fix($http): return empty headers, ignore properties in Object prototype

Fix response headers with an empty value Empty response header values are legal
(http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html).

The headers getter fn will now only return null if the header property is not an own property.

feat(ngPluralize): add support for `count` to be a one-time expression

Closes #10004
feat(ngMaxlength): add support for disabling max length limit

Previously, setting the maxlength to a negative number, would make all
input values invalid (since their length should be less than maxlength,
which is impossible).
This commit changes the behaviour of maxlength/ngMaxlength, effectively
disabling the maxlength validation (always returning true) when maxlength
is set to a negative number. This is more inline to how the HTML5
`maxlength` attribute works (both in browsers and according to the spec:
http://dev.w3.org/html5/spec-preview/attributes-common-to-form-controls.html#attr-fe-maxlength).
