paths: move path validation logic to its own function
Hard coding the '.hg' path in the paths class made it difficult for the hggit
extension to pull from gitrepos.
This patch moves the logic out to it's own function so extensions can add
additional checks to what is a valid path (i.e. a git repo is valid when hggit
is enabled).
