universe output files. [1] Similarly make FAILFILE start with "_." as well.

maximum value instead of just truncating the most significant part
silently.
Could happen for example if the capacity of the device is more
than 2TB, so that the number of sectors is greater than 2Mib.

local symbols.

Because {NGROUPS_MAX} may become variable, its value should be obtained
using sysconf(3). If a #define is used anyway, it should be obtained by
including <limits.h> as that is in POSIX like getgroups(2) itself is.
<sys/param.h> is not in POSIX.

The v1 and v3 interfaces returned the whole EEPROM but the v14/v4k
interfaces just returned the base header. There's extra information
outside of that which would also be nice to get access to.
The rxmonitor hook is called on each received packet. This can get very,
very busy as the tx/rx/chanbusy registers are thus read each time a packet
is received.
Instead, shuffle out the true per-packet processing which is needed and move
the rest of the ANI processing into a periodic event which runs every 100ms
by default.
- The mean RTT is updated at the end of each congestion epoch, but if we switch
to congestion avoidance within the first epoch (e.g. if ssthresh was primed
from the hostcache), we'll trigger a divide by zero panic in
cubic_ack_received(). Set the mean to the min in cubic_record_rtt() if the
mean is less than the min to ensure we have a sane mean for use in this
situation. This fixes the panic reported by Nick Hibma.
- Adjust conditions under which we update the mean RTT in cubic_post_recovery()
to ensure a low latency path won't yield an RTT of less than 1. This avoids
another potential divide by zero panic when running CUBIC in networks with
sub-millisecond latencies.
- Remove the "safety" assignment of min into mean when we don't update the mean
because of failed conditions. The above change to the conditions for updating
the mean ensures the safety issue is addressed and I feel it is better to keep
our previous mean estimate around if we can't update than to revert to the
min.
- Initialise the mean RTT to 1 on connection startup to act as a safety belt if
a situation we haven't considered and addressed with the above changes were to
crop up in the wild.

hexdump.
This is a part replacement of the old athprom code, which tries
to both fetch and print the contents of an eeprom dump.
A tool to generate hexdumps from a running system will follow shortly.
* add missing includes to quieten warnings
* fix an inline function decl to have a return type
* since .h files are created during the build (opt_ah.h, ah_osdep.h)
which modify the behaviour of the HAL include/source files,
include OBJDIR in the path so the #include's work.
The tools should now build when the directory is added to LOCAL_DIRS
during a make buildworld.
