Release v3.19.0

This release adds enhancements, bug fixes and test improvements.

Enhancements:
 - Download manifest deltas when provided by the server to have smaller updates
 - Swupd can verify a list of bundles instead of verifying the full system
 - Improve error messages on swupd network connection errors
 - Return meaningful and consistent exit codes on swupd errors
 - Add configurable download retries (--max-retries and --retry-delay)
 - Add bytes transferred in telemetry reports and inform this to the user on updates
 - Start tracking manually installed bundles so we can use that info in the future

Bug Fixes:
 - Don't remove files under /usr/src on verify --fix --picky
 - Don't force bootloader execution if the bootloader binary isn't present
 - Don't follow relative symlinks when installing new files
 - Use timestamp from installed system when adjusting the system time

Tests
 - Add unit tests to functions hard to test using functional tests
