MFC 306564: Expose kernel-only errno values if _WANT_KERNEL_ERRNO is defined.
The kernel uses a few negative errno values for internal conditions
such as requesting a system call restart. Normally these errno values
are not exposed to userland. However, kdump needs access to these
values as some of then can be present in a ktrace system call return
record. Previously kdump was defining _KERNEL to gain access to ehse
values, but was then having to manually declare 'errno' (and doing it
incorrectly). Now, kdump uses _WANT_KERNEL_ERRNO instead of _KERNEL
and uses the system-provided declaration of errno.

MFC 306562: Handle 64-bit system call arguments (off_t, id_t).
In particular, 64-bit system call arguments use up two register_t
arguments for 32-bit processes. They must also be aligned on a 64-bit
boundary on 32-bit powerpc processes. This fixes the decoding of
lseek(), procctl(), and wait6() arguments for 32-bit processes (both
native and via freebsd32).
Note that the ktrace system call return record only returns a single
register, so the return value of lseek is always truncated to the low
32-bits for 32-bit processes.

sfxge(4): fix efx_filter_supported_filters API
The previous API had various problems, including the length of the
caller provided buffer not being specified, no means being available
to discover how big the buffer needs to be, and a lack of clarity of
what the resulting list contains.
To fix it:
- add the buffer length as a parameter
- if the provided buffer is too short, fail with ENOSPC and return the
required length
- ensure that the list contents are valid and add comments
describing it
It is safe to change this API as, unsuprisingly, it has no users.

sfxge(4): split EFX_FILTER_MATCH_LOC_MAC_IG back into separate flags
The flag EFX_FILTER_MATCH_LOC_MAC_IG to represent filtering on the
individual/group bit of the MAC address (with the two cases being
distingusished by the MAC address in the filter specification) was
introduced to mirror the Linux driver filtering code, but the
implementations are different enough anyway that it isn't of much value.
Having separate flags for unknown unicast and multicast simplifies
the code and allows the set of flags to match those used by MCDI.
It will also makes it easier to report whether these filters are
supported.
In the MCDI definitions, the unknown multicast and unicast flags have
the values 0x40000000 and 0x80000000 respectively, and so using the
same values for simplicity requires 32 bits in the filter specification
to store the flags. This means the structure is now a little bigger
than 64 bytes, but filters are not often used on critical paths so this
shouldn't have much impact - on Linux they are also bigger than they
used to be.
