an item may be queued and processed later. While this is OK for mbufs,
this is a problem for control messages.
In the framework:
- Add optional callback function pointer to an item. When item gets
applied the callback is executed from ng_apply_item().
- Add new flag NG_PROGRESS. If this flag is supplied, then return
EINPROGRESS instead of 0 in case if item failed to deliver
synchronously and was queued.
- Honor NG_PROGRESS in ng_snd_item().
In ng_socket:
- When userland sends control message add callback to the item.
- If ng_snd_item() returns EINPROGRESS, then sleep.

Using ISO-10646-UCS-2 will cause a problem when we use our own

Little Endian with BOM

Big Endian
- NetBSD/i386 1.6 iconv

this needs to specify network byte order: the standard
does not specify (it is a 16-bit integer space)
Alias: csUnicode
- MSDN
Little Endian

Now using UTF-16BE is harmless, because
- same as UCS-2 with 2 byte range (U+0000 - U+FFFF)
- kernel code of each file systems(cd9660, msdosfs, ntfs) believes
Unicode is a 2 byte character at this time.
- UDF has only 2 byte range of Unicode filenames.
- It's defined at RFC2781.
So I believe it's time to change before starting new RELENG_6. :)

pointer doesn't point to the first instruction of that function, but
rather to a descriptor. The descriptor has the address of the first
instruction, as well as the value of the global pointer. The symbol
table doesn't know anything about descriptors, so if you lookup the
name of a function you get the address of the first instruction. The
cast from the address, which is the result of the symbol lookup, to a
function pointer as is done in db_fncall is therefore invalid.
Abstract this detail behind the DB_CALL macro. By default DB_CALL is
defined as db_fncall_generic, which yields the old behaviour. On ia64
the macro is defined as db_fncall_ia64, in which a descriptor is
constructed to yield a valid function pointer.
While here, introduce DB_MAXARGS. DB_MAXARGS replaces the existing
(local) MAXARGS. The DB_MAXARGS macro can be defined by platforms to
create a convenient maximum. By default this will be the legacy 10.
On ia64 we define this macro to be 8, for 8 is the maximum number of
arguments that can be passed in registers. This avoids having to
implement spilling of arguments on the memory stack.

This commit has:
- Removed the option from conf/options.*
- Removed the option and comments from MD NOTES files
- Simplified the CPU_ENABLE_SSE ifdef's so they don't
deal with CPU_ENABLE_SSE from kernel configuration. (*)
For most users, this commit should be largely no-op. If you used to
place CPU_ENABLE_SSE into your kernel configuration for some reason,
it is time to remove it.
(*) The ifdef's of CPU_ENABLE_SSE are not removed at this point, since
we need to change it to !defined(CPU_DISABLE_SSE) && defined(I686_CPU),
not just !defined(CPU_DISABLE_SSE), if we really want to do so.

by amd64 and i386: For buffered writes we collect data and write it
out a ${DEV_BSIZE}-sized block at a time. The fragsz variable is used
to keep track of how much data we have collected in the buffer so far
and it's reset to zero immediately after writing a block to the dump
device.
When the last, possibly partially filled buffer is flushed, we didn't
reset fragsz to 0 and as such would stop reflecting reality. Since we
currently only need to do buffered writes once, this isn't a problem.
However, when kernel dumps are made by hand (say by callling doadump
from within DDB), the improperly cleared state from the first call to
dumpsys causes the next call to dumpsys to create an invalid code file.
This change resets fragsz after flushing the partially filled buffer so
that it fixes the two problems at once.

o Grab the MAC address out of the CIS if the card has the special
3Com 0x88 tuple. Most 3Com cards don't have this tuple, but we
prefer it to the eeprom since it only appears to be present when
the eeprom doesn't have the info. So far, I've only observed this
on my 3C362 and 3C362B cards, but the NetBSD driver implies that
the 3C362C also has this tuple, and that some 3C574 cards do too (none
of mine do). ep_pccard_mac was written after looking at the NetBSD

cases.
CARD_SCAN_CIS(device_get_parent(dev), function, argp)
scans the CIS of the card, passing each tuple to function with
the tuple and argp as its arguments. Returning 0 continues the scan,
while returning 1 terminates the scan. The value of the last
invocation of function is returned from this function.
