Reviewing new pushed code

- CHAR() now returns binary string as default
- CHAR(X*65536+Y*256+Z) is now equal to CHAR(X,Y,Z) independent of the character set for CHAR()
- Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
  (Some old systems returns ETIME and it's safer to test for both values
   than to try to write a wrapper for each old system)
- Fixed new introduced bug in NOT BETWEEN X and X
- Ensure we call commit_by_xid or rollback_by_xid for all engines, even if one engine has failed
- Use octet2hex() for all conversion of string to hex
- Simplify and optimize code


client/mysqldump.c:
  Simple optimizations of new code
  Indentation fixes

  Removed not needed variable
include/mysql_com.h:
  Made octec2hex() more usable
mysql-test/r/ctype_utf8.result:
  CHAR() now returns binary string as default
mysql-test/r/func_str.result:
  CHAR() now returns binary string as default
mysql-test/r/range.result:
  Added test to verify new introduced bug in NOT BETWEEN X and X
mysql-test/r/user_var-binlog.result:
  CHAR() now returns binary string as default
mysql-test/r/view.result:
  More tests of view rename
mysql-test/t/ctype_utf8.test:
  CHAR() now returns binary string as default
mysql-test/t/func_str.test:
  CHAR() now returns binary string as default
mysql-test/t/range.test:
  Added test to verify new introduced bug in NOT BETWEEN X and X
mysql-test/t/view.test:
  More tests of view rename
mysys/mf_keycache.c:
  Indentation changes
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
mysys/my_os2cond.c:
  Fix to MySQL coding style
  Optimized functions
mysys/thr_lock.c:
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
mysys/thr_mutex.c:
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
server-tools/instance-manager/instance.cc:
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
server-tools/instance-manager/thread_registry.cc:
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
sql/ha_federated.cc:
  Use octet2hex()
sql/ha_ndbcluster.cc:
  Removed not used variable
sql/handler.cc:
  Simplify code
  Use *NONE* instead of 'none' for not existing storage engine
  Ensure we call commit_by_xid or rollback_by_xid for all engines, even if one engine has failed
sql/item.h:
  Remove not needed test for *ref.  (If ref is set, it should never point at 0)
sql/item_func.cc:
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
  Simplify code
  More comments
  Require that last argument to find_and_check_access() is given
  (Made code shorter and faster)
sql/item_strfunc.cc:
  Changed CHAR() to return result in binary collation
  CHAR(X*65536+Y*256+Z) is now equal to CHAR(X,Y,Z) independent of the character set for CHAR()
  
  Bar will shortly add the following syntax:
  CHAR(.... USING character_set)
  and ensure that
  CONVERT(CHAR(....) USING utf8) cuts not legal utf8 strings
  Use ocet2hex()
sql/item_strfunc.h:
  CHAR() now returns a binary string
sql/log_event.cc:
  Use octet2hex()
  Simplify code
sql/parse_file.cc:
  Indentation fixes
  Use for() instead of while()
sql/password.c:
  Make octet2hex() more generally usable by returning pointer to end 0
sql/slave.cc:
  Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()

  Fixed wrong merge
sql/sql_select.cc:
  Fixed new bug for NOT BETWEEN X and X

  Indentation fixed
  Removed DBUG_PRINT that is obvious from context
sql/sql_view.cc:
  Simplify code
sql/unireg.cc:
  Use octet2hex()

sql/sql_manager.cc
