Adds a `.indexOf` method to `Buffer`, which borrows semantics from both `Array.prototype.indexOf` and `String.prototype.indexOf`. `Buffer.prototype.indexOf` can be invoked with a Buffer, a string or a number as the needle. If the needle a Buffer or string, it will find the first occurrence of this sequence of bytes. If the needle is a number, it will find the first occurrence of this byte. Reviewed-by: Sam Rijs <srijs@airpost.net> Fixes: #95 PR-URL: #160
Expanding and reusing code by Sam Rijs in commit 4dedc09 to also add a `.lastIndexOf` method to `Buffer`. `Buffer.prototype.lastIndexOf` takes the same arguments as its predecessor and uses a divide-and-conquer method to find the last occurrence of the sequence of byte.

I have no opinion on the subject but from what I'm seeing is that #561 will supersede this PR. However, it has been indicated that there will be no I'm unsure with how to proceed with this specific PR, as only one commit seems to be prevalent now. @algesten? |

V8 will increase the maximum TypedArray size in https://crrev.com/c/4872536; this CL adapts the tests to allow for that. Tests that hard-code smaller sizes or are already tested in V8 are removed; one test is adapted to not rely on a specific limit. # Conflicts: # test/parallel/test-buffer-alloc.js # test/parallel/test-buffer-tostring-rangeerror.js

Expanded on @srijs code to add a
Buffer.prototype.lastIndexOf. I used a strategy of divide/conquer, but since I'm a total c++ idiot, I have no idea whether there is a better way (some reverse memcmp variant?). Also I rebased both srijs and these commits against v0.12 hoping it would make it out sooner :)
