Add queue(2) debug macros as build options

Add QUEUE_MACRO_DEBUG_TRACE and QUEUE_MACRO_DEBUG_TRASH as proper kernel
options. While here, alpha-sort the debug section of sys/conf/options.

Enable QUEUE_MACRO_DEBUG_TRASH in amd64 GENERIC (but not GENERIC-NODEBUG)
kernels. It is similar in nature and cost to other use-after-free pointer
trashing we do in GENERIC. It is probably reasonable to enable in any arch
GENERIC kernel that defines INVARIANTS.

Set MALLOC_DEBUG_MAXZONES=1 in GENERIC-NODEBUG configurations.

The purpose of this option is to make it easier to track down memory
corruption bugs by reducing the number of malloc(9) types that might
have recently been associated with a given chunk of memory. However, it
increases fragmentation and is disabled in release kernels.

Extract the coverage sanitizer KPI to a new file.

This will allow multiple consumers of the coverage data to be compiled
into the kernel together. The only requirement is only one can be
registered at a given point in time, however it is expected they will
only register when the coverage data is needed.

A new kernel conflig option COVERAGE is added. This will allow kcov to
become a module that can be loaded as needed, or compiled into the
kernel.

While here clean up the #include style a little.

Add BUF_TRACKING and FULL_BUF_TRACKING buffer debugging

Upstream the BUF_TRACKING and FULL_BUF_TRACKING buffer debugging code.
This can be handy in tracking down what code touched hung bios and bufs
last. The full history is especially useful, but adds enough bloat that
it shouldn't be enabled in release builds.

Function names (or arbitrary string constants) are tracked in a
fixed-size ring in bufs. Bios gain a pointer to the upper buf for
tracking. SCSI CCBs gain a pointer to the upper bio for tracking.

This configuration file removes several debugging options, including
WITNESS and INVARIANTS checking, which are known to have significant
performance impact on running systems. When benchmarking new features
this kernel should be used instead of the standard GENERIC.
This kernel configuration should never appear outside of the HEAD
of the FreeBSD tree.
