Pass original value to sanitize_option_* filter

[simonwheatley]

Currently the sanitize_option_{$option_name} filter differs from other esc and sanitization filters in that it does not pass the original value. It should.

[simonwheatley]

Adds the original value to the sanitize_option_* filter (now without my dirty test which breaks TwentyThirteen)

Refreshed for 4.0a trunk

I've refreshed the patch:

• The intended effect still works (original value passed as a third parameter)
• Four unit tests fail, see below, but these appear unrelated
