[PATCH v6 0/6] read-only UDF file system support

[Paulo Alcantara <pcacjr@zytor.com>]

Hi,

This series introduces read-only UDF file system support in EDK2. As
Laszlo (or Red Hat) seemed to be interested in such support, I'm posting
it again after ~3 years.

The idea is not replacing the default FAT file system, nor breaking any
existing file system support, but extending EDK2 with a new file system
that might be useful for some people who are looking for specific file
system features that current FAT doesn't support.

Originally the driver was written to support UDF file systems as
specified by OSTA Universal Disk Format Specification 2.60. However,
some Windows 10 Enterprise ISO (UDF bridge) images that I tested
supported a revision of 1.02 thus I had to rework the driver a little
bit to support such revision as well.

v2:
 - Rework to _partially_ support UDF revisions <2.60.
 - Use existing CDROM_VOLUME_DESCRIPTOR structure defined in Eltorito.h
   instead of creating another one (UDF_VOLUME_DESCRIPTOR).
 - Fixed UdfDxe to correctly follow UEFI driver model.
 - Use HARDDRIVE_DEVICE_PATH instead of a vendor-defined one.
 - Detect UDF file systems only in PartitionDxe, and let UdfDxe driver
   check for specific UDF device path to decide whether or not install
   SimpleFs protocol.
 - Place MdePkg changes in a separate patch.
v3:
 - Install UDF partition child handles with a Vendor-Defined Media
   Device Path.
 - Changed UdfDxe to check for Vendor-Defined Media Device Paths with a
   specific UDF file system GUID when determining to whether or not
   start the driver.
 - Removed leading TAB chars in some source files identified by
   PatchCheck.py tool.
v4:
 - Added missing R-b's.
v5:
 - Fixed OVMF IA32 build.
 - Fixed a typo in UdfDriveBindingStop() ("This" -> "SimpleFs") which
   broke retrieval of private fs data from SimpleFs protocol --
   identified by 'reconnect -r' command in UEFI shell.
v6:
 - Fixed a bug in UdfRead() that'd pontentially break in ARM or IA32
   by allowing caller to read more than 4GiB of data
   (i.e. BufferSize pointer is dereferenced as an UINT64 * and it's
    followed by 4 bytes that are nonzero).
