commit8a30653ed5introduced a sync.Once to allow for the config-directory (and home-dir) to be looked up lazily instead of in an `init()`. However, the package-level `configDir` variable can be set through two separate paths; implicitly (through `config.Dir()`), and explicitly, through `config.SetDir()`. The existing code had no synchronisation for this, which could lead to a potential race-condition (code requesting `config.Dir()` and code setting a custom path through `config.SetDir()`). This patch adds synchronisation by triggering the `sync.Once` as part of `config.SetDir()` to prevent it being triggered later (overwriting the value that was set). It also restores the `resetConfigDir()` utility that was removed in379122b033, to allow resetting the `sync.Once` for this test. In general, we should get rid of this package-level variable, and store it as a config on the client (passing the option to locations where its used instead).
