doc: align the early testers program description with its goal

feat: add --long as alias for -l in files.ls

Allow passing --long or ?long=true as a more descriptive option name than "l".

switch to new merkledag walk functions

EnumerateChildrenAsync has been renamed to WalkParallel to reflect the fact
that:

1. It visits the root.
2. It's parallel, not async.

To mirror this change, EnumerateChildren has also been renamed to Walk and now
behaves the same (except that it's not parallel).
