Standardize copyright notices to project style
For all "ANGLE Project" copyrights, standardize to the format specified
by the style guide. Changes:
- "Copyright (c)" and "Copyright(c)" changed to just "Copyright".
- Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1").
- Fixed a small number of files that had no copyright date using the
initial commit year from the version control history.
- Fixed one instance of copyright being "The ANGLE Project" rather than
"The ANGLE Project Authors"
These changes are applied both to the copyright of source file, and
where applicable to copyright statements that are generated by
templates.

Work around atan(y, x) bug on NVIDIA
atan(y, x) is not always returning expected results on NVIDIA OpenGL
drivers between versions 367 and 375. Work around this by emulating
atan(y, x) using the regular atan(x) function. A fix to the driver is
expected in a future release.
It is most convenient to implement the vector atan(y, x) functions by
using the scalar atan(y, x) function. Support for simple dependencies
between emulated functions is added to BuiltInFunctionEmulator. In the
current implementation one function is allowed to have at most one
other function as its dependency.

translator: Scope all classes with "sh".
I was seeing an odd problem with our PoolAlloc conflicting with the
glslang/Vulkan TIntermNode, so the fix was to move everything to a
separate namespace.
The bison grammars are also regenerated. No functional changes.

Workaround isnan() on Intel drivers
On some Intel drivers, calling function isnan() on highp float will get wrong
answer. This patch work arounds this bug by using an expression to emulate
this function.

Work around abs() issue in Intel Mac drivers

Move some output out of BuiltInFunctionEmulator subclasses
This paves the way for getting rid of the BuiltInFunctionEmulator
subclasses in favor of initializing the BuiltInFunctionEmulator
dynamically in Compiler subclasses. The eventual goal is getting rid of
GLSL output specific functionality in Compiler, which should be
language-agnostic.

Clean up BuiltInFunctionEmulator public interface
This removes all language-specific bits from BuiltInFunctionEmulator
parent class, and makes the public interface of BuiltInFunctionEmulator
minimal.
Writing comments around emulated function definitions is removed from
OutputHLSL, they are not necessary as the emulated function definitions
are just another part of the shader header.

Implement hyperbolic function support for ESSL 3.00
Emulating arc hyperbolic functions is required on HLSL, where they do
not exist natively. For this, BuiltInFunctionEmulator is split into GLSL
and HLSL subclasses. The GLSL subclass handles the pre-existing built-in
emulation implemented for working around OSX bugs, and the HLSL subclass
handles emulating asinh, acosh and atanh on HLSL.
