maintain set of files pendingAdd Kqueue needs to remember which files failed to be added due to being open, and retry them. This commit gets the data in place for such a retry thread. Broke KeySource out into its own file, and added Eq and Ord instances so it can be stored in a Set.

add: Improved detection of files that are modified while being added. In indirect mode, now checks the inode cache to detect changes to a file. Note that a file can still be changed if a process has it open for write, after landing in the annex. In direct mode, some checking of the inode cache was done before, but from a much later point, so fewer modifications could be detected. Now it's as good as indirect mode. On crippled filesystems, no lock down is done before starting to add a file, so checking the inode cache is the only protection we have.

{- When content is in the process of being added to the annex,

- The contentLocation may be different from the filename

crippled filesystem support, probing and initial support git annex init probes for crippled filesystems, and sets direct mode, as well as `annex.crippledfilesystem`. Avoid manipulating permissions of files on crippled filesystems. That would likely cause an exception to be thrown. Very basic support in Command.Add for cripped filesystems; avoids the lock down entirely since doing it needs both permissions and hard links. Will make this better soon.
