Add GUI RPC to reset project debts

[Nicolas]

Feature request: Add a GUI RPC to the client to reset project debts. Preferably to set them to an arbitrary value, not only to zero them.

From what I know about debts, they are adjusted so that the sum of them is 0. This adjustment be done immediately after this RPC. However, changing from a positive debt on a single project to 0 would make it go positive again (and bring other projects closer to zero). For this reason, my suggested RPC can set multiple projects at a time, not needing one RPC per project.

Suggested RPC:

<set_debt>
    <project>
        <project_url>http://project1</project_url>
        <long_term_debt>0</long_term_debt>
        <short_term_debt>0</short_term_debt>
    </project>
    <project>
        <project_url>http://project2</project_url>
        <long_term_debt>0</long_term_debt>
        <short_term_debt>0</short_term_debt>
    </project>
</set_debt>

Answer to that would be <success/> like from most "set" RPCs. Note that the client should handle a missing LTD or STD tag (so that the RPC can be used to only change one of them).

I noticed the output of <get_project_status> and <get_state> RPCs already have the debts; so we have a mechanism to "get" them already.

A couple of the possible CPU scheduler modifications will need different things that need to be reset as a group.

Lets you set all of them at once, as suggested by Nicolas Alvarez. fixes #131

Following report on #302, I noticed the RPC isn't working. I tried this with guirpc_debug? turned on, and I saw the core client is sending an empty reply back. No <success/> but no <error> either.

What boinc_cmd? is sending seems to be correct. I looked at the way set_debt expects the XML, and I think it should work with that XML input (although I don't know about the details of the XML parser API). It's strange that it doesn't work but no <error> is returned either.

BOINC client windows_intelx86 5.10.13, RPC seems to be still broken. I will try 5.10.17 later; I was sticking to .13 trying to track down a different problem (AMS-related crash).

[Nicolas]

I don't see any change on the client_state.xml after calling the set_debt RPC. BOINC 5.10.18, Windows.

I don't know when this was fixed, but it definitely works on 5.10.3x.

[Nicolas]

Tracked it down. It was indeed fixed in [13065], but applied to the 5.10 branch in [13211], fix available since 5.10.14.
