Include C# codegen in flatc and .NET FlatBuffer access via the
FlatBufferBuilder class

Tested: on Windows.

Change-Id: If5228a8df60a10e0751b245c6c64530264ea2d8a

Added FLATBUFFERS_BUILD_TESTS option which can be used to disable
the build of flatbuffers tests and samples.

Tested:
Verified tests and samples are no longer built on Linux when
FLATBUFFERS_BUILD_TESTS=OFF.

Readonly ByteBuffers and Direct ByteBuffers don't have a backing
array, and thus can't be used for writing FlatBuffers (though
they are fine for reading).

Since part of it is based on the filename, which may contain
characters that are not legal identifiers.

This would cause double definition linker errors when included in
multiple compilation units.

Previously they were only generated for the root_type, making it
impossible to use the other types in the file as the root of a buffer.

Theoretically, an attacker could construct a FlatBuffer with the
sole purpose of making verification really expensive, essentially
DOS-ing a server that uses verification on FlatBuffers. This adds
a max table depth and max table amount at which point the
verifier declares the buffer malformed.

This happens when the schema is parsed, to avoid compile time errors
later, which would be harder to understand.

Tested that a command line like: ./flatc -j -o foo/bar/baz tests/monster_test.fbs
generates files in foo/bar/baz/MyGame/Example/*.java which previously didn't exist.

Windows code was previously tested but has been moved, so needs to be tested again.

Previously, it would ignore the fact that the type comes from a
different namespace. Now they are pre-declared in their own namespace,
and referenced with a qualified name if necessary.
