tracker and tracker-miners 2.1.0 releases, fixing a F28 regression in tracker-miners-2.0.5-1.fc28 that caused tracker-extract to respawn in a tight loop and consume high CPU.

tracker 2.1.0:

• build: Make tarballs able to build with meson. Future releases will eventually phase out Autotools
• build: Various meson build fixes
• tests: Many fixes to functional tests
• libtracker-miner: Fixed race conditions that may result in spurious "parent not indexed yet" warnings.
• libtracker-direct: Majorly rewritten
• tracker-store: Streamlined to use a libtracker-direct connection instead of reimplementing most of it.

tracker-miners 2.1.0:

• tests: Many updates and fixes to functional tests
• tracker-extract: Better infrastructure for tests, based on JSON-LD
• tracker-miner-fs: Restart tracker extract from the right domain
• tracker-extract: Persistently avoid files that trigger recoverable errors, to avoid log spamming on restarts.
