REF: https://bugzilla.tianocore.org/show_bug.cgi?id=704
For root directory, the FID (File Identifier Descriptor) pointer is
accessible through PRIVATE_UDF_FILE_DATA.Root, whereas non-root
directory and regular files, their FIDs are accessible through
PRIVATE_UDF_FILE_DATA.File.
In UdfSetPosition(), the FID was retrieved through
PRIVATE_UDF_FILE_DATA.File, hence when calling it with a root directory,
PRIVATE_UDF_FILE_DATA.File.FileIdentifierDescriptor would be NULL and
then dereferenced.
This patch fixes the NULL pointer dereference by calling _FILE() to
transparently return the correct UDF_FILE_INFO * which points to a valid
FID descriptor of a specific file.

When building the driver for DEBUG/RELEASE, GCC48/GCC49 warn about
ReadFile() possibly using "BytesLeft" without initializing it first.
This is not the case. The reads of "BytesLeft" are only reachable if
(ReadFileInfo->Flags == READ_FILE_SEEK_AND_READ). But, in that case, we
also set "BytesLeft" to "ReadFileInfo->FileDataSize", near the top of the
function.
Assign "BytesLeft" zero at the top, and add a comment that conforms to the
pending Coding Style Spec feature request at
<https://bugzilla.tianocore.org/show_bug.cgi?id=607>.

The ECMA-167 standard (3rd Edition, June 1997) reserves values 4 through 7
in the ICB.Flags[2:0] bit-field for future standardization; see "14.6 ICB
Tag" / "14.6.8 Flags (RBP 18)".
https://www.ecma-international.org/publications/standards/Ecma-167.htm
The
switch (RecordingFlags)
statement in the ReadFile() function handles all the standard values,
using the constants of the UDF_FE_RECORDING_FLAGS enum type. However, the
reserved values are not caught with a "default" case label, which both
breaks the edk2 Coding Style Spec, and leaves the Status variable
un-initialized, before we return Status under the Done label.
Set Status to EFI_UNSUPPORTED if we encounter a reserved value.

In the expression

the second expression is only evaluated if the first expression is false.
If the first expression is false, i.e.,
RemainderByMediaBlockSize == 0
then UDF_LOGICAL_SECTOR_SIZE is a whole multiple of "Media->BlockSize",
which implies
UDF_LOGICAL_SECTOR_SIZE >= Media->BlockSize.
Therefore whenever

In the ReadFile() function, if "RecordingFlags" is INLINE_DATA, then we
cover the following values of "ReadFileInfo->Flags":
- READ_FILE_GET_FILESIZE
- READ_FILE_ALLOCATE_AND_READ
- READ_FILE_SEEK_AND_READ
We don't do anything (just proceed to the end of the function) if
"ReadFileInfo->Flags" is anything else.
In reality the above three values cover the domain of the
UDF_READ_FILE_FLAGS enum type fully, and "ReadFileInfo->Flags" is only
ever set internally to UdfDxe. Therefore any other flag value would be a
bug in UdfDxe.
ASSERT() specifically that "ReadFileInfo->Flags" has been set correctly,
so that the reader is not left wondering what happens if none of the enum
constants match.

The cause is that after executing the second reconnect action, DiskIo
immediately returns EFI_NO_MEDIA in function DiskIo2ReadWriteDisk() when
checking the media information. However, at this time, the media
information does not get updated by the ScsiDisk driver. Therefore, DiskIo
driver should left the no media check to ScsiDisk driver.
Generally, the media changed and media write protect check should also be
left to lower-level device driver. Thus, these two checks in function
DiskIo2ReadWriteDisk() are also removed.

2. Add MODULE_UNI_FILE file that contains the localized Abstract and Description of a module.
a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion.
c. There will be an associated update to UPT in BaseTools to produce MODULE_UNI_FILE and associated UNI file during UDP installation that performs the XML -> INF conversion.
3. Add Module Extra UNI file that provides the localized Name of a module.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.
