* ran generate_code.sh
* Use a hash table to index existing vtables
This allows for quick deduplication even in situations where there
might be thousands of vtables due to 'combinatoric explosion'.
This fixes issue #5301.
* Refactor 0-offset trimming
* Improve deduplication benchmark
The routine now generates a set of realistic logical layouts and
uses a timer function that randomly picks a layout for each iteration.
The benchmark runs in batches of # of logical layouts = 1, 10, 100, 1000.
(Note that due to alignment, the actual number of vtables is usually slightly
higher.)

This is something the format supports, but none of the builders
were doing. Can save 10-20% on FlatBuffer binary size!
Also fixed the Go tests.

Tested: on Linux.
There was no way to pass an already-encoded string to
`builder.CreateString` in Python 2.7:
- Passing a `bytearray` raised a TypeError because `bytearray` was not
recognized as an instance of `compat.binary_type`.
- Passing a utf-8 encoded `str` would cause the string to be
double-encoded, because `compat.string_types = (basestring,)` and
`basestring` is the base class of `str` and `unicode`, so the logic
would never reach the `elif isinstance(s, compat.binary_type)` case.
- Converting a utf-8 encoded bytearray to `bytes` like
`builder.CreateString(bytes(encoded_string))` does not work because
in Python 2.7, bytes is just an alias for `str` so it behaves as
above.
This change allows either `bytes` or `bytearray` as an already-encoded
string to be passed to `CreateString` in versions of Python that support
`bytearray`, and falls back to `str` in older versions.
In Python 2, it restricts unencoded string types to `unicode`, so `str`
can be used as an encoded, binary representaiton.
Adding an API reference for the supported languages.
General docs cleanup, including a new `tutorial` section that
supports all of the supported languages.
Added samples for each supported language to mirror the new
tutorial page.
Cleaned up all the links by making them `@ref` style links,
instead of referencing the names of the generated `.html` files.
Removed all generated files that were unnecessarily committed.
Also fixed the C# tests (two were failing due to a missing file).
Bug: b/25801305
Tested: Tested all samples on Ubuntu, Mac, and Android. Docs were
generated using doxygen and viewed on Chrome.

When passing a unicode string to builder.CreateString, the
default encoding assumed all characters can be encoded
using ascii. Added a fix so a user can specify the
encoding and how to handle errors when creating strings.
+ Add state to the Builder object to track if we are inside a table,
and if we are finished building the buffer.
+ Use this data to check that a buffer is being built correctly.
+ Raise an exception if a buffer is not being built correctly.
+ Test that the exceptions happen as expected.
Based on d236dea.
Implement code generation and self-contained runtime library for Python.
The test suite verifies:
- Correctness of generated Python code by comparing output to that of
the other language ports.
- The exact bytes in the Builder buffer during many scenarios.
- Vtable deduplication correctness.
- Edge cases for table construction, via a fuzzer derived from the Go
implementation.
- All code is simultaneously valid in Python 2.6, 2.7, and 3.4.
The test suite includes benchmarks for:
- Building 'gold' data.
- Parsing 'gold' data.
- Deduplicating vtables.
All tests pass on this author's system for the following Python
implementations:
- CPython 2.6.7
- CPython 2.7.8
- CPython 3.4.2
- PyPy 2.5.0 (CPython 2.7.8 compatible)
