New wrappers to lapack functions should be defined in scipy.lib.lapack.
Eventually we should get rid of lapack wrappers in scipy.linalg.
Grep for flapack_*.pyf.src files to see in which file the signature
for a given lapack function should be inserted.
Btw, scipy.lib.lapack already has wrappers for sygv and hegv functions.
