// Remove any existing UserInstallation's extensions cache data remaining from
// old installations.  This addresses at least two problems:
//
// For one, apparently due to the old share/prereg/bundled mechanism (disabled
// since 5c47e5f63a79a9e72ec4a100786b1bbf65137ed4 "fdo#51252 Disable copying
// share/prereg/bundled to avoid startup crashes"), the user/extensions/bundled
// cache could contain corrupted information (like a UNO component registered
// twice, which got changed from active to passive registration in one LO
// version, but the version of the corresponding bundled extension only
// incremented in a later LO version).
//
// For another, UserInstallations have been seen in the wild where no extensions
// were installed per-user (any longer), but user/uno_packages/cache/registry/
// com.sun.star.comp.deployment.component.PackageRegistryBackend/*.rdb files
// contained data nevertheless.
//
// When a LO upgrade is detected (i.e., no user/extensions/buildid or one
// containing an old build ID), then user/extensions and
// user/uno_packages/cache/registry/
// com.sun.star.comp.deployment.component.PackageRegistryBackend/unorc are
// removed.  That should prevent any problems starting the service manager due
// to old junk.  Later on in Desktop::SynchronizeExtensionRepositories, the
// removed cache data is recreated.
//
// Multiple instances of soffice.bin can execute this code in parallel for a
// single UserInstallation, as it is called before RequestHandler is set up.
// Therefore, any errors here only lead to SAL_WARNs.
//
// At least in theory, this function could be removed again once no
// UserInstallation can be poisoned by old junk any more.
