TGC Digitization: Implementation of signal propagation time between the sensor edge and ASD (sweep from MC20)
This is a manual sweep of !46540 (merged) due to some obscure (5 year old!) conflicts.
Add the new db system to fix the missing timing calculation at the TGC_Digitization stage between the sensor edge and the ASD. TGC_Digitization retrive the information of the distance between the sensor edge and ASD from the condition db. Condition algorithm (TGCDigitASDposDbAlg) and condition object (TGCDigitASDposData) have been added to manage the condition data in AthenaMT. TGC_Digitization has been modified to use the new TGCDigitASDposDbAlg and TGCDigitASDposData and added the method to calculate of signal propagation time from sensor edge to the ASD. The compilation is fine, no errors or warnings. The test has been done locally.
