Force the symbol library links whenever the symbol library table has been
modified. This will use the cache as a fallback when a library has been
removed that contains links in the schematic rather than display.
Fix the SCH_COMPONENT symbol resolver when falling back to the cache. The
resolver was using the LIB_ID ':' notation which was failing. Replacing
':' with '_' fixed this issue. This was also an issue when generating the
symbol message panel information.
Convert wxLogDebug to wxLogTrace in symbol resolver code path. Add new
trace type KICAD_SYM_RESOLVE.

This is done to avoid a big chunk of conditionally-compiled code
in the middle of the event function.
Also separates the zoom logic from the WX_VIEW_CONTROLS object
and isolates it in a separate class behind a clearer interface.
Add some simple tests for sane steps on GTK+3-sized scroll
steps.
Replace all instances of wxLogDebug with wxLogTrace in the common and
kicad folders to prevent unwanted debugging output.
Add new trace flags for locale and screen object tracing.
The usual smattering of code policy fixes.
