bug#21594: 25.0.50; (elisp): node `Variable Definitions' is not reachable by `i variable definition'

[Drew Adams]

The problem is more the node name than the index entry.  The node title,
within the node, is `Defining Customization Variables', which is much
better.

I imagine that the node name was picked because the node is a subnode of
node `Customization', but that is not a good enough reason.
`Info-goto-node' handles the nodes of a manual in a flat way.

A node named `Variable Definitions' should cover all of defvar,
defconst, and defcustom.  Likewise, an index entry named `variable
definition'.  IOW, someone hunting for info about variable definitions
should be able to get to general info about all kinds of variable
definitions.
