When incremental mode is enabled, adjust garbage collection to avoid
promoting objects from the next-to-oldest generation into the oldest
generation. This change produces a good approximation to incremental
collection for game-like programs (although probably not server-like
programs with large, temporary jobs).
Fix error checking and reporting for position-based struct accessors
and mutators. Also, fix mutability recording for prefab structure
types that have auto fields.

Re-enable scanbuild for 3m and CS, previously disabled in 9d89bbe909
There is a GitHub Actions but where inside a container variables `$HOME`, `$GITHUB_WORKSPACE`, `{{ runner.temp }}` are not properly set.
This commit contains some workaround that can be removed once a fix has been pushed from the GitHub side.
This is temporary until I can fix them. Unfortunately, I have no idea
what's going on on the Actions side. In the meantime I would like to
see green ticks for master commits.
Working on a fix under #3119
Implement 'atomic-interior allocation and immobile cells using
`make-immobile-bytevector` and `make-immobile-vector`, which avoids
having to unlock through a finalizer.
Also, the Chez Scheme GC can now mostly mark a major generation,
instead of copying it, which can significantly reduce memory
use during a GC for an old, large heap (such as DrRacket's).
Show peak administrative as a parenthesized delta on peak space.
For BC, this extra delta is small, because BC compacts (instead of
copying) old-generation objects. For CS, the extra delta can large ---
typically an extra 50%, but potentially another 100% --- because a
full collection copies all old-generation objects.
Also, for BC, fix cumulative-allocation reporting to include child
places.
Extract invert_limb code for ARM from GMP 6.2.
In order to check for thumb mode availability use defined macro `__thumb__`, which in turns requires us to process the source file with `gcc` instead of `as` in order to access the preprocessor - tested with `clang` as well.
Fixes#3050
The Chez Scheme change avoids a leak while collecting in counting
mode, which is used by Racket's memory-accounting mode.
Also, add a small repair for 4256214981.
GitHub switched URLs for tarballs, redirecting to the new one with
a 302. However, old versions of Racket don't follow redirects in
`raco pkg install`, so they broke (before 6.3). Using the new URL
should work for everyone.
Reported by @greghendershott.
Also `--include-deps`, which support the creation of a catalog archive
that is restricted to a specific set of packages. Also
`--fast-file-copy`, which is usefl for speeding up a pipeline of
archiving (helpful to pkg-build).
