Here's a second version based on feedback from Kyle and Peter. Thanks
both for your comments.

It drops the "tolower" patches, which are not used anymore, and makes
the parsing of content-types and their parameters a bit more robust.

  [1/8]: test-lib: preserve GIT_CURL_VERBOSE from the environment
  [2/8]: t/lib-httpd: use write_script to copy CGI scripts
  [3/8]: t5550: test display of remote http error messages

    These three are the same as before.

  [4/8]: http: extract type/subtype portion of content-type

    Make our content-type matching more robust, both for the errors and
    for matching smart-http types.

  [5/8]: http: optionally extract charset parameter from content-type

    Feature work to support 7/8.

  [6/8]: strbuf: add strbuf_reencode helper

    Same as before (feature work to support 7/8).

  [7/8]: remote-curl: reencode http error messages

    The actual fix.

  [8/8]: http: default text charset to iso-8859-1

    This could be part of 5/8, but I floated it to the top of the heap
    to make it easier to discuss/adjust it.
