Core: Add a libusb_strerror() function

This patch adds the much requested libusb_strerror() function, taking into
account all issues people raised wrt previous attempts.

Criteria / Decisions underlying this implementation:
- Must support translated messages
- Must not use gettext as that does not work well in combination with Windows
 (when building with Visual C, or for Windows CE)
- API compatible with FreeBSD and various patched libusb-s floating around
- KISS:
 - Do not add any (other) library dependencies
 - Do not try to deal with message encodings (iconv), simply always return UTF-8
   making encoding the problem of the application using libusb_strerror.
 - Defaults to English, so apps which don't want translated messages,
   don't need to do anything special
 - Defaults to English (with pure ASCII messages), so apps which don't
   call libusb_setlocale() don't need to worry about encoding
