Delete forked function_traits

The function_traits class was very clearly "borrowed" from
boost::function traits, then added to to support lambdas.
boost::function_traits has been superceeded by boost::callable_traits,
which fixes the same shortcomings that we have fixed here.

This commit replaces almost the entirety of the uses of function_traits
with callable traits, with one exception: arg<i>.  In the callable
traits model, arg_t is a std::tuple, which, while better, doesn't unpack
easily into a variadic pack that our router code expects.  Ideally, at
some point, we would rewrite the router core to not rely on
std::make_integer_sequence, but that's a much more invasive change.

Tested:
Called
curl --insecure --user root:0penBmc https://192.168.7.2/redfish/v1/Managers/bmc/LogServices/Journal/Entries/1646953359619803
and verified callback return the correct result (not 404).  That API has
several flexible router parameters, which is the only thing this commit
could break.
