buffer: do not always use defaults
The Buffer#(read|write)U?Int(B|L)E functions should not use a default
value. This is very likely a bug and it was never documented that
way.

Besides that this also improves the tests by adding more tests and by
refactoring them to less code lines.

errors: validate input arguments
This makes sure the input arguments get validated so implementation
errors will be caught early. It also improves a couple of error
messages by providing more detailed information and fixes errors
detected by the new functionality. Besides that a error type got
simplified and tests got refactored.

If none is provided, use zero as a default offset for all read/write
operations on the buffer.

buffer: refactor all read/write functions
There are a lot of changes in this commit:

1) Remove the `noAssert` argument from all read and write functions.
2) Improve the performance of all read floating point functions
   significantly. This is done by switching to TypedArrays as the
   write floating point write functions.
3) No implicit type coercion for offset and byteLength anymore.
4) Adds a lot of tests.
5) Moves the read and write functions to the internal buffer file
   to split the files in smaller chunks.
6) Reworked a lot of existing tests.
7) Improve the performane of all all read write functions by using
   a faster input validation and by improving function logic.
8) Significantly improved the performance of all read int functions.
   This is done by using a implementation without a loop.
9) Improved error handling.
10) Rename test file to use the correct subsystem.

8172f4547e buffer: move setupBufferJS to internal
Stashing it away in internal/buffer so that it can't be used in
userland, but can still be used in internals.

buffer: allow Uint8Array input to methods
Allow all methods on `buffer` and `Buffer` to take `Uint8Array`
arguments where it makes sense. On the native side, there is
effectively no difference, and as a bonus the `isUint8Array`
check is faster than `instanceof Buffer`.

e8eaaa7724 buffer: add buffer.transcode
Add buffer.transcode(source, from, to) method. Primarily uses ICU
to transcode a buffer's content from one of Node.js' supported
encodings to another.

Originally part of a proposal to add a new unicode module. Decided
to refactor the approach towrds individual PRs without a new module.
