[omniORB] global servant activator task queue [revisited]

[Teemu Torma]

If anyone is interested.

Some time ago I asked if there is a good reason why the servant 
activator task queue is global instead of per-poa.  Since Duncan's 
reply in 
http://www.omniorb-support.com/pipermail/omniorb-list/2006-July/027880.html 
was inconclusive, we implemented a patch to move it to the poa level.

Works fine and haven't seen any ill-effects.  The patch is against 4.0.5 
but should apply cleanly to 4.1.  The size of the patch is bigger than 
actual changes due to code moved around.
