Prior to 119354f we specifically handled passing a zero length string to write on a buffer, restore that functionality.
This also templatizes the Buffer::*Slice functions, and the template function probably cannot be safely used outside of Node. However, it also SHOULD not be used outside of Node, so this is arguably a feature as well as a caveat.
Speed up ASCII character scanning and conversion by 25% to 30% by scanning and converting whole words instead of individual bytes.
Consider the following example:
console.log(Buffer('ú').toString('ascii'));
Before this commit, the contents of the buffer was used as-is and hence it
prints 'ú'.
Now, it prints 'C:'. Perhaps not much of an improvement but it conforms to what
the documentation says it does: strip off the high bits.
Fixes #4371.
It was returning true for typed arrays. Check that the object was instantiated with the Buffer constructor.

Move the implementation to C++ land. This is similar to commit 3f65916 but this time for the write() function and the Buffer(s, 'hex') constructor. Speeds up the benchmark below about 24x (2.6s vs 1:02m). var s = 'f'; for (var i = 0; i < 26; ++i) s += s; // 64 MB Buffer(s, 'hex');
Move the implementation to C++ land. The old JS implementation used
string concatenation, was dog slow and consumed copious amounts of
memory for large buffers. Example:
var buf = Buffer(0x1000000); // 16 MB
buf.toString('hex') // Used 3+ GB of memory.
The new implementation operates in O(n) time and space.
Fixes #4700.
If the end argument is omitted or not a number, make it default to the end of the buffer, not zero. Ideally, it should not matter what it defaults to because the JS shim in lib/buffer.js should handle that but there are still several places in node.js core that secrete SlowBuffers, hence Buffer::Copy() gets called without going through Buffer.prototype.copy() first.
