OK, I took a stab at removing it from the manual and added the
information it contained to the doc strings of the relevant functions
instead.  Please see attached patch -- WDYT?

Thanks,

Subject: [PATCH] Remove upload functionality of package-x from the elisp
 manual

Suggested by Stefan Monnier.
Ref: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=19537#8

* doc/lispref/package.texi (Package Archives): Don't document
package-x upload functions in the elisp manual, since they are not
very commonly used.  (Bug#19537)
* lisp/emacs-lisp/package-x.el (package-archive-upload-base)
(package-upload-buffer, package-upload-file): Add to the doc strings
any details removed from the elisp manual that would otherwise be
missing.
