[PATCH 03/12] [gdb] Use using instead of typedef some more (part 3)

[Tom de Vries <tdevries@suse.de>]

Fix the remaining hits of:
...
$ find gdb* -type f -name "*.[ch]" -o -name "*.cc" \
    | egrep -v /testsuite/ \
    | xargs grep '^[ \t]*typedef .*;.*$' \
    | grep -v WINAPI
...
except for C example in a comment.
