fix: don't call field->val_decimal() if the field->is_null()
because the buffer at field->ptr might not hold a valid decimal value

Documentation of the feature can be found at: http://kb.askmonty.org/en/multi-source-replication/
This code is based on code from Taobao, developed by Plinux
Other things:
- Added new commands: START ALL SLAVES, STOP ALL SLAVES and SHOW FULL SLAVE STATUS
- Almost all usage of 'active_mi' is deleted.
- Added parameter to reset_logs() so that one can specify if new logs should be created.
- Check wildcard match as early as possible for SHOW STATUS. This makes SHOW STATUS like 'xxx' a lot faster and use less mutex
- Made max_relay_log_size depending on master connection.
- Added sys_vars.default_master_connection_basic to fix a failure in sys_vars.all_vars, modified sql_slave_skip_counter_basic to allow session-level settings
- Added commands to mysqladmin: start-all-slaves & stop-all-slaves
- Removed logging of "next log '%s' is currently active | not active"
- Fixed bug in my_vsnprintf() when using positional parameters with length
- Added fn_ext2(), which returns pointer to last '.' in file name
- max_relay_log_size now acts as a normal slave specific variable
- Don't store replication position if innobase_overwrite_relay_log_info is not set
- max_relay_log_size copies it's values from max_binlog_size at startup

Don't write the empty "" connection_name to multi-master.info file. This is handled by the original code.
Create Master_info_index::index_file_names once at init
More DBUG_PRINT
Give error if Master_info_index::check_duplicate_master_info fails
Added start|stop all slaves
sql/rpl_mi.h:

Added the logger service that provides us with the rotating logs.
The plugin SQL_ERROR_LOG added. It logs the errors using the 'logger service'
for the rotating log files.

strings/dtoa.c:
The problem was s2b() multiplying and adding hundreds-of-thousands
of ever smaller fractions.
Introducing new collations:
utf8_general_mysql500_ci and ucs2_general_mysql500_ci,
to reproduce behaviour of utf8_general_ci and ucs2_general_ci
from mysql-5.1.23 (and earlier).
The collations are added to simplify upgrade from mysql-5.1.23 and earlier.
Note: The patch does not make new server start over old data automatically.
Some manual upgrade procedures are assumed.
Paul: please get in touch with me to discuss upgrade procedures
when documenting this bug.

New test cases.
strings/dtoa.c:
Increasing the buffer size slightly made some queries pass without leaks.
Adding Bfree(p51, alloc) fixed the remaining leaks.
Converting the number zero to binary and back yielded the number zero,
but with no digits, i.e. zero precision.
This made the multiply algorithm go haywire in various ways.
include/decimal.h:
Document struct st_decimal_t
mysql-test/r/type_newdecimal.result:
New test case (valgrind warnings)
mysql-test/t/type_newdecimal.test:
New test case (valgrind warnings)
sql/my_decimal.h:
Remove the HAVE_purify enabled/disabled code.
strings/decimal.c:
Make a proper zero, with non-zero precision.
WITH UTF32
The 5.5 version of the UTF32 collation was not enforcing the BMP range that
it currently supports when comparing with LIKE.
Fixed by backporting the checks for the BMP from trunk.
Added a named constant for the maximum character that can have a weight
in the weight table.
