- add a -loglevel=<level>|<category:level> config option to allow users
to set a global -loglevel and category-specific log levels. LogPrintLevel
messages with a higher severity level than -loglevel will not be printed
in the debug log.
- for now, this config option is debug-only during the migration to
severity-based logging
- update unit and functional tests

...instead of explicitly calling init::{Set,Unset}Globals.
Cool thing about this is that in both the testing and bitcoin-chainstate
codepaths, we no longer need to explicitly unset globals. The
kernel::Context goes out of scope and the globals are unset
"automatically".
Also construct kernel::Context outside of AppInitSanityChecks()
