copies: add a HASCOPIESINFO flag to highlight rev with useful data
If some files changes that may impact copy tracing are detected, we set this
flag. This helps the copy tracing algorithm to skip fetching possibly expensive
data when unnecessary.

Verify status only shows included files

Adding an excluded file should fail
$ hg add hide3
abort: cannot add 'hide3' - it is outside the sparse checkout
(include file with `hg debugsparse --include <pattern>` or use `hg add -s <file>` to include file directory while adding)
[255]
But adding a truly excluded file shouldn't count
$ hg add hide3 -X hide3
Verify deleting sparseness while a file has changes fails
$ hg debugsparse --delete 'show*'
pending changes to 'hide'
abort: cannot change sparseness due to pending changes (delete the files or use --force to bring them back dirty)

Test debugdirstate --minimal where a file is not in parent manifest
but in the dirstate. This should take into account excluded files in the
manifest

We have files in the dirstate that are included and excluded. Some are in the
manifest and some are not.
