[roll] Roll fuchsia [xhci] Refactor transfer event handling

More aggressively refactor the transfer event handler code to add more
logging to assist with future debugging, and add asserts to check for
conditions that indicate driver bugs.

Some behaviour has been changed here, particularly concerning how we
handle event TRBs that don't point to a transfer TRB. There are some
event types that we don't handle, and previously they would flush out
all pending TRBs. This patch removes that behaviour, which might be
risky, but in some cases when we did that previously it would cause
upstream drivers to livelock. Eventually we should ensure that we're
correctly handling all event completion codes correctly and the
additional logging here should help us identify cases where we're not.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
