If unwinding stops due to hitting the end of the call chain, the return
value is supposed to be _URC_END_OF_STACK; other values indicate internal
errors. The return value from get_eit_entry() is now returned without
translating it to _URC_FAILURE, so that callers can see _URC_END_OF_STACK
when it happens.
When raising an exception, the unwinder searches for a catch handler and if
none is found it should invoke std::terminate() with the uncaught exception
as the "current" exception. Before this change, the terminate handler was
invoked with no exception as current (abi::__cxa_current_exception_type()
returned NULL), because the return value from the unwinder indicated an
internal failure in unwinding. It turns out that was because all errors
from get_eit_entry() were translated to _URC_FAILURE. Now the error is
returned untranslated, which allows _URC_END_OF_STACK to percolate upwards
to throw_exception() in libcxxrt. When it sees that return status it
properly calls std::terminate() with the uncaught exception installed
as the current exception, allowing custom terminate handlers to work
with it.
vm_page_try_to_free() is testing conditions, like clean versus dirty,
that only vary in managed pages.

nfsm_uiombuflist() zero filled the mbuf list to a multiple of 4bytes
as required for XDR. Unfortunately that modified an mbuf list after
it was m_copym()'d and was broken. This patch removes the zero filling code.
Since nfsm_uiombuflist() is not yet used in head/current, this has no
effect on users.
The function will be used by a future commit of code that adds Flex

paging queue. Nonetheless, passing PQ_INACTIVE to vm_page_unwire()
creates the appearance that the page "frame" is being enqueued in the
inactive queue. As of r288122, we can avoid this false impression by
passing PQ_NONE.

- Import print_function from __future__ and use print(..) instead of `print ..`.
- Use repr instead of backticks when the object needs to be dumped, unless
print(..) can do it lazily. Use str instead of backticks as appropriate
for simplification reasons.
This doesn't fully convert these modules over py3k. It just gets over some of

1) Choose correct Firmware options for HW LRO for best performance
2) Delete TBD and other comments which are not required.
3) Added sysctl interface to enable / disable / modify different factors
of HW LRO.
4) Disabled HW LRO by default to avoid issues with packet forwarding
This allows much better control over the LRO configuration via sysctls, and
uses much better defaults. Hardware LRO can now be enabled/disabled
independantly from the software LRO, and the tuning parameters are exposed.

Move TX out of the enqueue() path. As a result, we need
to have ifmp_ring_check_drainage() pick up from the abdicate state.
We also need to either enqueue the TX task, or check drainage
after calling ifmp_ring_enqueue() to ensure it's sent.
This change results in a 30% small packet forwarding improvement.
