unprotectedRenameTo and Non-Existent Parent Directory

[Dennis Kubes]

Currently calls to unprotectedRenameTo in FSDirectory will not create 
parent directories of the rename path.  Should this behavior be changed 
to create the parent directories if they do not exist?

This is effecting the LinkDB install method.  For example if I am 
creating a linkdb by the name of crawl/linkdb the install method calls a 
rename from working directory (something like linkdb-1234...) to 
crawl/linkdb/current.  But if the crawl/linkdb directory does not 
already exist then the rename fails.
