Hello, this is various minor setup improvements, including:

• Utilizing rake-compiler's compile task ...(a)
• More standard way to require Ruby modules (using require_relative and unshifting to $LOAD_PATH)
• Use the standard stdbool.h header for boolean type and values
• Prevent loading error of the uri gem by explicitly requiring in advance

Additional note about (a)

The custom ext:build task seems to cause a race issue between clobber and compile in some case like invoking rake compile test:
