mysqldump.test fails on few builders.
The new test, added for a bug 12809202, is fundamentally flawed.
It assumes that, when running program 2>&1, lines printed to stderr and stdout, appear in the same order in which they were printed. But as the output is buffered (stdout, at least), this is not the case.
- remove the offending test case
- rewrite it to be correct
- fix mysqldump.c to not buffer stdout (the least desirable solution - fixing a perfectly correct program to satisfy invalid test case assumptions)
