Use fully-qualified names for linking, too
...
Using libraries leaves behind a library link reference in the binary
which the linker must later resolve. These link references were still
being generated by name and not by fully-qualified name. This would
lead to a link-time collision between two libraries having the same
name but in different source units.
This change changes linker symbols over to fully-qualified names,
which resolves that issue. This does potentially introduce a new
problem, which is that linker symbols appear to be limited to 36
characters and are truncated. Storing paths extends the average
symbol size, and it would be great if truncation was from the tail
rather than the head.

Unimplemented features moved to their own exception
InternalCompilerError is an exception that really should be reserved for
actual internal errors of the compiler. Unimplemented features can now
use either solUnimplemented( ) or, if it should be conditional, then
solUnimplementedAssert( ).
* Revert some unimplemented exceptions, add handlers
The jsonCompiler and CommandLineInterface needed handlers for the
new UnimplementedFeatureException, and some cases I had moved on to
the new exception were better treated as real internal compiler
errors.
* Standardize on "Unimplemented feature" message
