objint: Implement int.from_bytes() class method and .to_bytes() method. These two are apprerently the most concise and efficient way to convert int to/from bytes in Python. The alternatives are struct and array modules, but methods using them are more verbose in Python code and less efficient in memory/cycles. 2014-04-08 21:40:58 +00:00			`print((10).to_bytes(1, "little"))`

py: Support conversion of bignum to bytes. This gets int.to_bytes working for bignum, and also struct.pack with 'q' and 'Q' args on 32-bit machines. Addresses issue #1155. 2015-04-25 22:16:39 +00:00			`print((2**64).to_bytes(9, "little"))`
