[PATCH] Correct various inconsequential typos.

["Giuliano Procida via libabigail" <libabigail@sourceware.org>]

In the leaf reporter member subtype changes are labelled as plain
changes and vice versa. This was probably due to the different
ordering of the code sections in the default and leaf reporters.
Output is unchanged as these tags currently map to the same strings.

When generating diff reports there were some rare cases where a
pretty representation might have been emitted twice or the trailing
whitespace might have been missing.

	* src/abg-leaf-reporter.cc: report(class_or_union_diff) Swap
	calls to report_mem_header to match the rest of the code.
	* src/abg-reporter-priv.cc: represent(var_diff_sptr) Add some
        missing whitespace; remember we've emitted the pretty
        representation in 2 cases where this was omitted (though 1 of
        these is the last case where it makes no difference).
        maybe_report_diff_for_symbol Add some missing whitespace;
        remember we've reported a diff (and need a trailing newline)
        in 1 case where this was omitted, also affecting the
        return value of the function (but no caller cares).
