[libvirt] [PATCH 0/5] Reorganize storage auth (both disk and pool)

While understandably not really a 1.2.6 candidate, I figured I'd post this now in hopes that it gets the ball rolling. The changes will help with a related bz to support libiscsi for SCSI passthrough devices where a <hostdev> entry for an iscsi adapter would be able to have <auth> data. The bulk of changes are code motion/merge. The details for each are: The first patch will create new API's which will then be used by the parse domain disk and the parse storage pool code if the "<auth" element is found. The logic merges the parsing found in the domain disk and storage pool code with one slight caveat - the domain disk code expects to find "<secret type='xxxx'", where xxxx is 'iscsi' or 'ceph'. Trying use the Type{To/From}String API's in virstoragefile.c resulted in a link time failure (even though secret_conf.h was included). Never quite figured it out - I will take suggestions though. Although since the domain disk code is all that really cares about it and the domain_conf code can use the Type{To/From}String API's - I just left it as is. The new copy API is used when the pool code needs to copy it's auth data into each domain disk's auth entry. The second patch will fix a not-run test that tests the auth. It seems it was not added to the active list of tests because the output generated did not include the "usage" information (eg " usage='mycluster_myname") that is part of the <secret> element. Additionally because it did not include it the output was "<secret type='iscsi' </auth>". So rather than ignore the test - add to the filters to avoid looking for "<secret" - through to the closing ">". The -auth.xml and -auth.args files needed adjustments to follow the non "-auth" version of the files that have changed over time, but not also changed int the "-auth" files. The third patch will cause the domain disk algorithms to utilize the new generic parse and format APIs as well as using the 'authdef' instead of the inline structure fields. This patch also restores the checking for </auth> in the recently restored auth test. Still avoiding the whole <secret... /> line as I saw no way to filter just the usage that's in the stored XML file. The fourth patch is a mostly innocuous html change - it could go early, but it just felt better in this place. The fifth patch will cause the storage pool algorithms to utilize the new generic parse/format API's as well as new authdef structure for accessing the data. The removal of the duplicated cephx/chap structures seems (in my mind at least) to simplify things. They were essentially copies of each other with no seemingly real value in keeping separate other than the visual in the code of ".chap." or ".cephx.".
