- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Forgot to commit these files too :-(

Minor clean up to shave about 1.5k off the size of the driver:
o remove unused fields from softc and args from cs_alloc_irq
o remove some commented code that will never be implemented.
o Don't try to send a packet and see if it worked. We don't
need this anymore, and it doesn't add any value.
o tweaks for BNC and AUI.
o limit possible time hung in the kernel to 4s rather than 40s.

cs has detach, remove bogus ifdef.
Remove dedundant initialization of error to 0.

Remove unused fields in softc. If they are ever really needed again,
they can re-added. Remove CS_NAME. Don't whine when there's an
ignored checksum error: User has said STFU, so we should S the FU.
(remove mandated properties).

Make the cs(4) driver MPSAFE:
- Add a mutex to the softc to protect the softc and the device hardware.
- Add a private timer to manage transmit watchdogs rather than using
if_timer/if_watchdog.
- Setup the interrupt handler after ether_ifattach().

Tested by: imp

o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

Use __FBSDID().
Also some minor style cleanups.

- Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)

Additional enhancments to allow IBM Etherjet cards to be probed,
attached and ifconfigable. The card doesn't interrupt yet.

Also, move towards bus space by introducing new macros/inline
functions which make such a move much easier than before.

These inline functions are setup now to work around an IBM EtherJet
pccard cardbus bridge incompatibility. The card works in 8 bit mode,
but not in 16-bit mode when it is connected to a cardbus bridge for
reasons unknown. The Linux driver also has a similar workaround in
it.

Future work will include making the above workaround runtime
conditional rather than compile time conditional, as well as fixing
the interrupts in pccards and converting it to bus space.

Break the isa attachment of the Crystal Semiconductor 89x0 into two
parts: isa and pccard. The isa one is known to work with an IBM
EtherJet ISA card. The pccard one isn't known to work because the
EtherJet pccard I purchased recently arrived DOA :-(. I'll commit the
pccard.conf entry when the replacement card arrives.

I plan on MFC this in a week or two.
