When a file is renamed, include old file name in Patch attribute
When a file is renamed, the value of `file` in the Patch attribute
is the new file name. The old file name is not included.
This means it is not possible to find the old file name by running
a gerrit query command.
Add a new field `fileOld`. When the file is renamed, this field
contains the old file name.
The name of the existing field is unchanged. Renaming to `fileNew`
would make the name more meaningful and consistent with `fileOld`,
but would make it incompatible with user scripts that expect it to
be called `file`.
