The numberOfChannels array on AudioBuffer is now an infallible array, as this
is considerably smaller than infallible channel data array allocations in
AllocateAudioBlock and similar to channel data pointer array allocations in
AudioChunk.

OfflineAudioCompletionEvent needs to use AudioBuffer for its output,
and so the AudioContext should run at the rates supported by AudioBuffer.

Also change WebAudioUtils from a class to a namespace, so that constant
variables can be defined inline with internal linkage.
static class variables cannot be defined inline because this violates the one
definition rule, even though some compilers may not notice.

float did not necessarily have enough precision.
Includes a -1 fix in the multiplier of the input signal to have
"a signal level of zero corresponding to the center value of the curve array".

Use the sample rate passed to the OfflineAudioContext constructor in
MediaStreamGraph::CreateOfflineInstance, and pass the preferred mixer sample
rate to the (real time) MediaStreamGraph constructor.
Then, always use this sample rate for the lifetime of the graph.
This patch needed to pass the sample rate to the AudioMixer class to avoid
relying on globals like it was done before.

This patch was mostly generated with the following command:
find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapObject(JSContext/ {; N; s/\(WrapObject(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i ""
and then reverting the changes that made to
dom/bindings/BindingUtils.h, since those WrapObject methods are not
the ones we're trying to change here, plus a bunch of manual fixups
for cases that this command did not catch (including all the callsites
of WrapObject()).
This patch was mostly generated with this command:
find . -name "*.h" -o -name "*.cpp" | xargs sed -e 's/Binding::Wrap(aCx, aScope, this/Binding::Wrap(aCx, this/' -e 's/Binding_workers::Wrap(aCx, aScope, this/Binding_workers::Wrap(aCx, this/' -e 's/Binding::Wrap(cx, scope, this/Binding::Wrap(cx, this/' -i ""
plus a few manual fixes to dom/bindings/Codegen.py, js/xpconnect/src/event_impl_gen.py, and a few C++ files that were not caught in the search-and-replace above.
The difference from Blink here is that Blink plays silence for if element
channel counts are > 32, but here more channels are down-mixed. Media stream
channel counts are also fixed to 2 in Blink, but that restriction is not
applied here.
Leaving the "inline" const static/class member initialization of
MaxChannelCount left missing symbols with gcc 4.7.3.
