Module Name:
afpnp.c
Abstract:
Routines to manage installation of devices via the answer file.
The main entry points are:
CreateAfDriverTable
DestroyAfDriverTable
SyssetupInstallAnswerFileDriver
CountAfDrivers
The rest of the functions are utilities or routines used by outside
callers only in a special case of some sort.

Routine Description:
pGetSelectedSourceDriver finds which answer file driver was selected, if
any.
Arguments:
Drivers - Specifies the answer file driver table, as created by

device must be selected, but not yet installed.
DeviceInfoData - Specifies the device data
Return Value:
A pointer to the answer file driver attributes, or NULL if no answer file
driver was selected for the device.

Routine Description:
SyssetupFixAnswerFileDriverPath calls SetupCopyOEMFile to copy the device
