bdd739e91c base64: Only run benchmark when "-t" is specified. 
As the test is run during fate and the benchmark is useless for fate
this very slightly speeds up fate. Its also consistent with the other
tests.

d086c1203c Add coverage exclusions for test code. 
For some of the code e.g. doing timing measurements there is no
real point in running regression testing on it, thus it should
not be counted against coverage.

ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
