    This implements loading and saving a BOARD, behind the PLUGIN interface.

    The definitions:

    *) a Board Internal Unit (BIU) is a unit of length that is used only internally
       to PCBNEW, and is nanometers when this work is done, but deci-mils until done.

    The philosophies:

    *) BIUs should be typed as such to distinguish them from ints.  This is mostly
       for human readability, and having the type nearby in the source supports this readability.
    *) Do not assume that BIUs will always be int, doing a sscanf() into a BIU
       does not make sense in case the size of the BIU changes.
    *) variables are put onto the stack in an automatic, even when it might look
       more efficient to do otherwise.  This is so we can seem them with a debugger.
    *) Global variables should not be touched from within a PLUGIN, since it will eventually
       be in a DLL/DSO.  This includes window information too.  The PLUGIN API knows
       nothing of wxFrame or globals and all error reporting must be done by throwing
       an exception.
    *) No wxWindowing calls are made in here, since the UI resides higher up than in here,
       and is going to process a bucket of detailed information thrown from down here
       in the form of an exception if an error happens.
    *) Much of what we do in this source file is for human readability, not performance.
       Simply avoiding strtok() more often than the old code washes out performance losses.
       Remember strncmp() will bail as soon as a mismatch happens, not going all the way
       to end of string unless a full match.
    *) angles are in the process of migrating to doubles, and 'int' if used, is
       only shortterm, and along with this a change, and transition from from
       "tenths of degrees" to simply "degrees" in the double (which has no problem
       representing any portion of a degree).

    The legacy file format is being obsoleted and this code will have a short
    lifetime, so it only needs to be good enough for a short duration of time.
    Caching all the MODULEs is a bit memory intensive, but it is a considerably
    faster way of fulfilling the API contract. Otherwise, without the cache, you
    would have to re-read the file when searching for any MODULE, and this would
    be very problematic filling a FOOTPRINT_LIST via this PLUGIN API. If memory
    becomes a concern, consider the cache lifetime policy, which determines the
    time that a FPL_CACHE is in RAM. Note PLUGIN lifetime also plays a role in
    cache lifetime.
