libpthread, but still quite useful in libpthread as it can be used to
process interlaced records from multiple threads over the course of a
system call.
Detect old ktr_buffer values using the heuristic "if it's negative,
then it must not be a valid threadid". This may leave something to be
desired.

intptr_t. The buffer length needs to be written to disk as part
of the trace log, but the kernel pointer for the buffer does not.
Add a new ktr_buffer pointer to the kernel-only ktrace request
structure to hold that pointer. This frees up an integer in the
ktrace record format that can be used to hold the threadid,
although older ktrace files will have a garbage ktr_buffer field
(or more accurately, a kernel pointer value).

This will allow cpio archive support to work, at least in situations

since the link takes a bit to negotiate, the information is pretty
much never available during the probe. As such, the boot output
pretty much always prints N/A for speed and duplex. Since we print
out the output of ifconfig during the user space boot, this early
boot information is also generally redundant, and added to the noise.

a valid hash table, and would cause a kernel panic when they were loaded.
Instead of panic'ing, the kernel now prints out a warning that it is
missing the symbol hash table.

PCI-ISA bridge. Thus, when viapm0 or viapropm0 attaches, isab0 dosen't
attach so there is no isa0 bus hung off of that bridge. In the non-ACPI
case, legacy0 will add an isa0 anyway as a fail-safe, but ACPI assumes that
any ISA bus will be enumerated via a bridge. To fix this, call
isab_attach() to attach an isa0 ISA child bus device if the pm or propm
device we are probing is a PCI-ISA bridge. Both drivers now have to
implement the bus_if interface via the generic methods for resource
allocation, etc. to work. Also, we now add 2 new ISA bus drivers that
attach to viapm and viapropm devices.

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.
- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.
- Disambiguate some collisions by adding subsystem prefixes to some
memory types.
- Generally prefer lower case to upper case.
- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.
Not all instances were caught in this change, so more work is required to
