Interface design for user-defined name hashing.
1) We use BuiltInResources to pass the hash function to
ANGLE, deciding whether we applies hash function or not.
2) We use 64 bits hashing function, because 64 bits is 16
bytes using hex representation, plus the "webgl_" prefix,
we can keep the names under 128 (WebGL allows 5 levels of
nesting in structures). If chooseing 128 bits, we will
go beyond 128 characters, and some drivers can't handle
that safely.

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.

Implement shader identifier name mapping.
The name mapping happens when an identifier is longer than 32 characters. The name mapping is behind a flag, so it won't happen by default. Also, functions to query the mapped names are added.
The purpose of this CL is for the drivers that can't handle long names. For example, linux NVIDIA driver can't handle 256 character name, whereas WebGL spec requires that.
This CL also fixes the issue that some of the TIntermSymbols' ids are 0s.

Moved the global-pool-allocator to TCompiler so that all memory allocated by the compiler can be de-allocated. Earlier the global-pool-allocator kept accumulating memory from all compilers (symbol-table in particular). The memory was only de-allocated when gpu-process exited or ShFinalize() was called. This was a problem for Chromium which keeps the GPU process around for the browser session. Now the memory is de-allocated as soon as the compiler is deleted, which happens when a tab is closed.

De-allocate memory in ShFinalize(). There still seems to be a bug here if the translator is used in a multi-threaded environment. It seems memory local to only one thread is being deallocated - the thread from which ShFinalize() is called. I will look into it closely in the next CL.

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.

ShInitialize/ShFinalize is designed to be called once per process, or it would crash at random locations. I changed ShFinalize() to properly cleanup and reset global variables so that they can be called multiple times. I think that the compiler setup is much more complicated than it needs to be. It unnecessarily uses global variables. A custom pool allocator is overkill too.

Minor reshuffling of directory structure in preparation of ESSL to GLSL compiler work.
1. Added include/GLSLANG which includes compiler API
2. Deleted src/include and moved the header files to the same directory as the corresponding source files
3. Modied include path to be relative to src/. I have only fixed paths for files I moved. We should fix it for all new files at least. It is much easier to see where an included file is coming from.
I noticed that a few libGLESv2 source files include headers from libEGL project, which seems wrong. I think we should address this issue. Next step: move compiler source files to compiler/frontend and create two new projects compiler/glsl_backend and compiler/hlsl_backend.
