Subject: fix for #1344 handling of init-file option added to embedded library
 main problem was killing of output (resulting recordsets etc) i added checks
 for empty output in Protocol:: methods better solution could be special
 Protocol_nul class to redirect results to nowhere

libmysqld/lib_sql.cc:
  code was added to call read_init_file
  Protocol methods now can support output to nowhere
sql/mysqld.cc:
  bootstrap function extended to work in embedded library
sql/sql_parse.cc:
  handle_bootstrap modified to work in embedded library
