c47476d7e6 Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().
Most calls to bus_alloc_resource() use "anywhere" as the range, with a given
count.  Migrate these to use the new bus_alloc_resource_anywhere() API.

2dd1bdf183 Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

f6cea53f9d Create a generic PCCARD_PNP_INFO from the MODULE_PNP_INFO building
block. Use it in all the PNP drivers to export either the current PNP
table. For uart, create a custom table and export it using
MODULE_PNP_INFO since it's the only one that matches on function
number.

2a8c860fe3 In order to reduce use of M_EXT outside of the mbuf allocator and
socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

9f9b77e713 Add locking to snc(4) so it is MPSAFE:
- Add a mutex to the softc to protect the softc and device hardware.
- Use a private timer routine to drive the transmit watchdog timer instead
  of using if_watchdog/if_timer.
- If if_alloc() fails during attach, fail the attach with an error rather
  than panic'ing.
- Clear RUNNING and OACTIVE only in sncstop().
- Don't mess with IFF_UP.
- Don't leak 'struct ifnet' on detach.
- Setup interrupt handler after ether_ifattach().
- Call ether_ifdetach() rather than if_detach() in the pccard detach
  routine.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

fbfb97942e It turns out that the module dependency on pccard is in error. Since
there's not dependencies on pccard symboles, such a dependency is not
necessary.  This means that drivers that have multiple attachments can
not drag bogus devices into the kernel at load time.

We can't (yet) do this with pci and isa.  Drivers written for them
actually do seem to have symbols that depend on these busses'
implementation code.

ndis not touched until other things can be tested.
