There's no longer any need to make the two arguments have the same
signedness, so we can drop the "u" suffix on literal integer
arguments.

Before this CL, the IntelligibilityEnhancer introduced a processing delay to the lower band, without compensating for it in the higher bands. This CL corrects this.

Label less chunks as speech, adapt slower and be more conservative with the maximum gain it can apply.

This reduces its complexity by a factor of 2.7x total.
The mean error introduced by this is in the 6 different noise scenarios and 6 different speech signals tested is below -52dB.

Although the algorithm should generate the optimal gains, these limits are in place so that it doesn't go bananas in extreme noise situations or if there are some errors on the noise estimate. The limits were chosen as the extreme values from recordings with -3dB SNR, which is the minimum where the POLQA metric increases when processed.

The render signal that reaches the IE is already normalized and compressed by an AGC on the far-end capture processing. Because the noise estimation is done before the AGC compression, we need to compensate for this gain in the IE to be able to compare these 2 powers.

Reason for revert:
Because of down-stream dependencies, this CL needs to be reverted.
The dependencies will be resolved and then the CL will be relanded.

This CL caused a google3 breakage due to dependencies in Google3.
I will fix that, and reland.

This makes the addaptation of the IntelligibilityEnhancer slower, which makes it take more time to kick in or when the background noise changes drastically. But on the other hand, it reduces the risk of clipping and makes the changing in coloring less noticeable.

VS 2015 has a new or louder warning about 32-bit shifts that are then
assigned to a 64-bit target. This type of code triggers it:
int64_t size = 1 << shift_amount;
Because the '1' being shifted is a 32-bit int the result of the shift
will be a 32-bit result, so assigning it to a 64-bit variable is just
misleading.
In this case the code that triggers it is this:
size_t window_size = static_cast<size_t>(1 << shift_amount);
The destination is a size_t so the warning only shows up on 64-bit
builds and doesn't indicate a real bug. It's curious that the code
had a cast already - presumably to suppress some other warning - but
the cast is not in the ideal place and doesn't avoid this new warning.
Moving the cast allows shift_amount to be log2(size_t) and allows
enabling C4334 in Chromium.

This produces bit-exact output and doesn't have the performance sensitivity to vectorisation, giving a complexity decrease of the IntelligibilityEnhancer of about 30x in my local machine.

We must remove dependency on Chromium, i.e. we can't use Chromium's base/logging.h. That means we need to define these macros in WebRTC also when doing Chromium builds. And this causes redefinition.
Alternative solutions:
* Check if we already have defined e.g. CHECK, and don't define them in that case. This makes us depend on include order in Chromium, which is not acceptable.
* Don't allow using the macros in WebRTC headers. Error prone since if someone adds it there by mistake it may compile fine, but later break if a header in added or order is changed in Chromium. That will be confusing and hard to enforce.
* Ensure that headers that are included by an embedder don't include our macros. This would require some heavy refactoring to be maintainable and enforcable.
* Changes in Chromium for this is obviously not an option.
