sched/delete_file program wasn't working. It created records on the database but they were never sent to clients. After some sourcecode digging, I found messages for hosts are read and processed on the scheduler only if there is a <msg_to_host> setting on config.xml. This is not documented on project options.

delete_file is storing incorrect data on the msg_to_host database table. Variety and xml fields are empty. This is because the mth structure is cleared after these fields are set, on function delete_host_file. Patch attached.

Additionally, there is extra code to check if -host_id is 'all':

if(!strcmp(argv[++i], "all")) {
    host_id = 0;
}

but some lines below the program exits if host_id == 0. Also, the scheduler has no special code to handle this. The messages will never be sent because host '0' will never communicate. I'm not sure how this would be fixed, since I don't know what was the intended behavior.

In order to do this we need a way for the CC to express alternate platform types to the server scheduler. The agreed upon solution is to include an alternate_platform block with the scheduler request.

Example:

    <platform_name>windows_x86_64</platform_name>
    <alt_platform>
        <name>windows_intelx86</name>
    </alt_platform>

At some future point we should add additional information like how much slower the alternate platform is from the native platform, or if more that one alternate platform is supported which one is preferred.
