Replace sentinel NULL with nullptr, guaranteed to be correctly expanded.
NULL may be defined as plain 0 in C++; which may lead to undefined upper
bits passed in variadic function arguments, causing crashes.

- CddaSongLoader destructor waits for thread to end.
- Added flag to interrupt LoadSongsFromCdda
- Only start song loading if not already running
- Removed (now obsolete) mutex
QUrl interprets a single number as an ip address, so the track URL cdda://1
would become cdda://0.0.0.1. A previous fix addresses this issue by adding an
extra character "a" to the affected URLs then removing the last instance of the
character upon usage. However, this didn't apply when a path was present
(cdda:///dev/sr0/1), but would still attempt to reverse the change later
(cdd:///dev/sr0/1).
This change applies the fix-up to all cdda urls and moves the conversion
utilities to a single location.

GError messages contain non-ascii characters. This normally just produces some garbage when we use the default QString contructor that assumes ASCII for logging. However, when a message includes the right double quote, UTF-8 sequence 0xE2 0x80 0x9D, the final byte is OSC. VT100 expects a command sequence to follow and stops echoing output until it sees ST or BEL character, which may never come. Thus, the console output is halted.
This change uses QString::fromLocal8Bit instead of depending on the default constructor. About half of the sites in the codebase had already been converted.
One side effect is that log messages are quoted. There are additional options to control this, but those were only introduced in Qt 5.4.
