In particular, read the URL, the source name, and both the summary and
the description. For the long description, add a small system to read
continuation lines.
Adapt the expected result of virt-inspector for Debian and Ubuntu phony
guests, so test-virt-inspector.sh still passes.
The inspection code already computed the paths of the software hive
(twice!) and the system hive, plus we also recompute the same paths
elsewhere, in virt-v2v for example. Therefore it makes sense to store
the paths from the inspection code and make them available through two
new APIs.
Pass the HIVEX_OPEN_UNSAFE flag when opening hives for reading.
Do NOT pass it when opening hives for writing.
This should make inspection, virt-win-reg and virt-v2v more tolerant
about handling Windows Registry corruption, without increasing the
risk of causing new corruption in hives.
