Subject: Change interfaces of evarconv as suggested by Enrico.

Now the main functions are unify (solves the problems entirely) and
unify_delay and unify_leq (which might leave some unsolved constraints).

Deprecated the_conv_x and the_conv_x_leq (which were misnommers as they
do unification not conversion).
