added "native_custom_alloc" attribute to tables/structs, eg.

table parent_table( native_custom_alloc:"custom_alloc_name" ) {
...
}

with a custom allocator defined as

template <typename T> class custom_alloc_name : public std::allocator<T> {
public:

 typedef T*       pointer;

 template <class U>
 struct rebind {
  typedef custom_alloc_name<U> other;
 };

 pointer allocate(const std::size_t n) {
      return ....;
 }

 void deallocate(T* ptr, std::size_t n) {
    ...
 }

 custom_alloc_name() throw() {}
 template <class U> custom_alloc_name(const custom_alloc_name<U>&) throw() {}
};
};

Use a combination of travis and twine to publish to PyPI. New
publications will be made:

* When `master` is updated. This will trigger the publication of a
  the Python artifact versioned an iso-compliant build datetime. In this
  way, the cutting edge version will always be available via PyPI.
* When a new git tag is pushed. Tag pushes trigger the publication of
  a python artifact with the same version as the git tag, with the
  leading `v` stripped if present (`v1.2.3` becomes `1.2.3`).

Publications rely on Travis having a PYPI_PASSWORD environment set in
the project settings. See the Travis CI documentation for information on
[setting environment variables which containing sensitive data][1]. Make
extra sure the "Display value in build log" switch is OFF.

In addition to setting the previously mentioned `PYPI_PASSWORD`
environment variable, the owner of the PyPI `flatbuffers` repository
should, after merging this commit into master, add his own commit to
change `mikeholler` in `.travis/deploy-python.sh` to his username. It's
also recommended that the owner of `flatbuffers` use a separate account
in the unlikely event that the environment variable somehow becomes
compromised. Again, this is very unlikely, since the environment
variable is only set for "safe" builds approved by maintainers (not on
random pull requests).

`Equipment` is a union, not an enum.

Also added a test.

Tested on: Linux.

Each target that will be installed will also generate a target that will be
included by CMake config file.

* Remove copy constructor to make flatbuffers struct trivially copyable + add tests.

* Add support non c++11 compliant compilers.

* Fix std::trivially_copyiable test for non-C++11 compliant compilers.

* Fix trivially_copyable not part of glibc < 5 even with c++11 switch enabled.

VerifyObject called VerifyTableStart() but not EndTable(). This made Verifier::VerifyComplexity() increase depth_ with each table, not with the depth of tables.

In some debug environments using vector[i] does bounds checking even
though the standard specifies that it should not. Using
*(vector.begin()) sidesteps this though, giving the same result without
the bounds checking.

* add _Nullable Support for C++ interface

* generate @Nullable for Java generated code

Report a build failure when any Android build fails.

The travis script was only failing if the last Android build fails.
This changes the script to report a failure if any of the Android
projects fail to build.

f2b3705c caused Android builds
to fail.  This switches limit constants to use limits templates in
stl_emulation.h.

Use flatbuffer unique_ptr instead of std's.

Stlport does not have std unique_ptr, so using the one provided by
flatbuffers.
Also fixing a problem with the flatbuffer unique_ptr, and a test.

This CL also introduces the following changes to allow the generation of the
Go library for flatbuffers:

- add support for --gen-onefile for Go to simplify the build rule (mapping each
  input .fbs to a single separate .go file)

- add a new --go-import flag to override the default import line (currently
  github.com/google/flatbuffers/go)

- add new go_library in BUILD for flatbuffer (for files in flatbuffers/go)
