BUG#16698172-CANNOT DO POINT-IN-TIME RECOVERY FOR

SINGLE DATABASE; MYSQLBINLOG
      
Problem: If last subevent inside a RBR event
is skipped while replaying a binary log
using mysqlbinlog with --database=... option,
generated output is missing end marker('/*!*/;)
for that RBR event. Thence causing syntax error
while replaying the generated output.
      
Fix: Append end marker ('/*!*/;) if the last 
subevent is getting skipped.
Append end marker if the last 
subevent is getting skipped.

client/mysqlbinlog.cc:
  Append end marker if the last 
  subevent is getting skipped.
