The configuration processing works as follows - the configuration
parameters are set in memory, and an apply function applies all the
changes directly to the device. While this works during startup and
reload, it adds a needless overhead when processing config set commands
from the command socket.
This change makes it such that a `config set` command would update the
configuration for that particular key, and then immediately call the
callback function for that key. This has the effect that individual
configuration changes are visible immediately, without having to reapply
every other configuration that hasn't changed.
This commit also removes the `config apply` command, since it is no
longer needed. The `config load` and `config reload` already handle
applying the configuration after reading it.
The command allows the client to retrieve individual parameters from the
configuration. This follows a similar syntax to the 'config set'
command, with the client supplying the section and key, and if there is
a matching entry in the configuration, it will return the corresponding
value.
This change allows setting the configuration from the socket. It behaves
similar to the override, and requires the client to send the section,
key and value, and responds with an OK or error value.
This change adds the daemon configuration parser and command line
argument parser. This also adds the associated strings to the
translation files, and integrates the daemon into the existing autotools
build framework.
