Decrease bio_children manually when destroying bios.

lines of code duplication, but it provides a significant performance
improvement because it avoids recursing on callout_lock.

unless we are actually using inpcb fields other than the bound port
and address. Since we hold the pcbinfo lock already, these can't
change. Defer acquiring the inpcb mutex until we have a high
chance of a match. This avoids about 120 mutex operations per UDP
broadcast packet received on one of my work systems.

There seems to be some confusion in the syscons code as to the meaning of
the SC_KERNEL_CONSOLE flag. Its absence is sometimes interpreted to mean
"I am not the system console", and sometimes to mean "I am not the only
VGA console" (see the font loading code for an example of the latter).
Someone with better syscons fu than myself should take a closer look.

better check for 'adjacent'. The old code assumed that if two resources
were adjacent in the linked list that they were also adjacent range wise.
This is not true when a resource manager has to manage disparate regions.
For example, the current interrupt code on i386/amd64 will instruct
irq_rman to manage two disjoint regions: 0-1 and 3-15 for the non-APIC
case. If IRQs 1 and 3 were allocated and then released, the old code
would coalesce across the 1 to 3 boundary because the resources were
adjacent in the linked list thus adding 2 to the area of resources that
irq_rman managed as a side effect. The fix adds extra checks so that
adjacent unallocated resources are only merged with the resource being
freed if the start and end values of the resources also match up. The
patch also consolidates the checks for adjacent resources being allocated.
