c777fc2c4c Scanning: 1) rationalize end-of-input everywhere, 2) prevent infinite loop at end-of-input, 3) use positive chars.
Fixes issue #25. (char 255 aliased to -1 and missing tests for end of input).

1) All layers of input scanning now share a single EndOfInput value.
This avoids translation of it across layers of encapsulation.

2) Some places looking for end of line were not stopping on EndOfInput.

3) Use of "char" for the input made char values > 127 be negative numbers.
This allowed for aliasing of 255 to -1, etc.  This is fixed by using
unsigned char.

bb8c3de8b3 glslang parser: Fix crash for ES shader with a uniform block with an unsized array that is later accessed. David Neto (dneto@google.com).
Instead of crashing, exit early from the implicit-sized-array-size-update routine so we can get to a real error message which is emitted later.

c027579631 Put in infrastructure for tessellation, geometry, and compute stages, and partially flesh out with built-in functions.
Added the built-in functions EmitVertex(), EndPrimitive(), barrier(), memoryBarrier(), memoryBarrierAtomicCounter(), memoryBarrierBuffer(), memoryBarrierImage(), memoryBarrierShared(), and groupMemoryBarrier().

Have not added any new built-in variables.

Also changed the linear performance relateToOperator() to a high-performance version.
