Merge branch 'ls/p4-path-encoding'

"git p4" learned to reencode the pathname it uses to communicate
with the p4 depot with a new option.

* ls/p4-path-encoding:
git-p4: use replacement character for non UTF-8 characters in paths
git-p4: improve path encoding verbose output
git-p4: add config git-p4.pathEncoding
