[BPF] Handle aliases in CodeGenModule::EmitExternalDeclaration. Fixes #192365 (#192374)
Adds handling of global aliases in
CodeGenModule::EmitExternalDeclaration. This fixes a clang crash on some
real code, see llvm#192365.
devel/py-lazyarray: New port
lazyarray is a Python package that provides a lazily-evaluated numerical
array class, larray, based on and compatible with NumPy arrays.
Lazy evaluation means that any operations on the array (potentially including
array construction) are not performed immediately, but are delayed until
evaluation is specifically requested. Evaluation of only parts of the array
is also possible.

[mlir][tensor] Remove unit-stride restriction in InsertSliceOp folding (#192600)
This PR replaces manual offset/size resolution with `affine::mergeOffsetsSizesAndStrides`, simplifying the code and extending subview-of-subview folding to support non-unit strides.
LinuxKPI: implement devm_kmemdup_array()

LinuxKPI: add kmalloc_obj[s], kzalloc_obj[s], and kzalloc_flex
Drivers in Linux v7.0 seem to have changed to the new allocation
macros using a sweep. Add the ones I encountered with wireless
drivers so far. They all take an optional argument for a gfp_t,
which default_gfp() deals with.
The plural version "objs" takes an extra nitems argument in addition
to the size. We use size_mul() to possibly detect overflows.
The "flex" version uses an extra variable to track the variable sized
array allocations and if supported by the compiler will use
__builtin_counted_by_ref() to properly track bounds.

LinuxKPI: conditionally add __flex_counter()
__flex_counter() is used by overflow.h and needed for "flex allocations".
It is either a void * typed 0 (NULL) (like this for _Generic checks),
or uses __builtin_counted_by_ref.
The latter was added to gcc and llvm fairly recently and while for gcc
the __has_builtin() check suffices, clang had parts broken until recently
so needs an extra check for the next major version. The fixed hash is
currently not part of any tag to use, so we play it save (and hope 23
will have it). It will be a while until we will see the builting to be
used but at least we will be prepared for it. See inline comments for
the commit hashes and versions which added the feature.

LinuxKPI: move hex2bin() from kernel.h to new hex.h
New Linux v7.0 drivers include hex.h. Rather than adding a dummy
header, migrate the kernel.h hex2bin() into hex.h, where it belongs.
Care needs to be taken as the _h2b() helper function is still used by
other bits in kernel.h.

LinuxKPI: add default_gfp()
Various new allocation macros can take an optional gfp_t argument.
If the argument is not given we need to set the GFP_KERNEL default.
While this is only internally used and I initialy called it differently,
should this spread elsewhere having the same name as in Linux will be
good.

LinuxKPI: 802.11: make sure dtim_period is set
When going from ASSOC to RUN LinuxKPI based wireless drivers have
certian expectations written in various ways. I believe mac80211
waits to see a beacon before setting the vif to assoc (or the sta
to AUTHORIZED). We have some comments in lkpi_update_dtim_tsf()
for that.
In practice we can filter out the beacons already and know when
they came in as we count them but it is hard to split up the
state machine and defer the work.
So we make sure that dtim_period is set to at least 1 before
calling the (*vif_cfg_change) after setting assoc to true;
0 is a reserved value according to the standards.
We will update it once we see a beacon and in case the value
differs from 1 shortly afterwards from the recv_mgmt callback.
While iwlwifi seems to have coped with our initial implementation,
