* "Fix", or canonicalise, the meta-data of the files in a store path

* after it has been built. In particular:
|
|
*
|
|
* - the last modification date on each file is set to 1 (i.e.,
|
|
* 00:00:01 1/1/1970 UTC)
|
|
*
|
|
* - the permissions are set of 444 or 555 (i.e., read-only with or
|
|
* without execute permission; setuid bits etc. are cleared)
|

*
|
|
* - the owner and group are set to the Nix user and group, if we're
|
|
* running as root. (Unix only.)

|
|
* If uidRange is not empty, this function will throw an error if it
|
|
* encounters files owned by a user outside of the closed interval
|
|
* [uidRange->first, uidRange->second].
