just a flush_relay_log_info() at the end of CHANGE MASTER
(there was already flush_master_info()).


sql/sql_repl.cc:
  Comments.
  Flush relay-log.info after CHANGE MASTER, or the changes
  to the relay log parameters (relay log name and position, and
  the corresponding master's binlog name and position) will be
  lost if the slave mysqld is shutdown immediately after the 
  CHANGE MASTER (without the slave threads being started).

I extended the task to cleaning error messages, making them look nicer,
and making the output of SHOW SLAVE STATUS (column Last_error) be as complete
as what's printed on the .err file;
previously we would have, for a failure of a replicated LOAD DATA INFILE:
- in the .err, 2 lines:
"duplicate entry 2708 for key 1"
"failed loading SQL_LOAD-5-2-2.info"
- and in SHOW SLAVE STATUS, only:
"failed loading SQL_LOAD-5-2-2.info".
Now SHOW SLAVE STATUS will contain the concatenation of the 2 messages.


sql/log_event.cc:
  Print the default database when replication stops because of an error. Previously, we had:
  "error "Duplicate entry 87987 for key 1", query 'insert into t values(87987)'", ie the db
  was not mentioned, making it hard for cases where the same table name is used in
  several databases.
  Lengthened some error messages (for failing replication of LOAD DATA: mention the table
  and the db).
  Changes so that SHOW SLAVE STATUS reports as complete errors as the .err file.
sql/slave.cc:
  Removed a useless declaration (the rewrite_db() function is already declared in slave.h).
  Added missing ')' in error messages.
  Tried to make error messages look nicer (previously we had
  "do START SLAVE;, error_code=1062"
  now we'll have
  "do START SLAVE; . Error_code=1062".
  This form has been discussed, I agree it's no panacea, but it's still more readable
  like this. To be improved in the future :)

   as requested by PeterZ


support-files/my-innodb-heavy-4G.cnf.sh:
   - heavily reworked the comments and layout as requested by PeterZ

   a node name was changed in manual.texi which resulted in a very large
   ReadMe.txt file, as the generating script could not find the (renamed)
   ending node. Fixed the ending node name in Docs/Makefile.am and the 
   Docs/Support/generate-text-files.pl Perl script to make sure this does
   not happen again (I only discovered this because the Do-pkg script was
   not able to add the ReadMe.txt to the Apple Disk image because it ran out
   of disk space due to the size of the file)


Docs/Makefile.am:
   - Fixed a node name that was changed in manual.texi and resulted in
     the generation of a _very_ large ReadMe.txt file (down to the very end
     of the manual, since the ending node was not found)
Docs/Support/generate-text-files.pl:
   - added a safeguard: if the ending node was not found, abort with an error
     to indicate that the generated text file might be too large (as it would
     contain the whole manual, down from the starting node)
   - made some cosmetical changes

sql/log.cc:
  Part revert of previous patch.
  The reason for adding back 'inited' is that is that we can't be 100 % sure that init_pthread_objects() is called before mysqld dies (for example on windows)
  I removed mutex lock handling in is_open() as the new code didn't have ANY affect except beeing slower.
  Added back checking of is_open() to some functions as we don't want to do a mutex lock when we are not using logging.
