repo wide : Name SDRangel-owned threads for debugging

Assign descriptive names to SDRangel threads so thread activity can be
identified when investigating multi-threaded behavior, including crashes,
leaks, and synchronization issues in debuggers and others tools.

Use compact names to fit platform thread-name limits (14 chars) while
retaining the component and thread role where possible.
