Add indirection for large version vectors. (#6376)
This adds indirection of large version vectors in the same manner as we
already to block lists. The effect is the same: less duplicated data in
some situations.

To mitigate the impact for when this indirection
wouldn't be needed I've added an indirection cutoff for both blocks and
the new version vector stuff: we don't do the indirection at all for
small block lists or small version vectors, instead storing it directly
like we used to do. This is faster for small files and small setups.

4d3e0de4ba cmd/syncthing, lib/sha256: Skip CPU benchmarks when user decided (fixes #4348)
When STHASHING is set, don't benchmark as it's already decided. If weak
hashing isn't set to "auto", don't benchmark that either.

6d4fa27ea7 cmd/syncthing: Report real hashing performance, including weakhash
Instead of

    [I6KAH] 19:05:56 INFO: Single thread hash performance is 359 MB/s using minio/sha256-simd (354 MB/s using crypto/sha256).

it now says

    [I6KAH] 19:06:16 INFO: Single thread SHA256 performance is 359 MB/s using minio/sha256-simd (354 MB/s using crypto/sha256).
    [I6KAH] 19:06:17 INFO: Actual hashing performance is 299.01 MB/s

which is more informative. This is also the number it reports in usage
reporting.

d328e0fb75 cmd/syncthing: Add selectable sha256 package (fixes #3613, fixes #3614)
This adds autodetection of the fastest hashing library on startup, thus
handling the performance regression. It also adds an environment
variable to control the selection, STHASHING=standard (Go standard
library version, avoids SIGILL crash when the minio library has bugs on
odd CPUs), STHASHING=minio (to force using the minio version) or unset
for the default autodetection.
