/*****************************************************************************
Replication IO Thread
Master_info contains:
- information about how to connect to a master
- current master log name
- current master log offset
- misc control variables
Master_info is initialized once from the master.info file if such
exists. Otherwise, data members corresponding to master.info fields
are initialized with defaults specified by master-* options. The
initialization is done through init_master_info() call.
The format of master.info file:
log_name
log_pos
master_host
master_user
master_pass
master_port
master_connect_retry
To write out the contents of master.info file to disk ( needed every
time we read and queue data from the master ), a call to
flush_master_info() is required.
To clean up, call end_master_info()
