client: add a config option to abort jobs overdue by > X days

[davidpanderson]

Also, instead of checking for overdue results only at startup, do it once a day as well.

Eventually we might want to have this default to e.g. 30 days.

Fixes #2366

@davidpanderson, please fix the build for windows:

"D:\a\boinc\boinc\win_build\sim.vcxproj" (default target) (48) ->
       (Link target) -> 
         app.obj : error LNK2019: unresolved external symbol "public: int __cdecl ACTIVE_TASK::abort_task(int,char const *)" (?abort_task@ACTIVE_TASK@@QEAAHHPEBD@Z) referenced in function "public: void __cdecl ACTIVE_TASK_SET::report_overdue(void)" (?report_overdue@ACTIVE_TASK_SET@@QEAAXXZ) [D:\a\boinc\boinc\win_build\sim.vcxproj]
