org.checkerframework.framework should be independent of org.checkerframework.common

The framework package should be independent of the common package. However, there are currently imports of the latter into the former, breaking the intended separation between the two packages.
This issue can be resolved by either breaking the dependency (preferred), moving something from the framework to common (also good), or moving the dependency into the framework package (not good).

For an under-approximation, in checker-framework/framework/src/org/checkerframework/framework run:
grep -R "import org.checkerframework.common" .
to get something like:

./type/GeneralAnnotatedTypeFactory.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./type/AnnotatedTypeFactory.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./type/AnnotatedTypeFactory.java:import org.checkerframework.common.reflection.DefaultReflectionResolver;
./type/AnnotatedTypeFactory.java:import org.checkerframework.common.reflection.MethodValAnnotatedTypeFactory;
./type/AnnotatedTypeFactory.java:import org.checkerframework.common.reflection.MethodValChecker;
./type/AnnotatedTypeFactory.java:import org.checkerframework.common.reflection.ReflectionResolver;
./type/AnnotationClassLoader.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./type/GenericAnnotatedTypeFactory.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./type/DefaultTypeHierarchy.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./util/DependentTypes.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./util/PurityAnnotatedTypeFactory.java:import org.checkerframework.common.basetype.BaseAnnotatedTypeFactory;
./util/PurityAnnotatedTypeFactory.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./util/PurityChecker.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./source/SourceChecker.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./flow/CFAbstractAnalysis.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./flow/CFCFGBuilder.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./flow/CFAbstractTransfer.java:import org.checkerframework.common.basetype.BaseTypeChecker;
./flow/CFAnalysis.java:import org.checkerframework.common.basetype.BaseTypeChecker;

Start in checker-framework/framework/src/org/checkerframework/framework and run the issue's grep command to enumerate remaining imports. Inspect the listed classes, especially under type, util, source, and flow, to trace each dependency and choose a separation approach. Done means framework no longer imports org.checkerframework.common; rerun grep to verify.
