Fix extension behavior in shader validation.
If an extension is not specified, it is disabled by default, thus a shader should fail compiling if features from that extension are used.

Emulate certain buil-in functions to work around driver bugs.
This is implemented by adding a new compile option SH_EMULATE_BUILT_IN_FUNCTIONS. The emulated functions are names as webgl_originalName_emu so there will never be naming conflicts.
At the moment only three functions are emulated: normalize, abs, sign. Also, the compile option will emulate all three. However, the mechanism to emulate only a selected subset is also imeplemented. It can be turned on easily.
ANGLEBUG=196
TEST=with this option, the failed test with abs.frag passes.

Implement ES2 backend for Angle translator.
With this CL, we have the option to select a code output backend: GLSL, GLSL ES, or HLSL.
Note that we always emit the highest supported float precision for fragment shader due to anglebug 168. Although this is a temporary solution, it's not against GLSL ES spec, because it's ok for implementation to upgrade precision.
Tested with WebGL conformance test suite, GLES2 conformance test suite (only failed 2/1198), and a few webgl demos, including worlds of webgl, aquarium, etc.
anglebug=81
test=translator emitting correct GLSL ES code when ES2 backend is selected.

Refactored ReadFileData() function in the translator sample to fix many issues:
- Memory leaks
- Made compiling using multiple strings default. This was not getting exercised.
- Removed redundant copies of file data
- Handled empty files properly which were getting ignored

Adding support for OES_standard_derivatives extension. This is not the complete implementation. Sending it to get feedback on the API. Is it OK to add extension support into TBuiltInResource? I could create a new struct for extensions but that would lead to API change.

Refactored the way symbol tables are initialized and stored. This was done in response to the addition of EShSpec.
Symbol table entries depend on three things - language, spec (not now but may eventually), and built-in resources.
We used to build two global symbol-tables - one for each language. During each compile, one of the symbol table was
copied and resource-specific stuff was added. I have moved the symbol table to TCompiler that gets initilized when
compiler is created and reused for each compile. This makes it much cleaner and extensible in case a spec requires
special entries to be added to the symbol table.
PS: Sorry for the long CL, but all of it needed to be done in one CL. I have verified that everything still compiles
and passes all conformance tests.

Added GYP build files. GYP files are needed for integration with chromium and cross-platform build for glsl translator. It would really be nice if we did not have to maintain two build systems. For now I have only moved the GLSL translator to gyp build system. Please note that the gyp files awkwardly have build_ prefix so they do not conflict with the manually-maintained sln files.
