+* Purpose:  Convert Reversed MLT (Modulated Lapped Transform) 
+*           Coefficients to Samples
+*
+*     The "Reversed MLT" is an overlapped block transform which uses
+*     even symmetry * on the left, odd symmetry on the right and a
+*     Type IV DCT as the block transform.  * It is thus similar to a
+*     MLT which uses odd symmetry on the left, even symmetry * on the
+*     right and a Type IV DST as the block transform.  In fact, it is
+*     equivalent * to reversing the order of the samples, performing
+*     an MLT and then negating all * the even-numbered coefficients.

+ ** UAC tests.
+ **
+ ** This file performs various tests for UAC transactions. Each test will have
+ ** a different Via branch param so that message receiver module and 
+ ** transaction user module can identify which test is being carried out.
+ **
+ ** TEST1_BRANCH_ID
+ **	Perform basic retransmission and timeout test. Message receiver will
+ **	verify that retransmission is received at correct time.
+ **     This test verifies the following requirements:
+ **	    - retransmit timer doubles for INVITE
+ **	    - retransmit timer doubles and caps off for non-INVITE
+ **	    - retransmit timer timer is precise
+ **	    - correct timeout and retransmission count
+ **     Requirements not tested:
+ **	    - retransmit timer only starts after resolving has completed.
+ **
+ ** TEST2_BRANCH_ID
+ **	Test scenario where resolver is unable to resolve destination host.
+ **
+ ** TEST3_BRANCH_ID
+ **	Test scenario where transaction is terminated while resolver is still
+ **	running.
+ **
+ ** TEST4_BRANCH_ID
+ **	Test scenario where transport failed after several retransmissions.
+ **
+ ** TEST5_BRANCH_ID
+ **	Test scenario where transaction is terminated by user after several
+ **	retransmissions.
+ **
+ ** TEST6_BRANCH_ID
+ **	Test successfull non-INVITE transaction.
+ **     It tests the following requirements:
+ **	    - transaction correctly moves to COMPLETED state.
+ **	    - retransmission must cease.
+ **	    - tx_data must be maintained until state is terminated.
+ **
+ ** TEST7_BRANCH_ID
+ **	Test successfull non-INVITE transaction, with provisional response.
+ **
+ ** TEST8_BRANCH_ID
+ **	Test failed INVITE transaction (e.g. ACK must be received)
+ **
+ ** TEST9_BRANCH_ID
+ **	Test failed INVITE transaction with provisional response.
