Node.js v7.2.1 Release Brief

This routine patch release un-deprecates calling Buffer without the new keyword, and also includes more useful stacktraces for promise warnings when --trace-warnings is enabled.

As with all releases within major version lines, minor and patch upgrades should be drop-in replacements for previous versions.

    buffer: convert offset & length to int properly

    As per ecma-262 2015's #sec-%typedarray%-buffer-byteoffset-length,
    `offset` would be an integer, not a 32 bit unsigned integer. Also,
    `length` would be an integer with the maximum value of 2^53 - 1, not a
    32 bit unsigned integer.

    This would be a problem because, if we create a buffer from an
    arraybuffer, from an offset which is greater than 2^32, it would be
    actually pointing to a different location in arraybuffer. For example,
    if we use 2^40 as offset, then the actual value used will be 0,
    because `byteOffset >>>= 0` will convert `byteOffset` to a 32 bit
    unsigned int, which is based on 2^32 modulo.

    This is a redo, as the ca37fa527f174b547893817fe8c67a3befa02317 broke
    CI.
