Simplify ng_pipe locking model by relying on the netgraph framework to provide serialization of calls into the node, which is accomplished by markng the node as single-threaded (NGF_FORCE_WRITER). The price we pay is that each ng_pipe instance now has its own callout handler which polls for queued frames on each clock tick, as long as the pipe has any frames in its internal queues. OTOH, we got rid of the global ng_pipe mutex, so from now on multiple ng_pipe instances can operate in parallel. This change also fixes counting of forwarded frames when an ng_pipe node is not enforcing any packet impairments. While here, attempt to improve adherance to style(9) throughout otherwise mostly unreadable code.

Allow for MTU sizes of up to ETHER_MAX_LEN_JUMBO (i.e. 9018) bytes to be configured on ng_eiface ifnets. The default MTU remains unchanged at 1500 bytes. Mark ng_eiface ifnets as IFCAP_VLAN_MTU capable, so that the associated vlan(4) ifnets may use full-sized Ethernet MTUs (1500 bytes).

Add new tunable 'net.link.ifqmaxlen' to set default send interface queue length. The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file. Also add read-only sysctl with the same name, so that it's possible to retrieve the current value.
