[PATCH] http: fix charset detection of extract_content_type()

[nori <semtlenori@gmail.com>]

extract_content_type() could not extract a charset parameter if the
parameter is not the first one and there is a whitespace and a following
semicolon just before the parameter. For example:

    text/plain; format=fixed ;charset=utf-8
