When an attribute had the format "enum|integer", and a max or min
allowed value set, any value set for this attribute would have its
enum symbol's value checked against the valid integer range.
This would lead to the following:
android:numColumns="autofit"
being interpreted as an integer value of -1, which violated the minimum
expected value for numColumns, which was 0.

A resource defined like so:
<item type="drawable" name="foo" />
should be assigned the value @null.
The only exception is for <string> resources, which are given the
empty string value (since <string></string> is ambiguous). The decision
to use "" is based off the fact that old AAPT used to assign "" to all
undefined resources, even non-string ones.

Previously style overlays would completely override an existing style.
To be compatible with AAPT, styles now merge with the overlay, allowing
the overlay's attributes and parent to take precedence.
