Memory leak in coproc code

[Nicolas]

In coproc.cpp line 192:

        if (strstr(buf, "<coproc_cuda>")) {
            COPROC_CUDA* cc = new COPROC_CUDA;
            int retval = cc->parse(fin);
            if (!retval) {
                coprocs.push_back(cc);
            }
        }

If cc->parse fails, the COPROC_CUDA doesn't get added to the coprocs container, but it's not freed either. In line 198, it goes out of scope, and leaks.

Same a few lines below with COPROC_ATI (thanks to code duplication).

This particular code has been rewritten to avoid the dynamic allocation of COPROC_*
