  Correct documentation of get_modules message

The -T option has not been working for a long time.

The table used during translation of forms to types used to be a
dictionary of the type info (-type(), -opaque(), and -record()) for
all modules. Now it is reduced to the modules that are needed to
handle references to types in other modules.

The PLT:s type info is still kept on the heap.

  dialyzer: Compact 'file' annotations in Core code
  dialyzer: Try to reduce memory usage
  dialyzer: Use less memory when translating contracts
  dialyzer: Use maps instaed of dict
  dialyzer: Use maps instead of dict for module contracts map
  dialyzer: Compress a few more ETS tables
  dialyzer: Optimize memory consumption
  dialyzer: Reduce memory consumption during 'remote' phase
  dialyzer: Update code for finding parallelism
  compiler: Do not spawn process when dialyzing
  dialyzer: Reduce ETS usage during the typesig phase
  dialyzer: Optimize graph condensation
  dialyzer: Do not send full PLTs as messages

The translation from forms to types is done in a separate process
in an attempt to reduce peak memory usage.

Expect further optimizations as it is probably not feasible
in the long run to keep all type information on the heap.

The mini PLT is extended to hold all data of the full PLT, and the
full PLT is restored when needed (for storing the PLT on file).
