--max_granted_credit not respected by fallback credit calculation mechanism

[dhardy]

We (malariacontrol.net) recently had a problem where PFC was too high for some hosts (or in some cases still is). This has resulted in credits being calculated using an alternate mechanism:

        if (pfc > wu.rsc_fpops_bound) {
            log_messages.printf(MSG_NORMAL,
                "[credit] PFC too high: %f\n", pfc*COBBLESTONE_SCALE
            );
            pfc = wu_estimated_pfc(wu, app);
        }

Unfortunately in our case this wasn't always correct. The attached patch at least allows the --max_granted_credit mechanism to still limit the credit granted.

patch against boinc/sched/credit.cpp

[davea]

(In [22793]) - client, acct manager protocol:

allow <no_cpu>, <no_cuda> and <no_ati> bools within <account> in reply message. They suppress work fetch for that resource type from that project.

• scheduler:

check max_granted_credit after wu.rsc_fpops_bound, so that max_granted_credit will be enforced even if wu.rsc_fpops_bound is absurdly high Fixes #1034. From Diggory Hardy.
