Benoit Masson 74f9cd8da2 AllKeys() includes all keys / AllSettings() includes overridden nested values
* Function AllKeys() now returns all keys holding a value (for nested values,
  the nested key is the full path, i.e., a sequence of dot-separated keys).
  Previously, returned only depth-1 keys, as well as flags and environment
  variables: this is more generic and may be used widely.
  Besides, it takes into account shadowed keys (key ignored if shadowed by
  a path at a higher-priority level).

* Function AllSettings() now returns nested maps for all keys holding a value,
  as specified by AllKeys().
  The value stored in the map is the one with highest priority, as returned
  by the Get() function (taking into account aliases, environment variables,
  flags, etc.).

This fixes Unmarshal(): it fills in correct values for nested configuration
elements overridden by flags or env variables.

+ tests fixed accordingly
+ test added to TestShadowedNestedValue(), to test Unmarshalling of shadowed keys
