*** CID 1372598: Null pointer dereferences (FORWARD_NULL)
/lib/libefivar/efivar-dp-parse.c: 3612 in UefiDevicePathLibConvertTextToDeviceNode()
Dereferencing null pointer "FromText".
When ported from Tiano core, I commented this out with an ifdef. That
was in error because we're supposed to fallback to a filepath when
nothing else patches. Instead, restore the original code, but fix
DevPathFromTextFilePath to cope with the conversion to narrow
strings. Also, fix the off-by-one error in the size of the memory it
allocates.
The off by one error is documented in Tiano core bug

Paper over a coverity issue:
*** CID 1372592: API usage errors (BAD_COMPARE)
/lib/libefivar/efivar-dp-parse.c: 2723 in DevPathFromTextiSCSI()
Truncating the result of "strcmp" to "unsigned short" may cause it
to be misinterpreted as 0. Note that "strcmp" may return an integer
besides -1, 0, or 1.
We do this by making StrCmp return either 0 or 1 for equal or
not-equal. There's a bug in the DevPathFromTextiSCSI cast of the
return value and this workaround will fix it without breaking other
users of StrCmp (all of which test for == 0).
https://bugzilla.tianocore.org/show_bug.cgi?id=440 has been filed
upstream to log this issue.

This commit implements the (mostly?) Linux compatible
efidp_format_device_path and efidp_parse_device_path APIs. These are
the only APIs exposed through this library. However, they are built on
code from Tianocore's EDK2 MdePkg. They are brought in as new files
here for reasons described in FreeBSD-update.
Symbol versioning will be introduced to control what's exported from
the EDK2 code.
Some structural changes may be necessary when we move to sharing with
sys/boot/efi.

the same API as the GPL'd version of this library. It implements the common
Linux API for programatically manipulating UEFI environment varibales using
the UEFI Runtime Services the kernel provides. It replaces the old efi
library since it is programmed to a different interface, but retails the
CHAR16 to UTF-8 and vice versa conversion routines. The new name is to match
Linux program's expectations.
