6772308883 buffer: Don't double-negate numeric buffer arg 
Fix #4331

Using double negate forces values into 32bit space. Because of this
Math.ceil needs to be used. Since NaN comparisons are always false, use
that to our advantage to return 0 if it is.

Also added two tests to verify the changes.

13c5db9771 buffer: remove duplicate assertion tests 
Many assertion tests are duplicated in buffer.js. These few could be easily
removed and still have all tests pass.

8bd4590a31 buffer: include encoding value in exception when invalid 
Encoding failures can be somewhat confusing, especially when they are due to
control flow frameworks auto-filling parameters from the previous step output
values to functions (such as toString and write) that developers don't expect
to take an encoding parameter. By outputting the value as part of the message,
should make it easier to track down these sort of bugs.

38542f76a9 buffer: make SlowBuffer inherit from Buffer 
This frees us from manually having to copy over functions to SlowBuffer's
prototype (which has bitten us multiple times in the past).

As an added bonus, the `inspect()` function is now shared between Buffer
and SlowBuffer, removing some duplicate code.

Closes #3228.

Prevents alignment issues when people create a typed array from a buffer.
Unaligned loads or stores are less efficent and (on some architectures) unsafe.
