[v2,0/7] (mainly) xz imports from Linux

While going through their 5.15.3 log I did notice two changes, which made
me go check what else we might be missing. The series here is the result.
Linux has also updated zstd, but that includes a pretty large change which
I'm not ready to deal with right now. Them moving closer to the upstream
zstd sources is certainly a good thing, so I suppose sooner or later we
will want to follow them in doing so.

The only change in v2 is the re-adding of some previously dropped S-o-b
representing the original, documentable submission flow.

1: xz: add fall-through comments to a switch statement
2: xz: fix XZ_DYNALLOC to avoid useless memory reallocations
3: decompressors: fix spelling mistakes
4: xz: avoid overlapping memcpy() with invalid input with in-place decompression
5: xz: fix spelling in comments
6: xz: move s->lzma.len = 0 initialization to lzma_reset()
7: xz: validate the value before assigning it to an enum variable

Oh, actually there was another (benign) change:

The last three have been switched around to match the sequence they went
into upstream Linux (IOW the order spelled out above does not match the
actual series; I'm sorry).
