The tracking database can be opened in read-only or read-write
mode. Knowing which is being used is significant in concurrent
scenarios, e.g. it's safer to have a read-only handle on multiple
threads.
Provide static type information by signifying what kind of database
handle is being worked with, read or read-write.

This is a fairly substantial change, which adds a new configuration file
to the user's `$RAD_HOME` that includes node configuration, including
the alias, and also makes node aliases required.
When running `rad auth`, the user is now prompted for an alias, which
defaults to `$USER`.
When running `rad self`, the alias is now shown.
If the user runs radicle without a config file, the defaults are loaded,
and `$USER` is used as the alias.
* Return the correct alias from a node announcement, stripping '\0'
bytes.
* Accept `AliasStore` types as references and as owned.
* Store a `null` in the database if the alias received is empty.
This fixes an issue that came up in tests where we would be reading
and writing to the database at the same time, and it would fail with
an error due to the lock being contended on.
