lib/igt_aux: Polish docs for igt_interruptible

- Give __ prefix to internal funcstion and structs, only
  igt_interruptible is used by tests.

- Move docs to igt_interruptible and adjust.

- Explain more clearly how the timeout is getting doubled each
  iteration until no more interruptions happen. Also rename the
  argument to give it a more meaningful name in the docs.

- Link from other functions to this one for cross-referencing.

- Rename to igt_do_interruptible to make it clearer it's a loop,
  inspired by do {} while () loops.

v2: Rename instead to igt_while_interruptible and fix typos (Chris).
And add gtk-doc for igt_ioctl, too.
