[Libguestfs] [p2v PATCH 3/6] gui: set row count from a running variable when populating tables

Each call to table_attach() in fact open-codes (row, row + 1), for setting
the top and bottom grid lines of the widget being added to the table.
What's more, within a given table, we add widgets in a left-to-right
first, top-down second fashion, so "row" only ever increases within a
particular table.
Modify the table_attach() macro to calculate "bottom" automatically, plus
replace the open-coded "row" constants with actual (incremented) "row"
variables.
(This patch is easiest to review with "git show --word-diff=color".)
Don't do the same simplification for colums, as we're going to introduce a
multi-column widget next.
Note that one definition of table_attach() now evaluates "top" twice.
Preventing that would be a mess: we could be tempted to introduce a do {
... } while (0) block with a block-scope auto-storage variable. However,
it could trigger gcc warnings (about shadowing other variables), in which
case we'd end up copying NBDKIT_UNIQUE_NAME() from nbdkit, which is
totally overkill. So just evaluate "top" twice; it's not a complex or very
widely used macro. (BTW, the previous replacement text of the *other*
definition of table_attach() used to evaluate "top" twice as well.)
