client: added global "expired" flag

Browse Source 
Patch bdeb8e14 ("client: moved "expired" accesses into inline
function") was created under the wrong assumption that
processListOfCommands() could modify the expired flag, which is not
the case.  Although "expired" is a non-const pointer,
processListOfCommands() just reads it, using it as the break condition
in a "while" loop.  I will address this issue with a better overall
solution, but for now provide a pointer to a global "expired" flag.
