Subject: Fix for BUG#2083 "EE_ error codes (EE_DELETE, EE_WRITE) end up in the
binlog, making slave stop". The problem was that during execution of the
command on the master, an error can occur (for example, not space left on
device, then mysqld waits and when there is space it completes successfully:
so finally it worked but the error EE_WRITE remains in thd->net.last_errno
and thd->net.last_error). To know if finally the command succeeded, we test
the 'error' variable in every place, and if it shows no failure we reset
thd->net.last_err* using the function THD::clear_error() which is backported
from 4.1. A new test to see if now only real errors get to the binlog (note:
the test uses "rm").
Also a bit of memory free/alloc saving in log_event.cc (do not free the whole
mem_root after every query in the slave SQL thread: we can keep the initial
block of it; which will be freed when the thread terminates).
sql/log_event.cc:
In the slave SQL thread, it's a waste to free the initial block of the mem_root
after every query. We can instead keep it. It will be freed when the thread
terminates (in THD::~THD()).
sql/sql_acl.cc:
clear the error in thd->net.last_errno as there was no error
sql/sql_base.cc:
clear the error in thd->net.last_errno as there was no error
sql/sql_class.h:
Backport of THD::clear_error() from 4.1:
clears the error in thd->net.last_errno
sql/sql_db.cc:
clear the error in thd->net.last_errno as there was no error
sql/sql_delete.cc:
clear the error in thd->net.last_errno as there was no error

sql/sql_parse.cc:

sql/sql_rename.cc:

sql/sql_table.cc:

sql/sql_update.cc:
clear the error in thd->net.last_errno as there was no error
