release-2.5.5

Added

• #44, #45, #46, #47, #48, and #49 prepare the documentation for publication at https://zendframework.github.io/zend-http/

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #87 fixes the ContentLength constructor to test for a non null value (vs a falsy value) before validating the value; this ensures 0 values may be specified for the length.
• #85 fixes infinite recursion on AbstractAccept. If you create a new Accept and try to call getFieldValue(), an infinite recursion and a fatal error happens.
• #58 avoid triggering a notice with special crafted accept headers. In the case the value of an accept header does not contain an equal sign, an "Undefined offset" notice is triggered.
