    Minor cleanup · 110fd564
    Robert Sprowson authored 
    Don't include headers we don't need, add Hdr:HostFS so debug builds work.
Don't pointlessly preserve low registers in finalise handler.
Use Unix style names for LNK.
Typos in docs fixed.
Be consistent about wsptr/WP/wp when referring to the workspace pointer.

    Fix for 26 bit pre filter exit · 848b7109
    Robert Sprowson authored 
    PRM 3-305 says to return with MOVS PC,LR but in the 26 bit case we were not preserving flags.

    [455] Don't call filters for tasks that have quit · 07fa7e20
    Robert Sprowson authored 
    Filter Manager continued to call filters based on their Task ID after they had quit. Now, watch out for Service_WimpCloseDown and disable any matching filters (the filters are retained so that any subsequent legitimate deregister attempt doesn't get an unknown filter error). As only 16 bit Task IDs are stored, define a new flag in b31 to denote a disabled filter - this also means there is a free "no match" when the filter lists are scanned.
The copy filter isn't affected because it doesn't select on Task ID.

FilterMgr.s: New flag to mark a task as having quit
ModHead.s: Listen for Service_WimpCloseDown and check the lists of Task IDs for any matches. Simplify *Filters code with advanced subroutine technology.
SWIs.s: Knock out the "quit" flag when comparing task handles to deregister
Tail.s: Walk a list, mark any matching tasks as having quit

Version 0.29. Tagged as 'Filter-0_29'

    Build fix · fc7abb71
    Robert Sprowson authored 
    Ethusiastic unused header cull removed APCS.<APCS> which is used (only) in the standalone case. Replace singular FunctionEntry/Return with Entry/EXIT which is what is more generally used by the module
