BUG#23427 incompatible ABI change in 5.0.26?
   - Use the icheck tool if avaliable and compare the current mysql.h to a version
controlled reference file 

Flush both stdout and stderr before abort'ing mysql_client_test

with error 1 and we are running with --force
The specific "analyze" code is enclosed in a .test file fwich can easily
be modified to be more advanced 

This fixes problem where --replace_result failed in rpl000015 because the MYSQL_TCP_PORT variable was "3306\r"

The vardir trick can only bge used on platforms with native symlinks - otherwise opt_vardir need to be set to default value.

As both ndb and im are components that may be disabled as well as the binaries may not exist. Look for 
their binaries in a separate function and produce test casea failures for the test thet needs these components

This can not be done in run_testcase_start_servers as embedded never starts a server
Add error if mysqld_start is called in embedded mode

- compilation on the Alpha platform was broken because the Alpha-specific code was not updated after replacing the SIGRETURN_FRAME_COUNT constant with a variable

Add function mtr_exe_maybe_exists to look for binaries that is optional
Skip ndb support if it's a binary dist where mysqld supports ndb but there is no ndbd

to a value wich is not our default

commands and go directly to result file processing

The value taken to be shown in SHOW PROCESSLIST is not
initialized when THD is created and will be random for
unauthenticated connections.
  
To the documentor: Random value, instead of NULL, was shown,
in SHOW PROCESSLIST for still non-authenticated connections.

We miss some records sometimes using RANGE method if we have
partial key segments.
Example:
  Create table t1(a char(2), key(a(1)));
  insert into t1 values ('a'), ('xx');
  select a from t1 where a > 'x';
We call index_read() passing 'x' key and HA_READ_AFTER_KEY flag
in the handler::read_range_first() wich is wrong because we have
a partial key segment for the field and might miss records like 'xx'.

Fix: don't use open segments in such a case.

into thinking the escaped % + w was a format specifier
