  Reuse some code between simple and UCA collations.

- For simple character sets: from_uni convertion table.
- For UCA: alternative weight arrays.
Use mbminlen instead of MY_CS_NONTEXT

reset mysql->status if there was an error in row reading.

  Put back the ha_innodb.cc source code lines that were accidentally removed in Jan Lindstrom's push yesterday (he used the account heikki@mysql.com)

some reason wasn't included before.
A lot of files cleaned up from #include <assert.h>

exactly it's mapped to "ALTER TABLE t; ANALYZE TABLE t;"

New option --sync-binlog=x (and global settable variable) which will fsync the binlog
after every x-th disk write to it. That is, if in autocommit mode, after every x-th statement
written to the binlog; if using transactions, after every x-th transaction written to the binlog.
x==0 means no fsync. x==1 is the slowest.
There is no test added for this, I have just checked that it works as --sync-binlog=1 dramatically
slows down mysqld.
Made sync-frm a global settable variable.

error messages when a query goes wrong.
Note that from now on, if you run with --slave-skip-error=xx, then nothing will
be printed to the error log when the slave is having this error xx and
skipping it (but you don't care as you want to skip it).

/***********************************************************************
This function stores binlog offset and flushes logs */

requested by Guilhem to ha_innodb.cc and ha_innodb.h.

The bug was caused by error in hash calculation function: it
always returned hash value for last field in a composite key, so 
for keys like (a text, b char(1)) we were always
getting bad hash values.

binlog even if they changed nothing, and a test for this.
This is useful when users use these commands to clean up their master and slave by issuing
one command on master (assume master and slave have slightly different data for some
reason and you want to clean up both).
Note that I have not changed multi-table DELETE and multi-table UPDATE because their
error-reporting mechanism is more complicated.
