- 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.

- Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9) etc
and take advantage of rman_get_rid(9) in order to save some softc
members.
- Provide and consume module dependency information for lebuffer(4).

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

Remove BUS_DMA_WAITOK from bus_dma_tag_create() invocations as it's
no valid flag there.

Use bus_get_dma_tag() to obtain the parent DMA tag so le(4) works on
platforms requiring this.

- Add C-bus and ISA front-ends for le(4) so it can actually replace
lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
network cards as lnc(4) did and additionally a couple of PNP ones.
Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
and is untested due to lack of such hardware, but given that's it's
based on the respective lnc(4) and not too different from the ISA
front-end it should be highly likely to work.
- Remove the descriptions of le(4), which where converted from lnc(4),
from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
one in sys/conf/NOTES.
