David Anderson dd16170fc1 - scheduler: the p_fpops value reported by clients can't be trusted.
Some credit cheats (e.g. with credit_by_runtime) can be done
    by reporting a huge value.
    Fix this by capping the value at 1.1 times the 95th percentile
    of host.p_fpops, taken over active hosts.

David Anderson b2451544e1 - server: change the following from per-host to per-(host, app version):
- daily quota mechanism
    - reliable mechanism (accelerated retries)
    - "trusted" mechanism (adaptive replication)
- scheduler: enforce host scale probation only for apps with
    host_scale_check set.
- validator: do scale probation on invalid results
    (need this in addition to error and timeout cases)
- feeder: update app version scales every 10 min, not 10 sec
- back-end apps: support --foo as well as -foo for options

Notes:
- If you have, say, cuda, cuda23 and cuda_fermi plan classes,
    a host will have separate quotas for each one.
    That means it could error out on 100 jobs for cuda_fermi,
    and when its quota goes to zero,
    error out on 100 jobs for cuda23, etc.
    This is intentional; there may be cases where one version
    works but not the others.
- host.error_rate and host.max_results_day are deprecated

TODO:
    - the values in the app table for limits on jobs in progress etc.
        should override rather than config.xml.

Implementation notes:
scheduler:
    process_request():
        read all host_app_versions for host at start;
        Compute "reliable" and "trusted" for each one.
        write modified records at end
    get_app_version():
        add "reliable_only" arg; if set, use only reliable versions
        skip over-quota versions
    Multi-pass scheduling: if have at least one reliable version,
        do a pass for jobs that need reliable,
        and use only reliable versions.
        Then clear best_app_versions cache.
    Score-based scheduling: for need-reliable jobs,
        it will pick the fastest version,
        then give a score bonus if that version happens to be reliable.
    When get back a successful result from client:
        increase daily quota
    When get back an error result from client:
        impose scale probation
        decrease daily quota if not aborted
Validator:
    when handling a WU, create a vector of HOST_APP_VERSION
        parallel to vector of RESULT.
        Pass it to assign_credit_set().
        Make copies of originals so we can update only modified ones
    update HOST_APP_VERSION error rates
Transitioner:
    decrease quota on timeout

David Anderson 12eb6057e5 - client, Mac: don't do res_init(). It causes a crash.
- client (Unix): if client crashes while benchmark processes are going,
    make sure they detect this and exit.
- back-end programs: remove hardwired assumptions about
    what directory they run in, and hence where config.xml is.
    E.g., daemons look for it in "..", others expect it in current dir.
    New approach: all the programs look for the project dir as follows:
    1) the environment var BOINC_PROJECT_DIR, if defined
    2) the current dir, if config.xml is there.
    3) else ".."
    This means you can run programs in either proj/bin/ or proj/,
    or (using BOINC_PROJECT_DIR) you can keep executables
    outside of the project dir.

Eric J. Korpela 8f3abcc835 - Added checks for net/*.h, arpa/*.h, netinet/*.h and code to figure out
which of those files to include
    - Modified MAC address check to work on some non-Linux unixes.
      (mac_address.cpp)
    - Added suggested change to "already attached to project" checking.
      (ProjectInfoPage.cpp)
    - changed includes of standard c header files to their c++ equivalents
      (i.e. replaced <stdio.h> with <cstdio>) for namespace protection.
    - replaced "using namespace std;" with more explicit "using std::function" in
      several files.
    - Fixed bug in checking whether the os is OS/2 and added conditional OS_OS2
      to the build environment. (boinc_platform.m4,configure.ac)
    - Changed build environment to not use -nostandardlibs unless we are using
      G++ and static linkage is specified. (configure.ac)
    - Added makefiles and package building files for solaris CSW package manager.
    - Fixed bug with attempting to find login name using logname. (configure.ac)
    - Added ifdef HAVE_* protection around some include files commonly found in
      sys.
    - Added support for unified binary for x86_64/i686-pc-solaris.
      (cs_platforms.cpp)
    - generate_host_cpid() now uses MAC address on non-linux unix.
      (hostinfo_network.cpp)
    - Macro BOINC_SET_COMPILE_FLAGS now doesn't check gcc only flags on non-gcc
      compilers. (boinc_set_compile_flags.m4)
    - Library compiles no longer depend upon the library extension or require
      the library to be prefixed with lib.
    - More fixes for fcgi builds.
    - Added declaration of "struct ether_addr" and ether_ntoa().  Have not yet
      implemented ether_ntoa() for machines that don't have it, or where it is
      buggy.  (unix_util.h)
    - Added FCGI::perror() which calls FCGI_perror(). (boinc_fcgi.{h,cpp})
    - Fixed library Makefiles so that all required headers get installed.
