manifest: refactor the filesystem checking logic for more reuse

This function is currently written with copyfile & linkfile in mind.
Generalize the logic & function arguments slightly so we can reuse
in more places that make sense.

This changes the validation logic slightly too in that we no longer
allow "." for the dest attribute with copyfile & linkfile, nor for
the src attribute with copyfile.  We already rejected those later on
when checking against the active filesystem, but now we reject them
a little sooner when parsing.

The empty path check isn't a new requirement exactly -- repo used to
crash on it, so it was effectively blocked, but now we diagnosis it.

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Contact

Please use the repo-discuss mailing list or issue tracker for questions.

You can file a new bug report under the “repo” component.

Please do not e-mail individual developers for support. They do not have the bandwidth for it, and often times questions have already been asked on repo-discuss or bugs posted to the issue tracker. So please search those sites first.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo
