Test case

The 'unicode' annotation in the attached test case does not render properly. I
added it through the default mail application on my iOS11 iphone.
I trade that down to _poppler_goo_string_to_utf8() which assumes UTF16 strings
will always be big endian, while in my test file, a little endian UTF16 string
is used.
I've fixed this by adding 2 new methods to GooString (hasBigEndianBOM()
hasLittleEndianBOM()), but all users of GooString::hasUnicodeMarker() should
probably be audited and handle both types of UTF16 strings unless the pdf specs
mandates big endian strings. Since I'm not familiar at all with the PDF format,
I haven't tried to address this yet.
