libpkg: attempt config file merge for force install
Currently `pkg install -f` always overwrite config files.
This commit changes this behavior to attempt to merge them.

libpkg: fix --register-only to populate config file contents
Currently `pkg install --register-only` does not acutally populate
config file contents in the pkg database. This leads to config files
potentially getting silently overwritten during upgrade/reinstall.

tests: add failing test that should pass
pkg install --register-only followed by pkg install -f should
merge config files, but it currently does not.
Fixing this behavior will allow pkgbasify to be simpler and more robust.

tunefs: Don't combine GEOM journaling with SU
GEOM journaling shouldn't be used at the same time as soft updates, so

kernel: Be clearer about what ZSTDIO is for
ZSTDIO is not just for core dumps, and it is now required by ZFS, so
move it (and GZIO, which is still just for dumps) to a new “Compression
support” section in GENERIC, and add them both to MINIMAL.

alloca.3: Add entry about defining VLAs in same block as alloca() to BUGS
Refer to alloca() as a (builtin) function or macro, as it could be
defined as either depending on the compiler.
Paragraph about bug comes from Darwin's libc, and example added to
illustrate it.

[mlir][SPIRV] Add alignment calculation to support `PhysicalStorageBuffer` with vector types (#187698)
This allows to lower `memref.load`/`store` operations on
`PhysicalStorageBuffer`-typed resources with the underlying type being a
vector type. This improves support for the `PhysicalStorageBuffer`
capability in pipelines that use the Vector dialect for distribution.

Continuing the trend of registering one `anyOf` matcher being slower
than registering each of its matchers separately (see #178829 for a
previous example).
(This PR also changes the traversal mode, but I only saw a small speedup
from that. Most of it came from registering the matchers separately.)
This check wasn't super expensive to begin with, but the speedup is
still pretty nice.

[NVPTX] Print param space sub-qualifiers where supported (#187350)
Print param space sub-qualifiers (`param::entry` and `param::func`) for
PTX 8.3+, as described in the [PTX ISA
docs](https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#parameter-state-space).
This requires threading the `MCSubtargetInfo` through the inst printer,
which is done by setting `PassSubtarget = 1` on the asm writer.
Emitting the full space avoids the need for ptxas to infer it, improving
readability and more importantly preventing potential bugs if valid LLVM
IR transformations were to move a load from ADDRESS_SPACE_ENTRY_PARAM
into a device function.

sys_mincore: stop locking potentially huge amount of user memory
the current implementation performs uvm_vslock() on the
user-specified amount of memory. it isn't safe in general.
some might even consider it as a security issue.
this commit fixes it by splitting the user-specified range into
small ones which a temporary kernel buffer can cover. it's ok to
report potentially stale values as the mincore() api is inherently
racy in the first place.
while we still ought to invent a proper "lock user memory for
direct i/o" infrastructue, in this particular use case, it isn't
necessary or appropriate.
