Fix for the issue #4744: Ambiguous side-effect execution on vector_downward::make_space() method.
C++ does not impose evaluation order on the two expressions on the right side of the assignment, so compiler can freely decide. As ensure_space() method can change the value of "cur_" variable, the result of the subtraction may be different depending on the evaluation order, which is ambiguous in C++.
In order to make this code deterministic and correct, cur_ must be evaluated after ensure_space() is called.

* Python: handle bool table fields properly.

* Small refactor.

* Use snake_case instead of camelCase. Use auto.

Removing for required fields improves compiler warnings
but doesn't impact any running code.

Const does not make sense here, and compiler actually throws warning
(error with -Werror) when you would try to compile it.

* Convert to unsigned char before applying bit shift operator

* convert to const unsigned char inline

* convert to unsigned char inline

to be able to convert to json size prefixed buffers.

An assert in flexbuffers was bit-shifting a 64-bit number by
64 bits, which throws up warnings in some automated tools.

The same assert also checks to see if the number of bytes
being shifted is 8.  Swapped the order, so that the bitshift
only occurs if the number of bits being shifted is not 64.

Should be the same behavior, but plays nicer with diagnostic
tools.

* Added '--oneof-union' option.

Used with the .proto -> .fbs converter, will translate protobuff oneofs to flatbuffer unions.
Updated proto test to check both methods of converting oneofs.
