[Coin-ipopt] MUMPS 'independent' package for use with IPOPT

To seperate the MUMPS build process from the Ipopt build process should 
not be a big problem. Even though the configure of ThirdParty/MUMPS is 
initiated from a COIN base project (e.g., Ipopt or Bonmin), only small 
changes to the configure.ac of MUMPS should be necessary to make it run 
independently. However, all COIN-packages use the common BuildTools 
project which provides autotools macros (BuildTools/coin.m4) that are 
excessively used. Thus, making a MUMPS build system independent of 
everything in coin would require to extract also the necessary pieces 
from the BuildTools project.
