[cmucl-imp] ASDF 2.32 released

[Faré]

Dear CMUCL hackers,

ASDF 2.32 was released in time for inclusion in the upcoming CCL 1.9.

Once again, we invite all implementation vendors and distributors
to upgrade the version of ASDF included in their releases.

Yes, I know, that's a lot of releases in a bit more than a month.
But it was also a lot of development, and a lot of adjustment to reality
after that development was first released.
We will keep fixing bugs and improve ASDF based on
our growing internal test suite and results from Anton Vodonosov's cl-test-grid.

This is still a pre-release for ASDF3. Here are the changes,
since previous release 2.31, and since previous public announcement for 2.30.

>From 2.31 to 2.32:
  * deferred-warning checks are now disabled by default,
    to enhance backward compatibility with ASDF 2.26 and earlier.
    In the future, we will enable them by default,
    but not until we implement a smoother transition plan.
    Also, CCL-specific fixes to deferred-warning support.

  * UIOP is the new official name for ASDF-DRIVER.
    "Utilities for Implementation- and OS- Portability".
    Old names remain as package and system nicknames:
        ASDF/DRIVER ASDF-DRIVER ASDF-UTILS

  * require-system so systems may depend on implementation-provided modules.

  * auto-upgrade attempt in operate *before* the implicit find-system.

  * class specification for components can now be a string to be read
as a symbol.

  * feature conditional dependencies are now debugged and tested:
        :depends-on ("some-system" (:feature :foo "other-system))
    we only recommend them for dependencies between systems;
    within systems, we recommend you use feature-conditional components with
        :if-feature :foo
    and we only provide limited support for the deprecated legacy way of using
    feature-conditionals with a module having :if-component-dep-fails :ignore
    while its components specify things like:
        :in-order-to ((compile-op (feature :foo)))

  * read-from-file for :version specification is made more useful by using
    the ASDF-USER package rather than CL (into which interning is forbidden)
    to read the files.

Changes from 2.30 to 2.31:

  * *default-encoding* is now UTF-8. As tested with cl-test-grid,
    This is a boon for most programs,
    that will compile in a more predictable way in a wider range of settings.
    A handful of unmaintained outliers still need to be fixed.

  * Downgrade is now explicitly avoided. ASDF will issue a warning
    if your system is misconfigured in a way that specifies downgrade,
    but will then ignore the specified ASDF downgrade.

  * version specifications, when invalid, will lead only to a warning for now;
    a future ASDF3 may restore the behavior of ASDF 2.27,
    that raises an errors when there is a bad :version specification,
    but for now, backward compatibility prevails.

  * ECL support received several bug fixes.

  * precompiled-system support was notably fixed, enabling single-fasl
    deployment of SBCL contribs.
