[RFC PATCH 0/8] btrfs: convert to fscontext

[Marcos Paulo de Souza <marcos@mpdesouza.com>]

From: Marcos Paulo de Souza <mpdesouza@suse.com>

These patches aim to convert btrfs to new fscontext API. I used the approach of
creating a new parsing function and then switching to this new function, instead
of creating a huge change patch. Please let me know if you think this is a
better approach.

The most notable changes come form the fact that now we parse the mount options
before having a fs_info, in the same way that David Howells did in his POC[1]
some time ago.
