New description:
This ticket adds a proper error handler for GLPK (similar to what we
already have for PARI, NTL, ...). It suffices to add
`sig_on()`/`sig_off()` around a GLPK call to get an error message.
Some more cleanup is also done:
1. change the implementation of `MIPSolverException` to just inherit from
`RuntimeError` without any custom implementation.
2. use `MemoryAllocator` in a few places to make some allocations safer.
This branch requires a patch to GLPK, a '''broken''' version of it was
accepted upstream: [http://lists.gnu.org/archive/html/help-
glpk/2015-11/msg00008.html]
