proved to be necessary to make the static drivers work
in EITHER/OR or BOTH configurations. Modules will still
build in sys/modules/igb or em as before.
This also updates the igb driver for support for the 82576
adapter, adds shared code fixes, and etc....

- Coverity Prevent(tm) CID 1906 a bogus use of bzero where unneeded.
- ICH8 systems autoneg to 100 rather than 1000, this can also be
seen in 82573, the logic was backwards.
- On new 82575 quadports half duplex tx speed is slow... this was due
to overwriting TCTL reg rather than adding bits.

shared code infrastructure that is family specific and
modular. There is also support for our latest gigabit
nic, the 82575 that is MSI/X and multiqueue capable.
The new shared code changes some interfaces to the core
code but testing at Intel has been going on for months,
it is fairly stable.
I have attempted to be careful in retaining any fixes that
CURRENT had and we did not, I apologize in advance if any
thing gets clobbered, I'm sure I'll hear about it :)

80003 NICs and NICs found on ICH8 mobos, and improves support for
already known chips.
Details:
- if_em.c. Merged manually, viewing diff between new vendor
driver and previous one. This was an easy task, because
most changes between 5.1.5 and 6.0.5 are bugfixes taken
from FreeBSD.
- if_em_hw.h. Dropped in from vendor, and then restored
revisions 1.16, 1.17, 1.18.
- if_em_hw.c. Dropped in from vendor, and then restored
revision 1.15.
- if_em_osdep.h. Added new required macros from vendor file
and add a hack against define namespace mangling in
if_em_hw.h. Intel made another hack, but I prefer mine.

new chips and improves support for already supported ones.
Some details, important for future merges:
- if_em.c merged manually, viewing diff between new vendor
driver and previous one.
- if_em_hw.h dropped in from vendor, and then restored revisions
1.16, 1.17, 1.18.
- if_em_hw.c dropped in from vendor, and then two liner change made,
that restores support for two rare chips.
