busdma - Remove filter functionality
- Remove filtfunc and filtarg arguments from bus_dma_tag_create() and fix all callers. All callers use NULL today for both filterfunc and filterarg with one exception: if_jme.
- Remove filter functionality internally and parent tag tracking. Without filter functions, we do not need to keep track of tag ancestry. All inheritance of the parent tag's parameters occurs when creating the new child tag.
- rename run_filter() to addr_needs_bounce().
- FreeBSD keeps the filtfunc and filtarg arguments but requires them to be NULL.
- Drop filterfunc usage from if_jme.
In case of "JMC260 chip full mask revision 2", which has a hardware bug when it comes to DMA transfers crossing the 4 GB bounday, the parent buffer tag already limits DMA memory to 32bit address space. As such it should be safe to drop the filterfunc. The filterfunc was checking if the lower 32bits of the physical address used for DMA are all 0. In case of a 32bit address space, the only address where all lower 32-bits are all zero is 0 itself and I am here assuming that the physical address 0 is not used for DMA transfers!

kernel: Move us to using M_NOWAIT and M_WAITOK for mbuf functions.
The main reason is that our having to use the MB_WAIT and MB_DONTWAIT flags was a recurring issue when porting drivers from FreeBSD because it tended to get forgotten and the code would compile anyway with the wrong constants. And since MB_WAIT and MB_DONTWAIT ended up as ocflags for an objcache_get() or objcache_reclaimlist call (which use M_WAITOK and M_NOWAIT), it was just one big converting back and forth with some sanitization in between.
This commit allows M_* again for the mbuf functions and keeps the sanitizing as it was before: when M_WAITOK is among the passed flags, objcache functions will be called with M_WAITOK and when it is absent, they will be called with M_NOWAIT. All other flags are scrubbed by the MB_OCFLAG() macro which does the same as the former MBTOM().

if: Multiple TX queue support step 1 of many; introduce ifaltq subqueue
Put the plain queue information, e.g. queue header and tail, serializer, packet staging scoreboard and ifnet.if_start schedule netmsg etc. into its own structure (subqueue). ifaltq structure could have multiple of subqueues based on the count that drivers can specify.
Subqueue's enqueue, dequeue, purging and states updating are protected by the subqueue's serializer, so for hardwares supporting multiple TX queues, contention on queuing operation could be greatly reduced.
The subqueue is passed to if_start to let the driver know which hardware TX queue to work on. Only the related driver's TX queue serializer will be held, so for hardwares supporting multiple TX queues, contention on driver's TX queue serializer could be greatly reduced.
Bunch of ifsq_ prefixed functions are added, which is used to perform various operations on subqueues. Commonly used ifq_ prefixed functions are still kept mainly for the drivers which do not support multiple TX queues (well, these functions also ease the netif/ convertion in this step :).
All of the pseudo network devices under sys/net are converted to use the new subqueue operation. netproto/802_11 is converted too. igb(4) is converted to use the new subqueue operation, the rest of the network drivers are only changed for the if_start interface modification.
For ALTQs which have packet scheduler enabled, only the first subqueue is used (*).
(*) Whether we should utilize multiple TX queues if ALTQ's packet scheduler is enabled is quite questionable. Mainly because hardware's multiple TX queue packet dequeue mechanism could have negative impact on ALTQ's packet scheduler's decision.
