s/detected in it/detected in the extension
as this is harder to guess whether the policy itself corrupted or the extension
did.

Comment simplified (Note that this struct moved to extension_downloader.h)

+    bool is_corrupt_policy_reinstall;

(again feel free to suggest something better)
in order to clear the confusion i mentioned above, maybe sth like:
is_policy_reinstall_due_to_corrupt_extension or something that disambiguates
which of policy or extension is corrupt.

This moved to extension_downloader.h, and I changed this member's name to
"is_corrupt_reinstall" to match the variable usage there.
