Split out the ISA bus front end code into its own file. PCCARD attachment coming later this week. Mitsuru IWASAKI provided a patch to -mobile which I used to make sure I was doing the right thing but only a small part of the actual patch was used.

sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

struct ex_softc {
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.

Some PC Card variants of the 82365 don't seem to like setting the IRQ number in the irq register. While there are other issues with these variants, avoiding writing to it helps interrupt generation on at least one card, and doesn't hurt on the others. Flag ISA attachment as needing INT_NO_REG written, and don't update the PC Card attachment (which will have the effect of not touching it for PC Cards). Document this in a comment, and tweak one or two formatting nits while I'm here.
