mpi: Introduce 4 user flags for gcry_mpi_t.
* src/gcrypt.h.in (GCRYMPI_FLAG_USER1, GCRYMPI_FLAG_USER2)
(GCRYMPI_FLAG_USER3, GCRYMPI_FLAG_USER4): New.
* mpi/mpiutil.c (gcry_mpi_set_flag, gcry_mpi_clear_flag)
(gcry_mpi_get_flag, _gcry_mpi_free): Implement them.
(gcry_mpi_set_opaque): Keep user flags.
--
The space for the flags in the MPI struct is free and thus we can help
applications to make use of some flags. This is for example useful to
indicate that an MPI needs special processing before use.
