makeman doesn't handle this since it would need to enable all
non-default options when checking enabling 1 option, which
then convolutes what is really affecting each other.
This fixes build failures on older releases that lack various
definitions such as EM_AARCH64 (which was unfixed before this).
Revert all of the recent compatibility changes that worked around this
problem.
This uses the same method of using the in-tree header as lib/libelf,

CCACHE_DIR needs to be resolved to its full path before processing
legacy.meta or meta mode may see the change to the stats file.
Sponsored by: EMC / Isilon Storage Division
The WITH_META_MODE build is intended to be a working incremental build.
It spies on the build command to see if things should be rebuilt if the
command changes. If you run buildworld, it builds a cross-compiler,
then do installworld and buildworld again it will invoke the
WITH_SYSTEM_COMPILER logic. This then adds on -target/--sysroot, etc,
and causes rebuilds due to the changed build command even though the
compiler used is technically the same revision. Since the incremental
build is not cleaning anything by default then there is much
less risk to rebuilding the already-existing cross-compiler. Just
disable the combined logic and always use and build the cross-compiler.
An alternative to this would be to always pass -target/--sysroot. Doing
so may occur in the future.

Using buildworld, installworld, buildworld. It is expected that nothing
should rebuild. However any host tool used could have its timestamp
updated. Any library used by dynamic tools could have its timestamp
updated. The filemon(4) data in the .meta files captures all reads to
these files. This causes the 2nd buildworld to rebuild everything since
host tools and files have been updated.
Because the build is self-reliant and bootstraps itself, it should be
safe to ignore mtime changes on host files used during the build. Host
files should only impact the build of legacy, build-tools, bootstrap-tools,
cross-tools, but those are already intended to be reproducible from its
own bootstrapping. It is possible in a rare case that a bug in a host
file does produce a broken build tool. If that happens it will just
have to be communicated properly.
An alternative solution would be to update the mtime of all files in the
object directory after installworld so that the host files are not newer
than the object files. That also requires special care for read-only
obj directories and special care to not mess with any intended timestamps in
the build, such as done for reproducibility.

When collation support was brought in, the second and third
arguments in __collate_range_cmp() were changed from int to
wchar_t, breaking the ABI. Change them to a "char" type which
makes more sense and keeps the ABI compatible.
Also introduce __wcollate_range_cmp() which does work with wide
characters. This function is used only internally in libc so
we don't export it. Use the new function in glob(3), fnmatch(3),
and regexec(3).

p_sched is unused.
The struct td_sched is always co-allocated with the struct thread,
except for the thread0. Avoid useless indirection, instead calculate
td_sched location using simple pointer arithmetic in td_get_sched(9).
For thread0, which is statically allocated, create a structure to
emulate layout of the dynamic allocation.

BUS_MAP_INTR() is used to get an interrupt mapping data according
to provided hints. The hints could be modified afterwards, but only
if mapping data was allocated. This method is intended to be called
before BUS_ALLOC_RESOURCE().
An interrupt mapping data describes an interrupt - hardware number,
type, configuration, cpu binding, and whatever is needed to setup it.
(2) Introduce a method which allows storing of an additional data
in struct resource to be available for bus drivers. This method is
convenient in two ways:
- there is no need to rework existing bus drivers as they can simply
be extended to provide an additional data,
- there is no need to modify any existing bus methods as struct
resource is already passed to them as argument and thus stored data
is simply accessible by other bus drivers.
For now, implement this method only for INTRNG.
This is motivated by needs of modern SOCs where hardware initialization
is not straightforward and resources descriptions are complex, opaque
for everyone but provider, and may vary from SOC to SOC. Typical
situation is that one bus driver can fetch a resource description for
its child device, but it's opaque for this driver. Another bus driver
knows a provider for this kind of resource and can pass this resource
description to it. In fact, something like device IVARS would be
perfect for that if implemented generally enough. Unfortunatelly, IVARS
are usable only by their owners now. Only owner knows its IVARS layout,
thus other bus drivers are not able to use them.

o meta.c: refactor need_meta decision, add knobs for
missing meta file and filemon data wrt out-of-datedness.
o meta.c: missing filemon data is only relevant if we read a
meta file.
Also do not return oodate for a missing metafile if gn->path
