update TODO
kmod: move #ifdef checks for kmod-setup out of main.c into kmod-setup.c
kmod-setup: improve for "kdbus" word on the kernel cmdline

We really shouldn't check for words with "strstr()"...
bus-proxy: drop broken access check in driver

The access check call was broken (as it tried to read a service name
from the UpdateActivationEnvironment() method call which doesn't carry
any). Also, it's unnecessary to make any access checks here, as we just
forward the call to PID 1 which should do the access checks necessary.
bus-proxy: properly check for bus name prefixes when enforcing policy
bus-proxy: avoid redundant name validity checks

Our API calls check the validity of bus names anyway, hence we don't
have to do this before calling them...
