[Scip] Is there a safe way to setName on Cons and Var after creation

[Tobias Achterberg]

Hi Fergal,

the SCIPconsSetNamePoiter() method is private and you should not use it: it is defined in
cons.h and not in pub_cons.h.

At the moment, there is no way to change a variable's or constraint's name after it has
been created. We should add this functionality for the upcoming SCIP 1.2 release.

SCIP Team: I suggest that you add methods SCIPconsSetName() to pub_cons.h and
SCIPvarSetName() to pub_var.h, which take a const char* as input, free the old name,
allocate new memory (or alternatively: reallocate the name string array), and copy the new
name. Obviously, these methods need to return a SCIP_RETCODE as the memory allocation may
fail.

I was looking into using SCIPconsSetNamePointer and SCIPvarSetNamePointer but apart from leaking the old name I think I need to do some BMSallocBlockMemory call to prevent Asserts from firing (I tried a few things  but nothing works so far). Is this supported and is there a way to get the old pointer and free it as part of the setName steps ?
