Subject: [PATCH] tools lib traceevent: Introduce extend_token()

The __read_token() function has some duplicated code to handle
internal buffer overflow. Factor them out to new extend_token().

According to the man pages of realloc/free(3), they can handle NULL
pointer input so that it can be ended up to compact the code.  Also
handle error path correctly.
