We currently throw a nasty error if you try to reuse packages from some other namespace
(e.g., OLCF), but we should be able to reuse patched local versions of builtin packages.
Right now the only obstacle to that is that we try to look up virtual info for unknown
namespaces, and we can't get the package from the repo to do that. We *can* assume that
a package with a known namespace is similar, and that its virtual provider information
is reasonably accurate, so we now do that. This isn't 100% accurate, but neither is
relying on the package itself, as it may have gone out of date.
The real solution here is virtual edge information, but this is a stopgap until we have
that.
`spec_clauses()` attempts to look up package information for concrete specs in order to
determine which virtuals they may provide. This fails for renamed/deleted dependencies
of buildcaches and installed packages.
This will eventually be fixed by #35258, which adds virtual information on edges, but we
need a workaround to make older buildcaches usable.
- [x] make an exception for renamed packages and omit their virtual constraints
- [x] add a note that this will be solved by adding virtuals to edges
The concretizer can fail with `reuse:true` if a buildcache or installation contains a
package with a dependency that has been renamed or deleted in the main repo (e.g.,
`netcdf` was refactored to `netcdf-c`, `netcdf-fortran`, etc., but there are still
binary packages with dependencies called `netcdf`).
We should still be able to install things for which we are missing `package.py` files.
`Spec.inject_patches_variant()` was failing this requirement by attempting to look up
the package class for concrete specs. This isn't needed -- we can skip it.
- [x] swap two conditions in `Spec.inject_patches_variant()`
I will follow this up with a variant to flux-core to add flux-security, and then automation in the flux-framework/spack repository.

The @= in `spack find` output adds a bit of noise. Remove it as we
did for `spack spec` and `spack concretize`.
This modifies display_specs so it actually covers other places we use that routine, as
well, e.g., `spack buildcache list`.
before:
```
-- linux-ubuntu20.04-aarch64 / gcc@=11.1.0 -----------------------
ofdlcpi libpressio@0.88.0
```
after:
```
-- linux-ubuntu20.04-aarch64 / gcc@11.1.0 -----------------------
ofdlcpi libpressio@0.88.0
```
If a user does not explicitly `--force` the concretization of an entire environment,
Spack will try to reuse the concrete specs that are already in the lockfile.
