Use native Math functions in the custom log2 function 
It is quite confusing that the custom function is called `log2` while it
actually returns the ceiling value and handles zero and negative values
differently than the native function.

To resolve this, we add a comment that explains these differences and
make the function use the native `Math` functions internally instead of
using our own custom logic. To verify that the function does what we
expect, we add unit tests.

All browsers except for IE support `Math.log2` for quite a long time
already (see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/log2).
For IE, we use the core-js polyfill.

According to the microbenchmark at https://jsperf.com/log2-pdfjs/1,
using the native functions should also be faster, in my testing almost
six times as fast.

6b1eda3e12 Move StatTimer from src/shared/util.js to src/display/dom_utils.js 
Since the `StatTimer` is not used in the worker, duplicating this code on both the main and worker sides seem completely unnecessary.

d5174cd826 Remove the requestAnimationFrame polyfill 
According to https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame#Browser_compatibility and https://caniuse.com/#feat=requestanimationframe, the browsers we intend to support with PDF.js version 2.0 should all have native `requestAnimationFrame` support.

Note that the reason for indiscriminately polyfilling `requestAnimationFrame` in iOS, see PR 4961, was apparently because of a bug in iOS 6.
However, according to [Wikipedia](https://en.wikipedia.org/wiki/IOS_version_history#iOS_8): "Support for iOS 8 ended in 2017.", hence the lowest version currently supported is iOS 9.

745cb73c65 Remove PDFJS.disableRange/PDFJS.disableStream code for now unsupported browsers in src/shared/compatibility.js 
We're currently disabling range requests and streaming for a number of configurations. A couple of those will no longer be supported (with PDF.js version 2.0), hence we ought to be able to clean up the compatibility code slightly.

742ed3d1c9 Remove __pdfjsdev_webpack__, use webpack options 
`__pdfjsdev_webpack__` was used to skip evaluating part of an AST,
in order to not mangle some `require` symbols.
This commit removes `__pdfjsdev_webpack__`, and:

- Uses `__non_webpack_require__` when one wants the output to
  contain `require` instead of `__webpack_require__`.
- Adds options to the webpack config to prevent "polyfills" for
  some Node.js-specific APIs to be added.
- Use `// eslint-disable-next-line no-undef` instead of `/* globals ... */`
  for variables that are not meant to be used globally.

0c13d0ff46 Adds Streams API in getTextContent to stream data. 
This patch adds Streams API support in getTextContent
so that we can stream data in chunks instead of fetching
whole data from worker thread to main thread. This patch
supports Streams API without changing the core functionality
of getTextContent.

Enqueue textContent directly at getTextContent in partialEvaluator.

Adds desiredSize and ready property in streamSink.
