Remove Safe_marshal

Safe_marshal was using intermediate strings that are subject to
Sys.max_string_length limitation. Use directly binary channel-oriented
functions instead. This is a fix for bug #2471. Remark: this might
reduce robustness w.r.t. noise in the communication channel.

AFAIK, the original purpose of Safe_marshal was to work around a bug
on Windows... this should be investigated further.
