* commit '9e6afdf96f98259f89aad66367954a247b3e7817':
  Add two codegen parameters to nano.

enum_style = c | java: 'c' to put the enum member int constants
at the parent scope; 'java' to create uninstantiatable shell
classes at the parent scope and put the int constants inside.

optional_field_style = default | accessors: 'default' to create
one public mutable field per optional proto field; 'accessors'
to encapsulate the generated fields behind get, set, has and
clear accessors.

This CL only contains parsing code for these two parameters.

  Fix outer classname for javamicro/javanano.

- File class name is defined as the java_outer_classname option value
  or the file name ToCamelCase; never the single message's ClassName.
- File-scope enums are translated to constants in the file class,
  regardless of java_multiple_files.
- If java_multiple_files=true, and file's class name equals a message's
  class name, no error. This is done by detecting that the outer class
  is not needed and skipping the outer class codegen and clash checks.
  Note: there is a disparity between java[lite] and the previous
  java{micr|nan}o: when generating code for a single-message proto, the
  outer class is omitted by java{micr|nan}o if the file does not have
  java_outer_classname. This change makes java{micr|nan}o align with
  java[lite] codegen and create the outer class, but will print some
  info to warn of potential change of code.
- Also fixed the "is_own_file" detection and made all parseX() methods
  static. Previously, all messages in a java_multiple_files=true file
  are (incorrectly) considered to be in their own files, including
  nested messages, causing them to become inner classes (instance-
  bound) and forcing the parseX() methods to lose the static modifier.
- This change supersedes c/60164 and c/60086, which causes javanano to
  put enum values into enum shell classes if java_multiple_files=true.
  We now always use the parent class to host the enum values. A future
  change will add a command line option to provide more flexibility.
- Elaborated in java/README.txt.

* commit '87c8e31b8c0baa78f979863a9ed10654a1cdca1f':
  Fixed packed repeated serialization.

Remove buggy memoization. Memoization also is too fragile for the api
because the repeated field is public.

  Per-file java_multiple_files flag.

Depends on Ia532647fe8811d39230a23ba3671685b0388cbe0

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.
