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.

Fix test cases to pass for a plain ./configure && make build. This includes disabling two test cases when certain features are not present in the server. We're not losing coverage from this because these features are usually present, and disabling them here only serves the purpose to make the test cases work in the unlikely case that they aren't.

fixes
Adding an event that can be used to denote that an incident occured
on the master. The event can be used to denote a gap in the replication
stream, but can also be used to denote other incidents.
In addition, the injector interface is extended with functions to
generate an incident event. The function will also rotate the binary
log after generating an incident event to get a fresh binary log.
does not work): Changing packed row format to only include null bits
for those columns that are present in the row as well as writing BIT
columns in a storage engine-independent format.
The change in row format is incompatible with the previous format and a
slave will not be able to read the new events.
