src/fr_sub.c: Fix bug revealed by tests (wrong sign in imaginary part).

tests/tgeneric_cfc.c: random tests for complex functions of two variables : the first one of type mpfr_t and the second one of type mpc_t; and tests for parameter reuse.
tests/Makefile.am: add tgeneric_cfc.c to EXTRA_DIST and add new tests files.
tests/tfr_div.c tests/tfr_sub.c: use tgeneric_cfc.c
