The NVMe specification does not define a maximum or optimal delete
size, so technically max delete size is min(full size of namespace,
2^32 - 1 LBAs). A single delete operation for a multi-TB NVMe
namespace though may take much longer to complete than the nvme(4)
I/O timeout period. So choose a sensible default here that is still
suitably large to minimize the number of overall delete operations.
This also fixes possible uint32_t overflow on initial TRIM operation
for zpool create operations for NVMe namespaces with >4G LBAs.

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

Several attempts to fix this logic was done after r241298, which were
all reverted, yet this change was not.
The .h file does not depend on the .c file, so do not impose such a
dependency on it. They are generated by the same command but do not
depend on each other. Restore the .ORDER which should handle parallel build
issues. This fixes an actual bug where the .h file is not recreated
when missing [1]. For example:
cd lib/libc
make cleanobj
make nsparser.h
rm nsparser.h
make nsparser.h # will not rebuild nsparser.h
I have been trying to track down a build problem where nsparser.h is
missing when nslexer.o is built. It is possible this is related.

DIRDEPS_BUILD does not yet support PROGS having their own dependency
file.
Overriding .MAKE.DEPENDFILE here causes major problems with the meta
mode logic since it creates the Makefile.depend as '.depend' resulting
in infinite loops in make due to dirdeps.mk including .depend endlessly.

We have had this user-modifable DEPENDFILE variable forever that does nothing
relevant for the user since fmake always used '.depend'. Bmake
introduced the .MAKE.DEPENDFILE variable that can be modified to change
the name of '.depend'.
Prior to r284288, bsd.progs.mk was setting .MAKE.DEPENDFILE to allow
working incremental builds. This was modified most likely to not
conflict with the META MODE handling of .MAKE.DEPENDFILE as it has a lot
more special logic for that variable.

This fixes incremental build of OpenSSH after the recent upgrade.
For example, in secure/lib/libssh, -include ssh_namespace.h is used on
all files. This is not tracked in the .depend file though due to
MKDEP_CFLAGS not including it. The ssh example was broken in r291941
when not using FAST_DEPEND due to the .depend bug. FAST_DEPEND was not
affected by this because it generates dependencies at compile time and
thus sees the -include.
This ugly make syntax could be simpler for bmake by using :tW but
fmake-compatible syntax is used since this needs to be MFC'd all the way
to stable/9.
Also add a temporary hack to workaround existing checkouts building
incrementally with a .depend file not having these headers.

This was a regression in r290629, which was revealed partly in r294360.
Once 'make depend' has ran it will generate all headers already. Thus
even with FAST_DEPEND lacking proper dependencies before building, it
will not have any missing headers. Once objects are compiled the depend
files will be generated with proper dependencies.

This reworks r289254 and removes ALL_SUBDIR_TARGETS.
Because there is an include guard in this file there is no need for
LOCAL_ or ?= on SUBDIR_TARGETS or STANDALONE_SUBDIR_TARGETS. These can
just be set via src.conf. By the time bsd.subdir.mk is included it will
just append the values to the existing value and work fine. This allows
a consistent way to append to these variables without introducing a
LOCAL_ var for STANDALONE_SUBDIR_TARGETS or renaming the historical
SUBDIR_TARGETS.

If filemon is used then there is no need to generate dependency files during
compilation as the .meta files will achieve the same result.
This is a temporary solution until FAST_DEPEND is default. Once that is
default there will be an option to disable dependency generation entirely
as it is only useful if an incremental build is planned, thus META_MODE+filemon
can enable that option to short-circuit all FAST_DEPEND-related logic.

This API has no in-tree consumers at the moment but is useful to at least
one out-of-tree consumer, and naturally complements existing vnode refcount
