[orbitcpp-list] splitting ServantBase into 2 classes

[Phil d. <ph...@us...>]

Hi Andrew,

What was the rationale for ServantMethods not inheriting from
ServantBase?

The problem with the above is that the _this() method needs to be on a
ServantBase object or it can't activate itself with the default poa.

I've fixed this by making ServantMethods inherit virtually from
ServantBase again, so that code which uses _this() works, but I don't
know how these affects your inheritance scheme...

Cheers,

Phil.
