commit a68075908a37850918ad96b056acc9ac4ce1bd90 upstream.
The comparisons should be >= since 0x800 and 0x80 require an additional bit
to store.
For the 3 byte case, the existing shift would drop off 2 more bits than
intended.
For the 2 byte case, there should be 5 bits bits in byte 1, and 6 bits in
byte 2.

commit 73500267c930baadadb0d02284909731baf151f7 upstream.
This adds ucs2_utf8size(), which tells us how big our ucs2 string is in
bytes, and ucs2_as_utf8, which translates from ucs2 to utf8..

We want to be able to use the utf16 functions that are currently present
in the EFI variables code in platform-specific code as well. Move them to
the kernel core, and in the process rename them to accurately describe what
they do - they don't handle UTF16, only UCS2.
