conflicts with unixodbc and iodbc

[Bradley Giesbrecht]

While creating unixodbc and iodbc(libiodbc) variants for the mysql- 
connector-odbc port, which I maintain, it became annoying to have to  
uninstall/install unixodbc and libiodbc.

I believe I have successfully moved the conflicting files for unixodbc  
and libiodbc into lib/${name}, include/${name} and share/${name}
My tests with mysql-connector-odbc after this change indicate success.

Checking for effected ports reveals a relatively short list of ports  
that would need to be updated.
find /opt/local/var/macports/sources/svn.macports.org/trunk/dports - 
name Portfile | xargs grep "unixodbc\|iodbc"

x11/qt4-x11

Some of these ports do not have variants for unixodbc and/or iodbc  
there by making them un-resolvable conflicts.

It's easy enough for me to conflict unixodbc and iodbc variants in  
myslq-connector-odbc.

I interested if others think it is worth fixing the conflict between  
unixodbc and iodbc.

Comments welcomed.
