During the review of 09cdf4878c621be4cd229fa88cdccdcdc8c101f7 we
switched from cached registers to reading them as needed.
One read of the two reads was moved after the softreset got triggered
and as a result returned 0 rather than the proper register value.
Moving the read before the softreset gets initiated seems to make
things work again and xhci.c no longer complains about
"Controller does not support 4K page size.".

o Retire SS_FDREF as it is basically a debug flag on top of already
existing soref()/sorele().
o Convert SS_PROTOREF into soref()/sorele().
o Change reference model for the listen queues, see below.
o Make sofree() private. The correct KPI to use is only sorele().
o Make soabort() respect the model and sorele() instead of sofree().
Note on listening queues. Until now the sockets on a queue had zero
reference count. And the reference were given only upon accept(2). The
assumption was that there is no way to see the queued socket from anywhere
except its head. This is not true, since queued sockets already have pcbs,
which are linked at least into the global pcb lists. With this change we
put the reference right in the sonewconn() and on accept(2) path we just
hand the existing reference to the file descriptor.

Rename SS_NOFDREF to SS_FDREF and flip all bitwise operations.
Mark sockets created by socreate() with SS_FDREF.
This change is mostly illustrative. With it we see that SS_FDREF
is a debugging flag, since:
* socreate() takes a reference with soref().
* on accept path solisten_dequeue() takes a reference
with soref() and then soaccept() sets SS_FDREF.
* soclose() checks SS_FDREF, removes it and does sorele().

Change parts of RB_INSERT_COLOR and RB_REMOVE_COLOR to reduce the
number of operations, by, in some cases, flipping two color bits at a
time instead of flipping each individually, in separate operations,
and by using a switch statement to replace a sequence of if-elses.
Rewrite RB_SET_PARENT to generate fewer instructions. These changes
reduce the code size by over 100 bytes on some architectures.
Also, allow RB users to define a preprocessor symbol to generate
RB_REMOVE_COLOR code that matches the implementation described in the
original weak-AVL paper in one particular case, instead of the still
correct, but slightly more efficient implementation of that case
currently implemented.

pmcstat has been broken for analyzing logs since D35342 / b6e28991bf3aadb.
This is because the pmc for the first CPU is not added when reading logs
because unlike its clones, its event id is not invalid. That causes us
to fail the assertion at lib/libpmcstat/libpmcstat_logging.c:293

A broadly similar bug was discussed on Red Hat's bugzilla affecting

This suggests that as IEs were added to the 802.11 protocol the old code
was increasingly inadaquate to handle the additional IEs, not only a
