ad88f982c0 Add some size checks when accessing Drives[], mostly needed when DOS_DRIVES is not set to 26, make size parsing not go outside the target array. 
Let's not try to assign a drive in the switchlist to a too high number.
Don't access imagelist for drives >D when unmounting.

4a1ef4d3d7 Refine stack overflow and underflow for the fpu a bit. 
Overflow is still treated as Exit.
Underflow is ignored in release mode as it happens every now and then and doesn't seem to cause issues if ignored, thus restoring 0.74 behaviour.

202bfa1155 New Drive type: overlay. 
When active, this drive redirects new and changed files to a different location.
The files in the overlay and normal drive are merged on startup and kept up to date when the game changes something. 
Files in the overlay are priotizedi, if they exists, above the normal files. 
The drive will switch to an overlayed version of the file on the first write! (Not when opening the file in write-mode).
The overlay is capable of creating missing directories.

With the help of DBOVERLAY files, the drive keeps track of files that are present in the normal directory but deleted by the game. 
All changes are preserved between sessions. 

Current design principles/limitations/requirements:
1) All directories that can be used for saving, must exist already in the base before mounting. (they will be created by DOSBox if missing in the overlay)
2) All filenames inside the overlay directories are UPPERCASE and conform to the 8.3 standard except for the special DBOVERLAY files.
3) To keep point 1 valid at all times, support for creating/renaming/removing directories has been disabled.

Thanks for the help GOG.

59805112d9 Use record size of 128 if it is 0 in the FCB when calling INT 21 AH=23 (fixes bug #433). 
Set record size to 128 if it is 0 in the FCB when calling any FCB read/write function (ripsaw).
Fixes for acad 10:
- Add missing reference counting when the file is already open when calling FCB_Open, so that acad which uses FCBs and normal handles on the same file works better.
- Remove FCBs being added to the PSP filetable and rewrite most functions to support this change. This way acad won't run out of temporary (fcb) files when low on memory.
