Instead of the account details, a pointer to the C structure is used in
Lua, stored as light userdata.
The 1.x deprecated configuration format has been removed, partly due to
the above change, and partly because it has been included for long

The whole function that implements a request needs to be called again,
when there is a failure that leads to re-login, and not just the last
receive or send function that failed.
Move the source code to the src dir, the man pages to the doc dir, and
the example configuration files to the samples dir, and update all
relevant files to reflect the changes.
