worked around gcc bug to make compile-pentium-gcov work

increase coverage for table.cc in mysql_rm_table()
ingore temporary gcov files
fixed bug in replication test case


BitKeeper/etc/ignore:
  added *.da
BUILD/compile-pentium-gcov:
  do not build shared libraries - combination of -fPIC and the coverage flags
  triggers a bug in gcc, apparently - problem went away after adding
  --disable-shared
mysql-test/t/flush.test:
  extra test to increase coverage of table.cc
mysql-test/t/rpl000016.test:
  fixed bug in test case - insert may be concurrent, so we may read the
  table on the slave before the last insert becomes visible even when the 
  master position is up to date if we do not
  lock it explicitly
