monty@mysql.com f5fdf3e87a 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

/**********************************************************************
TODO:
- Do comparison line by line, instead of doing a full comparison of
the text file. This will save space as we don't need to keep many
results in memory. It will also make it possible to do simple
'comparison' fixes like accepting the result even if a float differed
in the last decimals.
- Don't buffer lines from the test that you don't expect to need
again.
- Change 'read_line' to be faster by using the readline.cc code;
We can do better than calling feof() for each character!

Read one "line" from the file
SYNOPSIS
read_line
buf buffer for the read line
size size of the buffer i.e max size to read
DESCRIPTION
This function actually reads several lines an adds them to the
buffer buf. It will continue to read until it finds what it believes
is a complete query.
Normally that means it will read lines until it reaches the
"delimiter" that marks end of query. Default delimiter is ';'
The function should be smart enough not to detect delimiter's
found inside strings sorrounded with '"' and '\'' escaped strings.
If the first line in a query starts with '#' or '-' this line is treated
as a comment. A comment is always terminated when end of line '\n' is
reached.

Converts lines returned by read_line into a query, this involves
parsing the first word in the read line to find the query type.
A -- comment may contain a valid query as the first word after the
comment start. Thus it's always checked to see if that is the case.
The advantage with this approach is to be able to execute commands
terminated by new line '\n' regardless how many "delimiter" it contain.
