Release 0.8.2

First release with production-ready multithread mode.

Performance:

• Reduce locking in livesource_send_subscribers
• [threads] Multiple event pools to remove bottleneck
• Use reference counting on sourceline for faster sourcetable creation
• Make packet_incref() and packet_decref() inline functions

Misc:

• Implement exponential backoff for connection retries
• Make sure that RTCM clients on virtual sources see a RTCM position
  packet before getting updates from the new source. This should
  yield better fix stability at base transition
• Correct spelling mistakes by @EdwardBetts in #13
• Update README.md by @Stefal in #12

Fixes:

• [threads] Crash/use-after-free due to potential race conditions at connection start
• [threads] Fix various race conditions
• Handle default string fields in the configuration to avoid crashes at free()
• Several minor memory leaks and use-after-free found by valgrind
• Implement reference counting on sourcetable to avoid use-after-free
• Fix hanging connections at close
• Fixes to received_bytes and sent_bytes counters
• Implement some missing connection timeouts

New Contributors

• @EdwardBetts made their first contribution in #13
• @Stefal made their first contribution in #12

Full Changelog: 0.81...0.82

Release 0.8.1

Main items:

• Fix: don't close a NEAR connection when the current base goes away. Correctly find a new running base instead.
• Fix: don't crash on rare "mapi net" calls due to a race condition on the underlying data structures
• Fix: [multithread] don't crash on a NEAR connection when the client goes away after sending a GGA line but before a base connection is established
