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)
When accessing a union field, we should return the same object type
as was given to the method, i.e. the parameter should have a generic
type for any Table-derived type. This way, we do not need to make
superfluous casts (which also reduce type safety) like
var myUnionType = (MyUnionType)buff.GetUnionField(new MyUnionType());
when we can do just
var myUnionType = buff.GetUnionField(new MyUnionType());

Also made proper namespacing work for enums.
You can now say namespace.MyTable as the type when declaring
a field that refers to a type in a different namespace.
Previously, it would work just referring to MyTable, however
with the recent commit fixing namespaced types this now
is ambiguous.

Tested: on Linux.
In C#, plain field accessors should not be nonparametric methods
but should be standard property getters.
The accessor methods with parameters were renamed to `GetXxx`
because a method cannot be named identically to a property.
Also, `ByteBuffer.Position`, `FlatBufferBuilder.Offset` and
`FlatBufferBuilder.DataBuffer` are now properties instead
of nonparametric accessor methods, for more idiomatic C# style.
This is a breaking change, all client C# code accessing these
fields needs to be changed (i.e. remove those `()` or add the
`Get` prefix).

non-const accessors and mutation functions for existing fields generated
from --gen-mutable.

Bug: 15777024
If an IDL file uses DOS-style EOLs (CR+LF), line comments need to
ignore the second linebreak character, otherwise, as is currently
the case, the parsed documentation comment includes a trailing `\r`
character, which is then output verbatim into the output source
code by flatc.

Enums should not be (badly) emulated with classes in C# but should
use native C# enums instead. Java implementation made an explicit
choice not to use the (more complex) Java enums, but C# enums are
just light-weight syntactic coating over integral types.
Fixes issue #171.

- Add parse handling of .proto struct and field doc comments (enums and
their values were already handled)
- Add FBS generation handling of doc comments for structs, their
fields, enums, and their values (requires linking idl_gen_general in
the test binary build)
- Tested using test.proto|golden with doc comments added. Xcode run of
flattest passes.

Tested by regenerating all tests/ generated sources; note that only
Monster.java changes. Ran flattests as well.

(Java doesn't support unsigned types).
ubyte/ushort return as int
uint returns as long
(all with correct masking)
ulong still returns as long, as before.

There is a bug in creating a C# table when it includes a field of type 'BOOL'. The problem is that the generate C# code is as follows:
"bool SampleValue = 0;"
This will fail to compile, because in C# this fails, it needs to be generated as:
"bool SampleValue = false;"
The error is in line ~510

FlatBuffer schema files can now optionally specify a hash attribute that
will allow someone writing json files to enter a string to be hashed
rather than a specific value. The hashing algorithm to use is specified
by the schema.
Currently the only algorithms are fnv1 and fnv1a. There are 32 bit and
64 variatns for each. Additionally, a hashing command line tool was
added so that you can see what a string will hash to without needing to
inspect the flatbuffer binary blob.

getRootAs..() function now has a second implementation that
accepts an existing object to allow object reuse, much like
all other methods that refer to objects.

If the schema didn't contain a namespace, paths would contain a
leading /, causing files not to be written.

Also added strict_json option to the parser, which in
addition controls if field names without quotes are allowed.
