Subject: [PATCH 03/42] Make the new attr/prop changes pass the test suite (in
 Webkit).  There are still errors in IE.

+ Added hooks for selected, checked, readonly, disabled to removeAttr if set to falsey

+ Removed all attrs from attrFix, these aren't needed for setAttribute

+ If prop is used for class, do we want a propFix for class?

  - We could just assume the user should know to use className with prop.  I've done the latter for now.

+ Created tests for $.fn.prop and $.fn.removeProp

  - Actually all I did was change broken attr tests to prop where it made sense.

Subject: [PATCH 10/42] Full test suite now passes in all browsers! There are
 probably some tweaks we can make to shorten and simplify.

- removeAttr now only uses setAttribute if camelCase setAttribute is not supported

  + Might want to rename jQuery.support.getSetAttribute

- tabIndex is a special case now for hooks where undefined should be returned.

  + Should we be checking if hooks returns undefined?  undefined might be the desired return value in future hooks.
    As of now, tabIndex is the only one that needs it, but the test suite will still pass if we don't check if hooks are undefined.

Subject: [PATCH 15/42] Restored 6 tests that I had commented to come back to
 later to split up between prop and attr.  All tests still pass in all
 browsers.

- I should make it clear that I have not removed any tests, but only moved some attr tests to prop where I thought it was appropriate.

Subject: [PATCH 20/42] Fix #7472 and added test for #3113

- Forms with an input that has either name="action" or name="some-other-attr-on-the-form" caused problems in IE6/7.  This is fixed.

- Changed check in $.attr for ret === null to typeof ret === "object" to catch any inputs that are accidentally retrieved in IE6/7, since attributes cannot be set to objects and typeof null === "object"

- Normalize set value to string to synchronize return type cross-browser

- Add style attrHook to propHooks to support style getting in all browsers for both attr and prop

- Extend the selected propHook instead of overriding a possible set function

- Remove selected propHook TODO since there is no selected content attribute and it should return null

Subject: [PATCH 39/42] Found a problem removing the style attribute in IE

- Style is now a special case in IE6/7 to set cssText.  My goal is to avoid calling attr again for the performance benefit, and at this point it would also cause an infinite loop for the boolean attributes hooks such as selected & checked.  Nevertheless, style seems to be the only one requiring a special call.

Subject: [PATCH 42/42]  #8150 - When removing the width and height attributes
 in IE6/7, setting to "" actually sets to 0 instead of auto

- Having fixed this automatically with the use of removeAttribute in browsers that support it, this will fix it for IE6/7 as well.

- This has no effect on width/height styles set elsewhere( test added to removeAttr )

- With this addition, I need to call attr in removeAttr for IE6/7, which means boolean calls like .attr("checked", "") will no longer remove the attribute, which I think is fine.  .attr("checked", false) will still remove.  If I had left it, it would have gone in an infinite loop since setting to empty string is the only way to remove it in these browsers.

- The hrefNormalized hooks were returning null if they weren't present.  Added the null check to the getter.

- Now that the style support fails in IE8 as well due to uppercasing everything, no need to have style included with the hrefNormalized hooks
