f2071e4f80 Add arbitrary string type to the native object API (#4218)
* Custom strings are very common for optimizations around small objects
  or growth style optimizations, i.e.: grow at 1.57 times vs doubling vs..

  A second common strategy is to cooperate w/ the memory allocator

3f936c5655 More native code gen functionality.
Allow tables to be mapped to native types directly.  For example, a table
representing a vector3 (eg. table Vec3 { x:float; y:float; z:float; }) can
be mapped to a "mathfu::vec3" native type in NativeTables.  This requires
users to provide Pack and UnPack functions that convert between the
Table and native types.  This is done by adding the "native_type" attribute
to the table definition.

To support user-defined flatbuffers::Pack and flatbuffers::UnPack functions,
support a "native_include" markup that will generate a corresponding

Also add an UnPackTo function which allows users to pass in a pointer to
a NativeTable object into which to UnPack the Table.  The existing UnPack
function is now simply:

  NativeTable* UnPack() {
    NativeTable* obj = new NativeTable();
    Table::UnPackTo(obj);
    return obj;
  }

Finally, allow native types to be given a default value as well which are
set in the NativeTable constructor.  This is done by providing a
"native_default" attribute to the member of a table.

7b94eab2b1 Add CodeWriter utility class.
Helps simplify code generation code.  Instead of this:
  code += "inline const " + cpp_qualified_name + " *Get";
  code += name;
  code += "(const void *buf) {\n  return flatbuffers::GetRoot<";
  code += cpp_qualified_name + ">(buf);\n}\n\n";

You do this:
  code.SetValue("NAME", struct_def.name);
  code.SetValue("CPP_NAME", cpp_qualified_name);
  code += "inline const {{CPP_NAME}} *Get{{NAME}}(const void *buf) {";
  code += "  return flatbuffers::GetRoot<{{CPP_NAME}}>(buf);";
  code += "}";
  code += "";

Updated the CPP code generator to use the CodeWriter class.  Most of the
changes in the generated code are white-space changes, esp. around new
lines (since the code generator class automatically appends new lines
when appending a string).  Actual code changes include:

* Renamed "rehasher" to "_rehasher" for consistency with other args in
  Pack function.

* Renamed "union_obj" to "obj: in UnPack function.

* Always do "(void)_o;" to prevent unused variable warning in Create
  function (instead of only doing it if there are no fields) in order
  to avoid two-passes.

* Renamed padding variables from __paddingX to paddingX__.
  "Each name that contains a double underscore (_ _) [...] is reserved
   to the implementation for any use."  C++ standards 17.4.3.1.2.

* Add braces around switch cases.

* Calculate index as a separate statement in EnumName function, eg.
    const size_t index = ...;
    return EnumNamesX()[index];
  vs.
    return EnumNamesX()[...];

* Stored end table offset in variable in Finish() functions, eg.
    const auto end = fbb_.EndTable(start_, ...);
    auto o = flatbuffers::Offset<T>(end);
  vs.
    auto o = flatbuffers::Offset<T>(fbb_.EndTable(start, ...));

* Separate reinterpret_cast calls from function calls in Union
  functions, eg.
    auto ptr = reinterpret_cast<const T *>(obj);
    return ptr->UnPack(resolver);
  vs.
    return reinterpret_cast<const T *>(obj)->UnPack(resolver);

* Removed unecessary (void)(padding__X) no-ops from constructors, eg.
    Test(int16_t a, int8_t b) : ... {
      (void)__padding0;  // <-- Removed this line.
    }

In the idl_gen_cpp.cpp file itself, I refactored some code generation into
new functions: GenParam, GenNativeTable, GenVerifyCall, GenBuilders,
GenUnpackFieldStatement, and GenCreateParam.

cc84240098 Misc idl_gen_cpp cleanup
- Update to be const-correct where possible.
- Consistently pass |code| as pointer instead of non-const-ref.
- No newlines (\n) characters in the middle of code strings.
- Use if-else if-else statements instead of nested ternary operators.
- Ensure all lines end at 80 chars.
- Make utility functions static.

c66683f27f Add ::Set function to Unions to make memory ownership clear.
Unions own the NativeTable* value member because they need to destroy them
when the Union goes out of scope.  Currently, the data is destroyed by calling
delete, which means that the member needs to be allocated with new.  However,
making the allocation the responsibility of the client and the destruction
the responsibility of the Union can lead to potential errors.  Adding a
Set function will ensure that the memory is allocated correctly so that it
can be deleted later.

bc2ec7119b Adds typedefs and functions to help write generic code.
The following changes have been made to the C++ codegen to enable writing generic code
that uses the Table and NativeTable types.

- Adds TableType and NativeTableType typedefs to NativeTable and Table structs.
- Adds GetFullyQualifiedName() to NativeTables if --gen-name-strings is set.
- Adds a static Pack function to Tables that simply calls the global CreateX functions.

See cr/140391505 as an example of improved usage.

641b397f8b Allows structs to be stored directly as member variables.
Introduce a "native_inline" attribute that can be applied on fields that are structs.
This results in NativeTable code generation that sets the struct "inline" rather than
storing it in a pointer.
