non-blocking BIOs so that it is sane -- so that, in other words, -1 with
a meaningful library error code (WANT_READ or WANT_WRITE) is returned
when we would block for I/O. Without this change, you have to sleep or
spin -- you can't know how to put the underlying socket in your select
or poll set.
Patch from http://marc.info/?l=openssl-dev&m=115154030723033&w=2 and
rationale at http://marc.info/?l=openssl-dev&m=115153998821797&w=2 where
sadly they were overlooked by the OpenSSL team for some time. It is hoped
that now that we've brought this change to their attention they will
integrate it into their sources and we can lose the local change in
NetBSD.
The rule is, if you change scan.l or gram.y, you bump the config(5)
version. If you implement the changes under sys/conf/files or affiliate,
you bump the required version in sys/conf/files or in an appropriate place
to minimise annoyance. If the changes makes new config(1) incompatible
with a previous version of config(5), embed it in config(1) using the
CONFIG_MINVERSION definition along with CONFIG_VERSION.
This has been in the tree for what, 3 years now? It's even documented...
ones, mostly network pseudo interfaces) and those which use autoconf
to attach instances dynamically, or to attach child devices.
Use a new keyword "defpseudodev" for the latter.
Issue a warning if interface attributes are used with "old" pseudodevs,
but let it work as before for now. This will be removed soon.

reorganized MI i2c_bitbang.c:
- set GPOER register in set_dir function too according to GPOUTR value
- in set_bits function, don't set SDA_BIT implicitly in input mode and
check current direction to handle GPOER register
- no need to check direction in read_check function because reading SCL
is valid even if SDA is output

o agp_ali.c: remove unused 'agp' member from agp_ali_softc.
o drm: agp_find_device() returns 'void *', not a device_t.
o Use device_t, cfdata_t instead of struct pointers.
o Don't cast void pointers in assignments.

registers in DDB. Names with initial "s" (for "saved") are somewhat
confusing to use. The fact that we use SPC/SSR registers to retrieve
values of PC/SR at the moment of trap is an immaterial implementation
detail.
