Implement basic netrc parser

mfriedenhagen commented 10 years ago

I just implemented a .netrc parser as I quite often use Python or Curl and have authentication information already in this form. No need to introduce another place to store passwords :grin:

A format description may be found at http://linux.die.net/man/5/netrc.
I based the implementation for now on the one I found in Python.
As I have never used account or macdef before, I decided to just drop support for these.
UTF-8 umlauts and multi-line .netrc are supported.

According to Wikipedia the Python license PSF should work fine with Apache 2.0.

This PR includes resp. supersedes #3.

Thank you for your contribution!

I've merged your code and added a rough integration for webdav nodes. Can you check if that's what you need?

Do you think I should also integrate it into SshNodes? And maybe also replace passphrase files by netrc support?

I want to rename NetRcParser to NetRc, is that ok for you?

@mlhartme:

I will take a look on your integration in the master branch.
IMO it is better to have exactly one password file like .netrc, so everyone knows what permissions are needed.
I will take a look into SshNodes this evening and probably it would be good to use .netrc here as well.
I am completely fine with renaming the Parser class.
I could add a manual test which parses $HOME/.netrc so we have an example here how to use the class :grin:
