DOS 5+ TASK SWITCHER - FREE SWITCHER ID

AX = 4B04h
BX = switcher ID
ES:DI -> task switcher entry point (see #02819)

Return:
AX = 0000h BX = status 0000h successful other error (invalid ID or ID not allocated)

Notes: Called by a task switcher when it exits, unless it was the first loaded and is providing the support for AX=4B03h and AX=4B04h. The task switcher providing the identifiers may call the terminating task switcher's entry point as needed. This call is available from within DOSSHELL even if the task switcher is not installed. This call is supported by PC Tools v8+ CPTASK, but appears to return sucessfully no matter which ID is given
