This has reduced the number of TX delimiter and data underruns when
doing large UDP transfers (>100mbit).
This stops any HAL_INT_TXURN interrupts from occuring, which is a good
sign!

* Delete this debugging print - I used it when debugging the initial
TX descriptor chaining code. It now works, so let's toss it.
It just confuses people if they enable TX descriptor debugging as they
get two slightly different versions of the same descriptor.

part of ts_status. Thus:
* make sure we decode them from ts_flags, rather than ts_status;
* make sure we decode them regardless of whether there's an error or not.
This correctly exposes descriptor configuration errors, TX delimiter
underruns and TX data underruns.
qsort(3) can work together to sort an array of integers.

If a stack mark is set while the current stack block is empty, the stack
block may move later on (because of realloc()) and the stack mark needs to
be updated. This updating does not happen after popstackmark() has been
called; therefore, call setstackmark() again if the stack mark is still
being used.
For some reason, this only affects a few users. I cannot reproduce it. The
situation seems quite rare as well because an empty stack block would
usually be freed (by popstackmark()) before execution reaches a
setstackmark() call.

OpenBSD's gcc is very different that it only helped w/ where to modify,
