Description:
The mysqltest binary has an internal hard-coded limit of 128 open connections. Unfortunately, in situations where we try to convert massive concurrent test runs into MTR test cases, it is possible to easily exceed that number.

Please increase the limit to 5120. I tried with 1024, and the binary compiled OK and worked as expected for my purposes.

How to repeat:
N/A

Instead of increasing the hard-coded limit all the way up, I've coded an optional argument; default remains 128.  Do you have a concrete test case to try it with, or should I just construct something?

Noted in 5.5.3, 6.0.14 changelogs.

mysqltest has a new --max-connections option to set a higher number 
of maximum allowed server connections than the default 128. This
option can also be passed via mysql-test-run.pl.

Setting report to Need Merge pending push into 5.1.x, Celosia.
