This patch corrects a problem encountered when reading the binlog from a remote
host. The application was crashing because the buffer variable (temp_buf) in
log_event was not pointing to the incoming data. For a normal file read, this
buffer is allocated by a previous call of read_log_event. However, when reading
from a remote host, the first call to read_log_event is not executed therefore
no buffer is allocated. Furthermore, there is no need to allocate a new buffer
because the incoming stream is what needs to be read.
This patch adds the call to initialize the temp_buf variable if reading from a
remote host. It also adds a check at destroy time to ensure the temp_buf is not
freed if reading from a remote host.

BUG#17654 : --read-from-remote-server causes core
This patch corrects a problem when reading from a remote host. The temp_buf
variable of the log_event class is undefined. This patch assigns the temp_buf
variable to the address of the incoming stream. This allows the print functions
to print the binlog events correctly.
