Often the messages contains parameters (%d, %s, ...) or are split into multiple lines to appease the ancient 80 columns god.
These make it harder to grep.
Having the /right/ name makes it easier to get to the right place.

The two problems this change solves are very simple:
- There are needlessly about a dozen different ways used to add the function name into the panic message.
  This change unifies it.
- All too often the name is wrong.
  This change gets it right every time without any manual and error-prone effort of somebody, who adds a use of PANIC().

I do not understand, what the problem is.
There are bugs and cumbersome code.
This simple changes solves it.
