* allow specifying number of versions when mirroring all packages

* when mirroring all specs within an environment, include dependencies of root specs

* add '--exclude-specs' option to allow user to specify that specs should be excluded on the command line

* add test for excluding specs

* add subcommand `spack view copy/relocate`

* update bash completions

* add copy/relocate commands to view tests

* allow copied views to be removed

* Implicit rpaths for NAG.

* set up environment when checking for implicit rpaths

fixes #12527

Mention that specs  can be uninstalled by hash also in
the help message. Reference `spack gc` in case people
are looking for ways to clean the store from build time
dependencies.

Use "spec" instead of "package" to avoid ambiguity in
the error message.

Fix message 'amber requires cuda version :10.1.243, but spec asked for 10.2.89'

* Unify tests for compiler command in the same file

Tests for the "spack compiler" command were previously
scattered among different files.

* Tests should use mutable_config, since they modify the compiler list

Add version 1.2.2.
Add conditional python dependency.
Add patch for 1.1.4.1 and python.

* Add ipython 7.5.0

* Update dependencies

* Update package.py

Because of the way abstract variants are implemented, the following 
spec matrix does not work as intended:
```
matrix:
- [foo]
- [bar=a, bar=b]
exclude:
- bar=a
```
because abstract variants always satisfy any variant of the same
name, regardless of values.

This PR converts abstract variants to whatever their appropriate 
type is before running satisfaction checks for the excludes clause 
in a matrix.

fixes #16841
