[mdt-ocl.dev] Dead branches

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi

I've finally pushed the code generated validation code for expression 
arguments which I started working on over a year ago; required accurate 
modeling of generic types. Encouragingly/disappointingly it revealed 0 
new bugs in the UML 2.5 XMI.

As a result I've deleted quite a few branches, so delete your local 
remote tracking branches and fetch from upstream to restore those that 
remain.

I killed one vintage merged releng branch. bug/349300 can probably go too.

    Regards

        Ed
