o Add File to the mUefiDevicePathLibDevPathFromTextTable table so we
don't include 'File()' in the supposed path name. This happens because
of a possible misfeature in the EDK2 code where any path that's not
recognized is treated as a File() node.
o Convert utf8 input into ucs2 output rather than just copying the
utf8 and hoping for the best (no good comes from that).
o Remove bogus comment about needing to add 1. The dummy array already
is length 1, so that's included in sizeof the struct, so there's no
need to add it.

*** 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

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.
