[TYPO3-core] RFC: Bug 4623: Content encoding with x-gzip not possible in IE7

[Oliver Hader]

This is a SVN patch request.

Problem:
IE7 can't handle pages with "Content-Encoding: x-gzip" set in HTTP
headers. Furthermore "x-gzip" normally is used only for the Content-Type
(e.g. MIME type) and not for the Content-Encoding.

Solution:
Change the information in the "Content-Encoding" header from "x-gzip" to
"gzip" and also evaluate HTTP_ACCEPT_ENCODING correctly in cosideration
of qvalues. If the browser sends "Acept-Encoding: gzip;q=0,deflate",
this means that gzip shouldn't be used for this browser (see HTTP/1.1
specs, RFC 2616).

Comments:
I added missing JavaDoc comments to the class and fixed some line
formatting. I attached three patches to this RFC:
* 0004623_v2.patch - is the one I'd like to commit
* 0004623_v2_w.patch - is without changes to whitespaces
* 0004623_v2_reduced.patch - is reduced to show only the code changes
