the buffer is computed based on how much base64-encoded data

there were, so there should be ample space for the data (maybe

even too much, since a statement can consist of a considerable

BUG#19459 (BINLOG RBR command does not lock tables correctly causing
crash for, e.g., NDB):
Before, mysqlbinlog printed table map events as a separate statement, so
when executing the event, the opened table was subsequently closed
when the statement ended. Instead, the row-based events that make up
a statement are now printed as *one* BINLOG statement, which means
that the table maps and the following *_rows_log_event events are
executed fully before the statement ends.
Changing implementation of BINLOG statement to be able to read the
emitted format, which now consists of several chunks of BASE64-encoded
data.
client/mysqlbinlog.cc:
Using IO_CACHE to print events instead of directly to file.
Factoring out code to write event header and base64 representation into
separate function.
mysys/mf_iocache2.c:
Correcting name in documentation.
sql/log_event.cc:
Adding class Write_on_release_cache that holds an IO_CACHE and that
will write contents of IO_CACHE to a designated file on destruction.
Changing signature of event printing functions print_header() and print_base64()
to write to IO_CACHE and changing *all* calls in those functions in accordance.
This means that all printing functions now print to an IO_CACHE instead of to a file,
and that the IO_CACHE is then copied to the file.
The print() function have the same signature as before, but since it is
using print_header() and print_base64(), the data will now be printed
to an IO_CACHE and then copied to the file.
Changing row-based replication events to incrementally build one
BINLOG statement for all events making up a statement.
