HTTP parser: fixed parsing of target after literal space character.

In theory, all space characters in request target must be encoded; however,
some clients may violate the specification.  For the sake of interoperability,
Unit supports unencoded space characters.

Previously, if there was a space character before the extension or arguments
parts, those parts weren't recognized.  Also, quoted symbols and complex
target weren't detected after a space character.
