OS/2 interrupts terminology

[prokushev]

RBIL contains lot of strange and different terminology. For example:
INT 21 - OS/2 v1.1+ Family API - DosQFileInfo
INT 21 - OS/2 v1.1+ Compatibility Box Family API - DosQPathInfo
INT 21 U - OS/2 v1.x FAPI - OS/2 FILE SYSTEM JOIN/SUBST
INT 21 U - OS/2 v2.1+ Virtual DOS Machine - OS/2 API DOS32StartSession
INT 21 U - OS/2 v2.0 - "DosOpen2"
Also lot of different terms in notes, like OS/2 box, OS/2 compatibility box, etc.
I think it is good idea to use only 2 terms:
OS/2 v1.1+ Compatibility Box
OS/2 v2.0 MVDM
Family API, FAPI and so on is not relevant because FAPI not provide these API but uses them in OS/2 DOS emulation.

I personally have no experience with OS/2. So, I cannot speak to just about anything regarding it.

Nor, can I say whether things like OS/2 Box and OS/2 Compatibility Box are the same or different things.

OS/2 1.x versions contains DOS emulation named DOS Box or Compatibility box. It is same name for emulation environment, which support one DOS session.

OS/2 2.0+ contains DOS emulation named Multiple DOS Virtual machines or MVDM.

FAPI or Family API is emulation layer for execution of OS/2 applications on top of DOS 3.

RBIL mention some interrupts as FAPI or Family API. This is totally incorrect. FAPI uses such interrupts under DOS Box, but not provide them.

Also, for OS/2 2.0+ such interrupts only provided by DOSKRNL (paravirtualized DOS kernel) for standard DOS MVDM. If MVDM runs unchanged DOS from floppy or floppy image such interrupts not provided by DOS kernel, but DOS driver FSACCESS.

Personally, I can prepare terminology changes to refer in common terminology, if you interested. Also can provide terminology description.

@prokushev, Are you planning to work on a pull request to update these items?

[prokushev]

Yes. I'll send pull request as fast as will be ready.
