init the binlog_cache (THD::transaction.trans_log).

it may not be inited in some cases, we have to be cautious
(will forward this commit mail to Heikki).

I am fixing it here in 4.1, not in 4.0, as it goes with another change
which I did in 4.1 (fix for BUG#3204
""mysqlbinlog --read-from-remote-server this_binlog.001" prints all binlogs").

we now detect that the server is sending us a log which we did not request
by testing the info in the fake Rotate event.
I also changed code to not print the fake Rotate which describes the
log we asked for (it's always the first received event but old masters
may not send it).

  Remove includes of sys/types.h and sys/stat.h because these are already included through univ.i

Portability fixes

  Add a comment that InnoDB always retrieves the row id, if the clustered index was internally generated by InnoDB. Then we know the 'ref' to the row.
