[Asyncweb client] a number of changes to migrate from the Geronimo sandbox

[Sangjin Lee]

We have been making a number of changes on the Geronimo sandbox side for the
AsyncHttpClient.  We've been meaning to move them over, but the pent-up
changes have grown to quite a few.  I haven't had time to sit down and
analyze whether certain bug fixes are applicable for the asyncweb codec.  I
hope I'll be able to do that some time this week or next week at the latest.
 Just a heads up for you...
