`curl_copy_handle()` already registers a new resource, so we must not
increase the refcount of the original resource.

Fix #79013: Content-Length missing when posting a curlFile with curl

Unfortunately, some Webservers (e.g. IIS) do not implement the (F)CGI
specifications correctly wrt. chunked uploads (i.e. Transfer-encoding:
chunked), but instead pass -1 as CONTENT_LENGTH to the CGI
application. However, our (F)CFI SAPIs (i.e. cgi and cgi-fcgi) do not
support this.

Therefore we try to retrieve the stream size in advance and pass it to
`curl_mime_data_cb()` to prevent libcurl from doing chunked uploads.
This is basically the same approach that `curl_mime_filedata()`
implements, except that we are keeping already opened streams open for
the `read_cb()`.

Fix #79019: Copied cURL handles upload empty file

To cater to `curl_copy_handle()` of cURL handles with attached
`CURLFile`s, we must not attach the opened stream, because the stream
may not be seekable, so that we could rewind, when the same stream is
going to be uploaded multiple times. Instead, we're opening the stream
lazily in the read callback.

Since `curl_multi_perfom()` processes easy handles asynchronously, we
have no control of the operation sequence. Since duplicated cURL
handles may be used with multi handles, we cannot use a single arg
structure, but actually have to rebuild the whole mime structure on
handle duplication and attach this to the new handle.

In order to better test this behavior, we extend the test responder to
print the size of the upload, and patch the existing tests accordingly.

libcurl 7.29.0 has been released almost eight years ago, so this

also allows us to get rid of quite some conditional code and tests
catering to very old libcurl versions.
