on descriptors, this can be achieved thanks to the new getdtablecount()
system call. application may provide a reserve count to ensure that the
recvmsg() call is not called when they don't have enough descriptors to
work properly.
change the API so that transient errors that can be retried immediately
are retried within the function right away, whereas transient errors for
which the application may want to take action will set errno to EAGAIN.

effective result.  its use is NOT discouraged -- it is not
common, but when you need it, there is nothing else that will do.

explaining of "what a C string is", and make it more clear that these
functiosn BEHAVE EXACTLY LIKE snprintf with "%s"!  (anyone who wants
to write a 'strlcpy considered harmful' paper should probably write a
'strlcpy and snprintf considered harmful' paper instead).

be very good if this new manual was picked up in your project.

specifically, rewrite them to permit some markup in the column headers,
and use "Ta" instead of literal tabs; mandoc does not currently match groff
100%, but a mandoc fix may be some time off, and we've gone enough releases
with poorly formatting column lists.
in some cases i have rewritten the lists as -tag, where -column made
little sense.

.Bl -column header1 header2 ... <Bl flags>
mixing things up confuses mandoc, and adding flags in can screw up the list.
this hopefully just makes things a bit safer (and more consistent).
(one more bit of work left and all column lists should format how we want)
