File storage max upload limit reform:the max upload limit will now default to empty. Rationale: this value isone that ages quickly with respect to new storage requirements, and iscurrently set to something incompatible with the vanilla Naviserver configuration(500MB fs vs 20MB ns).The upgrade script will make so that instances setting this parameterhigher than the server upload limit configuration will beset empty as well (this would never have an effect, as serverwill prevent the upload altogheter anyway).Max upload limit in bytes is now retrieved from a proc implementingthis fallback to server configuration logics. Other than centralizing,its purpose is to be used in client-side code checks in the futureso we could prevent a doomed upload in advance.
