forcing all transfers to do the start read/write stop by hand. Some
smart bridges prefer this sort of operation, and this allows us to
support their features more easily. When bridges don't support it, we
fall back to using the old-style opertaions. Expand the ioctl
interface to expose this function. Unlike the old-style interface,
this interface is thread safe, even on old bridges.
Introduce framework to configure the multiplexed pins on boot.
Since the USART supprots RS-485 multidrop mode, it allows the
TX pins to float. However, for RS-232 operations, we don't
want these pins to float. Instead, they should be pulled up
to avoid mismatches. Linux does something similar when it
configures the TX lines. This implies that we also allow the
RX lines to float rather than be in the state they are left in
by the boot loader. Since they are input pins, I think that
this is the right thing to do.
Plus minor for our board.
in rev. 1.34. Mainly I missed the fact that the buffer is used for two
purposes:
1) storing a group line from the group file;
2) __gr_parse_entry() parses the buffer and tries to put the group
members to the remaining part of the buffer and can fail if there
is no enough room for them.
Re-arrange the buffer size checks to account the latter case.

protocol of a socket close event distinct from a detach event, which
will (in a future commit) become aligned with pru_abort, which will
also be a notification of close prior to detach. Add prurequests event
for close, as well as patch up some existing missing ones.
instead of maximum sized arrays embedded in the table structures and (2)
using pointers to constant oids instead of copying the oid into each
table structure. This also fixes indexing in the case when a string used
for indexing is longer than the maximum size allowed in the MIB.

Add MEMORY_BARRIER for the few scratch dma ops that were missing
them plus add a couple of hi 32 bit dma ops (we could probably
allow 64 bit scratch and request/response queue dma now).
instead of setup_nanobsd(), because this gives customize tasks a chance
to fiddle the details.

don't want to mix process and thread scheduling options together in these
functions, now the thread scheduling option is implemented in new thr
syscalls.
