In log_event.h
      
DESCRIPTION:
Due to inclusion of an implementation file, namely 'rpl_tblmap.cc'
in a header file, namely 'log_event.h'; linker errors occur if
log_event.h is included in an application containing multiple source
files, such as in the case of Binlog API.
      
Binlog API requires including log_event.h in its source files;
which leads to multiple definition errors, for functions defined
in rpl_tblmap.cc for class 'table_mapping'.
            
FIX:
Change the inclusion from header file(log_event.h) to source files
using this header and have flag MYSQL_CLIENT set. The only file in
the current server repository is mysqlbinlog.cc.

client/mysqlbinlog.cc:
  Pulled in code of rpl_tblmap.cc
sql/log_event.h:
  Removed inclusion of the implementation file from this header file
