Now that the common configuration objects and session objects are part
of a public API, they need to be documented in a way that can be read
with godoc. This commit should lead to easier development with FRP as a
library.
The ClientCommonConf, configuration file path, and server UDP port are
now passed around as arguments instead of being shared between
components as global variables. This allows for multiple clients to
exist in the same process, and allows client.Session to be used as a
library more easily.
This option allows users to specify where they want assets to be loaded
from, like the "assets_dir" option that already exists for frps. This
allows library users to use the admin panel without having to bundle
assets with statik.
The ServerCommonConf is now passed around as an argument instead of
being shared between components as a global variable. This allows for
more natural interaction with server.Session as a library and allows for
multiple servers to co-exist within the same process.

The client and server services now only attempt to load assets if the
dashboard or admin panel are enabled. This change makes it possible to
use FRP as a library without having to manage assets. If a library user
wants to start a server with the dashboard enabled, they will need to
set the DashboardPort and AssetsDir fields of ServerCommonConf.
