Per-file java_multiple_files flag.

Imported source files may have different values for the 'java_multiple_files'
option to the main source file's. Whether the fully qualified Java name of an
entity should include the outer class name depends on the flag value in the
file defining the referenced entity, not the main file. This CL loads the
flag values from the main and all transitively imported files into the params,
and generates the fully qualified Java names accordingly.

If the generator option 'java_multiple_files' is set, its value overrides any
in-file values in all source/imported files. This is because this generator
option is typically used on either none or all source files.
