[PATCH] Resolves: fdo#37195 CreateProcessServiceFactory can't happen before sync

[Caolán McNamara]

If CreateProcessServiceFactory is called, then common.rdb of
"Users/YOU/AppData/Roaming/LibreOffice/3/user/extensions/bundled/registry/
com.sun.star.comp.deployment.component.PackageRegistryBackend/common.rdb" is
opened mmapped

On a new start of an LibreOffice which wants to synchronize new config over an
old config, then it will want do a copy of
"install/share/prereg/bundled/registry/
com.sun.star.comp.deployment.component.PackageRegistryBackend/common.rdb"
over
"Users/YOU/AppData/Roaming/LibreOffice/3/user/extensions/bundled/registry/
com.sun.star.comp.deployment.component.PackageRegistryBackend/common.rdb"
which will fail on windows with error 1224, i.e. ERROR_USER_MAPPED_FILE

That aborts the copy_bundled_recursive copy, leaving an old config
pointing to the old location of dictionaries.

So for windows at least, CreateProcessServiceFactory shouldn't happen before
copy_bundled_recursive.
