An issue was seen in IScsiDxe in NetworkPkg where driver cleanup after
initialization failure was not done right. Bug 1428 was filed in this regard.
As per discussions with Mike, it was also discussed that having UEFILib
provide protocol uninstallation abstraction would help to avoid these
issues in the future. Bug 1429 was found to track this. The first 2 patches
take care of this.

Patch number 1 also simplifies the UEFILib protocol installation and
uninstallation abstraction by adding a helper function doing operations
instead of every public function.

Ashish Singhal (2):
  MdePkg/UefiLib: Abstract driver model protocol uninstallation
  NetworkPkg/IScsiDxe: Use UEFILib APIs to uninstall protocols.
