org.apache.http.legacy is built with java_sdk_library

The runtime library, stubs library and droiddoc are all abstracted into
the java_sdk_library module definition.

Note: LogConfigurationException has getCause() method inherited from its
parent class RuntimeException. This is a correct fix because doclava
adds overridden methods into the API signature. (see
frameworks/base/api/current.txt and look for getCause() for existing
cases)
