OK after long tests StoreID works for both mem and UFS store.

OK after long tests StoreID works for both mem and UFS store.
I solved and marked all mismatching tests and for now it seems to work
perfectrly:

The scenario I have been using is .ytimg.com domain.
It hosts many jpg pictures on different CDN's.
the examples are:
http://i2.ytimg.com/vi/Vo0Cazxj_yc/default.jpg
The ID of the img is the uri_path "/vi/Vo0Cazxj_yc/default.jpg"
The domain is a subdomain of ytimg.
so my match would be all subdomains of ytimg ->
ytimg.squid.internal/url_location.

the reuslt is:
http://i2.ytimg.com/vi/Vo0Cazxj_yc/default.jpg ==
http://i2000.ytimg.com/vi/Vo0Cazxj_yc/default.jpg ==
http://abc555.ytimg.com/vi/Vo0Cazxj_yc/default.jpg

This is a basic cdn example.

They idea pseudo for now is:
store the storeID in request from the helper.
next after all callouts from helpers and adaptation move store it in the
ClientHttpRequest->store_id.
Then on StoreEntry creation use the store_id instead of
ClientHttpRequest->uri.

this solves almost anything related to "mem-obj->url" and will force
changing it to "mem-obj->store_id".

Adding couple specific checks to point into the store_id will make the
feature integration the least invasive to store and other code in squid.

The helper code for now Is too much for me and I will get back to it
when later Amos will have more time and This part of the patch will be
ready steady and documented.

In the mean while I will write in the wiki more about the feature.
