Fix atmconfig compilation when MK_ATM == yes and MK_BSNMP == no

Makefile.inc1:
Always compile gensnmptree with bootstrap-tools when MK_BSNMP != no
instead of depending on a potentially stale tool installed on the build host

sbin/atm/atmconfig/Makefile:
- Always remove oid.h to avoid cluttering up the build/src tree.
- Consolidate all of the RESCUE/MK_BSNMP != no logic under one
conditional to improve readability
- Remove unnecessary ${.OBJDIR} prefixing for oid.h and use ${.TARGET} instead
  of spelling out oid.h
- Add a missing DPADD for ${LIBCRYPTO} when compiled MK_BSNMP == yes and
  MK_OPENSSL == yes and not compiling for /rescue/rescue

sbin/atm/atmconfig/main.c:
Change #ifndef RESCUE to #ifdef WITH_BSNMP in main.c to make it
clear that we're compiling bsnmp support into atmconfig

sh: Mask off shift distance (<< and >>) in arithmetic.

In C, shift distances equal to or larger than the number of bits in the
operand result in undefined behaviour. As part of eliminating undefined
behaviour in arithmetic, mask off the distance like Java and JavaScript
specify and C on x86 usually does.

Assumption: conversion from unsigned to signed retains the two's complement
bits.
Assumption: uintmax_t has no padding bits.

net: move interface removal notification up in if_detach_internal

This is needed to prevent having interfaces with ifp->if_addr == NULL
on bridge interfaces. Moving the notification event handlers up makes
sure the interfaces are removed before doing any more cleanup.

Use mount protocol version 3 by default for showmount and umount.
mount_nfs effectively uses mount protocol v3 by default already.
v1 mount protocol is being removed along with nfsv2 by a high profile NFS
appliance vendor and our legacy v1 mount protocol usage causes rpc errors.
Update to the current version of netmap.
Mostly bugfixes or features developed in the past 6 months,
so this is a 10.1 candidate.

Basically no user API changes (some bugfixes in sys/net/netmap_user.h).

In detail:

1. netmap support for virtio-net, including in netmap mode.
  Under bhyve and with a netmap backend [2] we reach over 1Mpps
  with standard APIs (e.g. libpcap), and 5-8 Mpps in netmap mode.

2. (kernel) add support for multiple memory allocators, so we can
  better partition physical and virtual interfaces giving access
  to separate users. The most visible effect is one additional
  argument to the various kernel functions to compute buffer
  addresses. All netmap-supported drivers are affected, but changes
  are mechanical and trivial

3. (kernel) simplify the prototype for *txsync() and *rxsync()
  driver methods. All netmap drivers affected, changes mostly mechanical.

4. add support for netmap-monitor ports. Think of it as a mirroring
  port on a physical switch: a netmap monitor port replicates traffic
  present on the main port. Restrictions apply. Drive carefully.

5. if_lem.c: support for various paravirtualization features,
  experimental and disabled by default.
  Most of these are described in our ANCS'13 paper [1].
  Paravirtualized support in netmap mode is new, and beats the
  numbers in the paper by a large factor (under qemu-kvm,
  we measured gues-host throughput up to 10-12 Mpps).

A lot of refactoring and additional documentation in the files
in sys/dev/netmap, but apart from #2 and #3 above, almost nothing
of this stuff is visible to other kernel parts.

Example programs in tools/tools/netmap have been updated with bugfixes
and to support more of the existing features.

This is meant to go into 10.1 so we plan an MFC before the Aug.22 deadline.

A lot of this code has been contributed by my colleagues at UNIPI,
including Giuseppe Lettieri, Vincenzo Maffione, Stefano Garzarella.

Move the imx6 sysctl temperature info to hw.imx6 where all the other
soc-wide info lives.  It was under dev.imx6_anatop.0.

What does anatop mean anyway?  Nobody seems to know, so it's probably
not where somebody will think to look for imx6 hardware info.
Factor out the common code for function boundary tracing instead of
