a62c7bd54c Fix use of undeclared core debug category symbols

symbols GST_CAT_*, but those are not declared in any

to declare and use those, but that's just not right at
all, and it won't work on Windows with MSVC. Instead look
up the categories via the API.

f31240a765 encoding-profile: Don't use preset_name string after free 
When we run the loop for another time and do not have a preset name, we would
try to print the preset name of a previous iteration that is already freed.

Also move some other variables into the block where they are actually used
to prevent similar mistakes in the future.

conversion test and an extra test case for passthrough operations.

0bd3f818bb audio-converter: code cleanup 
Rename samples to num_samples, since we also have samples in chain, but that is
the data pointer. Always use gzize for num_samples. Make the log output a bit
more homogenous.
