In sockopt_alloc(), 'sopt' may already have been initialized with
'sopt->sopt_data = sopt->sopt_buf'. If the allocation fails, we
end up with 'sopt->sopt_data = NULL', and later try to free this
NULL pointer in sockopt_destroy().
Fix that by not modifying 'sopt_data' if the allocation failed.
Difficult to reproduce in normal times, but fault(4) makes it
easy.

==> Provide a much more complete set of setters and getters for different
value types in the prop_array_util(3) and prop_dictionary_util(3)
functions.
==> Overhaul the prop_data(3), prop_number(3), and prop_string(3) APIs
to be easier to use and less awkwardly named, Deprecate the old
awkward names, and produce link-time warnings when they are referenced.
==> Deprecate mutable prop_data(3) and prop_string(3) objects. The old
APIs that support them still exist, but will now produce link-time
warnings when used.
==> When the new prop_string(3) API is used, strings are internally
de-duplicated as a memory footprint optimization.
==> Provide a rich set of bounds-checked gettter functions in and a
corresponding set of convenience setters in the prop_number(3) API.
==> Add a new prop_bool_value(3) function that is equivalent to
prop_bool_true(3), but aligned with the new "value" routines in
prop_data(3), prop_string(3), and prop_number(3).
WRITE_REGION_1 command for writing blocks of data to the device.
This is to address a performance issue where "ifconfig run0 up" would
take as long as 20-30 seconds when using a UHCI or OHCI host
controller due to the large number of control transfers performed by
the driver in combination with the inability of those host controllers
to perform multiple control transfers per USB frame. Limit the
transfers to 64 bytes as in the corresponding #if'ed-out code in
FreeBSD. Currently only enabled for mac_ver 0x5390 as it is the only
version tested so far.
- remove unused LM slots
- use #defines for defining the size of CVMSEG LM users
XXX: Need to dynamically set CVMMEMCTL[LMEMSZ] during startup so we can
both adapt to any future increase in CVMSEG LM usage and not waste
any more L2 that we need to.
XXX: Still need to move general IOBDMA conf to a different (new?) header.
u3g_attach() with the interface already passed in uiaa->uiaa_iface and
store the interface in sc->sc_iface for later use by u3g_open()/
Also skip Direct IP interfaces in u3g_match() to avoid potential side effects.
