just stop updating fts_level so we don't overflow it.  This allows
rm, find, etc to operate on very deep hierarchies.  Consumers of
fts(3) do need to be aware that the actual level may be larger
than fts_level.  During the next libc major bump we will make
fts_level an int instead of a short.  OK deraadt@

attempts to "ifconfig carp down" noticed by david@.
- use non-descriptive variables names rather than $if/$junk to encourage
people reading the code to think what it's doing; many of the output lines
are not interface names.

formats.  which even for 80-bit & 128-bit long doubles is only 15
bits.  therefore, scalbln, scalblnf, scalblnl are essentially the
same as scalbn, scalbnf, scalbnl with bounds checking so that
LONG_MIN..INT_MIN, and INT_MAX..LONG_MAX ranges properly raise
exceptions & yield correct values.  looks good to millert@

cannot cooperate with other programs.  The aim of this change is
to allow any program to send midi data to other programs as they
were midi hardware. For instance, this change should solve the
longstanding problem of using a midi sequencer with software
synthesizers. More precisely:
- new midicat(1) utility (actually hardlink to aucat(1)).
it creates software midi thru boxes, allowing programs
to send midi messages to other programs as they were
midi(4) hardware.
- new midi api in libsndio (see mio_open(3)), to access
midi(4) devices and midicat(1) sockets in a uniform way.
- new device naming scheme <service>:<unit>[.<option>],
common to audio and midi.
- new sndio(7) manual describing concepts and naming
The current audio device naming still works, but people having
scripts or configuration files containing device names could read
the sndio(7) man page and slowly start updating device names.

ok otto millert

Make the imsg protocol network-safe.
it might be network safe, but half the imsg based daemons on my firewalls
dont run anymore.

Currently the receiver fetches an imsg via imsg_get() and if he expects
an fd, he then calls imsg_get_fd() to fetch the next fd queued on the
imsgbuf from which the imsg came.
This changes hides the fd queueing mechanism to the API user.  When closing
an imsg with an fd, the message is flagged so that the receiving end knows
it must dequeue the fd in imsg_get() and return it with the imsg structure.
This way there is no (less) possible screw up from imsg_get_fd() not being
called directly after imsg_get() by the user. The retreived imsg is
self-contained.
