This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a.  This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes.  'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

consequently move all tables in the examples to the beginning and before the

On a real mailserver, it's too noisy and may be a privacy concern.
On a machine that's not a mailserver, it's pointless.
Besides, Theo points out that running subsystems that potentially
parse untrusted user data daily, at a predictable time, as root
is not a very good idea in the first place.

unused for now, but I plan to convert all programs in base to use it in
a future diff. /dev/bpf0 is for compatibility with existing binaries
and is to be removed after a transition period.

chance to update the *default* configuration of the important daemons.
Factorize rc.firsttime into a run_upgrade_script() function which takes the
script suffix name as an argument.

It works by adding daemon_rtable=$id in /etc/rc.conf.local.
rcctl(8) support coming in a few and so are the man pages bits.
If you want multiple instances of the same daemon running in different
routing tables, just symlink the original rc.d script.
e.g.
# cd /etc/rc.d && ln -s dhcpd dhcpd42
Then enable your daemons as such in rc.conf.local:
dhcpd_flags=
dhcpd42_flags=
dhcpd42_rtable=42
most work done by Jiri B <jirib@devio.us>; with a few tweaks and simplifications
by yours truly

... should make henning happy ;-)

daemon_class, daemon_flags, daemon_timeout, daemon_user, pexp
Add "pexp" as a valid variable to _rc_parse_conf() and sort the list while here.
Besides having an easy way to see how a daemon was started exactly, it opens the
door to rdomain/rtable support in rc.d(8). We need to have as much information
on a daemon as possible if we want to target a specific rtable (using -T) and it
also makes it easier to start multiple instances of the same daemon with similar
flags as a different user...
Of course that only works with rc.d scripts *not* overwritting the default rc_*
functions.
Man page tweaks coming later.

The getenv(3) and unsetenv(3) functions already support this.
This will make it easier to emulate the glibc clearenv() function in ports.

CUPS wants it to be a symlink, and that is probably the most common
printing system.  Bad idea to constantly spam everybody about that!

authors need only to ensure there is an entry in NAME for any function/

removing its second parameter and the enum() that provided the
values for said parameter.
The function was only called with the second parameter set to one
value (BM_NONBLOCKING) from the enum(). So just do the right thing.
Similar to changes made in smtpd.
While here remove the pointless third parameter from the fcntl(F_GETFL)
call.
