[PATCH v2 0/2] Refine UDF related codes

[Hao Wu <hao.a.wu@intel.com>]

V2 changes:
For patch
MdeModulePkg/PartitionDxe: Merge the discovery of ElTorito into UDF:

PartitionInstallUdfChildHandles() should return EFI_SUCCESS when either El
Torito feature or UDF support is detected on CD/DVD media.

Previous version of the series only return EFI_SUCCESS when the UDF
support is detected, which may bring issue when only El Torito feature is
supported by a CD/DVD medium. For such case, child handle will be created
but the PartitionDxe driver will close the diskio & device path protocols
on the parent handle.


V1 history:
The series will do the following refinements:
a. Merge the discovery of the El Torito feature on CD/DVD media into the
   detect of UDF;
b. Avoid possible loss track of the allocated buffer pointer in UdfDxe.
