This patch changes 'FP Hint' and 'META' so that they directly call the ATM
dissector, instead of using the ERF AAL2 dissector for ATM AAL2 cells (which
was a mistake in the original implementation).

The FP path in the ATM dissector also contains a small patch to optionally skip
the extraction of the 4 byte pseudo-header 'side/length/UUID'. The default
behavior is not changed (a new ATM pseudo-header flag called 'ATM_AAL2_NOPHDR'
is introduced - this solution was suggested and coded by Stephen Donnelly).
