX. Exceptions involve bad environ
variable and internal initialization code. These both set errno to
EFAULT.
Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit. A few I re-wrote to use setenv()
instead of putenv().
New regression module for tools/regression/environ to test these
functions. It also can be used to test the performance.

"static". The header file generated by "rpcgen -h" will always declare
it as extern, leading to a "static after extern" error being issued by
gcc-4.2. This caused only a warning in gcc-3.x, but it has been wrong
all the time.
This change does not modify the code generated by "rpcgen -m", it only
affects rpcgen used to generate server stubs with a local main function.
This is the minimal patch. It does not remove the now obsolete "storage"
parameter from write_program() and write_programs() in an attempt to keep
differences to other systems' versions of rpcgen as small as possible.
priorities, etc.) in the NICE field:
Use a combination of pri_native and pri_user instead of pri_level to
guess the original realtime priority. Using pri_level here has been
wrong since 2001/02/12. Using only pri_native here would be correct
if the kernel actually initialized it reasonably. (The kernel exports
its raw td_base_priority as pri_native, but userland mostly wants a
refined base priority). Give up on waiting pri_native to work correctly
and only use it when there is nothing better (for kthreads).
This should reduce printing of bizarre pseudo-nice values. Bizarre
values are still printed if we observe a transient borrowed priority
for a kthread (transient borrowing is the main thing that makes the
raw td_base_priority almost useless in userland), or if there is a
kernel bug. One current kernel bug involves the kernel idprio thread
pagezero permanently changing its priority from PRI_MAX_IDLE (255) to
PUSER (160). Then the bizarre value "ki-6" is printed instead of
"ki31". Here "-6" is PRI_MIN_IDLE - PUSER = -64 truncated to 2
characters. We are observing a transient borrowed priority that has
become permanent due to a bug.
ps/print.c:priorityr() needs similar changes (including ones in stage 2
here).

and protocol-independent host mode multicast. The code is written to
accomodate IPv6, IGMPv3 and MLDv2 with only a little additional work.
This change only pertains to FreeBSD's use as a multicast end-station and
does not concern multicast routing; for an IGMPv3/MLDv2 router
implementation, consider the XORP project.
The work is based on Wilbert de Graaf's IGMPv3 code drop for FreeBSD 4.6,
which is available at: http://www.kloosterhof.com/wilbert/igmpv3.html
Summary
* IPv4 multicast socket processing is now moved out of ip_output.c
into a new module, in_mcast.c.
* The in_mcast.c module implements the IPv4 legacy any-source API in
terms of the protocol-independent source-specific API.
* Source filters are lazy allocated as the common case does not use them.
They are part of per inpcb state and are covered by the inpcb lock.
* struct ip_mreqn is now supported to allow applications to specify
multicast joins by interface index in the legacy IPv4 any-source API.
* In UDP, an incoming multicast datagram only requires that the source
port matches the 4-tuple if the socket was already bound by source port.
An unbound socket SHOULD be able to receive multicasts sent from an
ephemeral source port.
* The UDP socket multicast filter mode defaults to exclusive, that is,
sources present in the per-socket list will be blocked from delivery.
* The RFC 3678 userland functions have been added to libc: setsourcefilter,
getsourcefilter, setipv4sourcefilter, getipv4sourcefilter.
* Definitions for IGMPv3 are merged but not yet used.
* struct sockaddr_storage is now referenced from <netinet/in.h>. It
is therefore defined there if not already declared in the same way
as for the C99 types.
* The RFC 1724 hack (specify 0.0.0.0/8 addresses to IP_MULTICAST_IF
which are then interpreted as interface indexes) is now deprecated.
* A patch for the Rhyolite.com routed in the FreeBSD base system
is available in the -net archives. This only affects individuals
running RIPv1 or RIPv2 via point-to-point and/or unnumbered interfaces.
* Make IPv6 detach path similar to IPv4's in code flow; functionally same.
* Bump __FreeBSD_version to 700048; see UPDATING.
