This will be needed by 'gotadmin pack'.

This catches invalid reference names passed to 'got ref -l' and will also be needed to validate reference names passed to a future 'gotadmin pack' command. ok naddy@

Code which inserts a reference into a reflist passes ownership of this reference to the list. However, got_ref_list_free() never closed such references, which resulted in a memory leak. ok tracey

Create automatic "backup" references which ensure that objects from the pre-rebase or pre-histedit state remain in the repository. A new -l option for 'got rebase' and 'got histedit' lists old commits. This makes it easier to recover from botched rebase or histedit operations. Removal of such objects currently requires got ref -d and git-gc. This will be made more convenient in the future. testing and ok jrick
