When potentially adding the `--disable-lib` flag, don't drop existing
extra configure flags. Specifically, the `--enable-crossany` flag
from distro-build could get lost, which breaks a soutrce distribution
with built packages.
Don't try to park values when allocating a weak box or pair in a
future thread, since that creates a race on the parking spaces. A
future thread can't run a GC, so it's doesn't need to park.
Touching a future in a future allocates a weak box, so this bug could
have been responsible for many crahses.

Update GMP license statment following 392dc33ceb which comes from
a recent GMP version.
This does not affect the overall license situation of Racket BC,
which includes other LGPL v3 code, or of Racket CS, which does not
use GMP.
The `call-with-deep-time-limit` function in `racket/sandbox` expects a
subprocess to be removed from its custodian when the subprocess is
done. CS wasn't doing that at all, leaving custodian removal to a
finalizer. BC was doing delaying a remove until `subprocess-status` is
used (which happened to work for existing uses of
`call-with-deep-time-limit`, apparently.)

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).
