libsane-dev lacks sanei.h header required by some scanner drivers

[Bartłomiej Żogała]

After installing libsane-dev in /usr/include/sane/ there are sane.h and saneopts.h files but not sanei.h file which is required by some packages. Eg. Canon DR_2020U driver here http://software.canon-europe.com/software/0045134.asp .

The problems covers more header files, at least: sanei_net.h, sanei_wire.h, sanei_usb.h, config.h, sanei_codec_bin.h, sanei_backend.h, sanei_debug.h, sanei_config.h.

All those are present in include/sane directory of sane-backends git source but not in /usr/include/sane after installing libsane-dev or libsane-extras-dev

Please note that all `sanei*` files are for internal use by the sane-backends package only. These files are *not* intended to be shared in any way outside of the scope of sane-backends.

If third party backends want to reuse some of these files that is their decision and that's fine buty they should include (and maintain) their own copies. The SANE project does not and will not guarantee any kind of API/ABI compatibility for what's in the `sanei*` files.

None of the `sanei*.h` header files belong in a `libsane-dev` package and I suggest to close this bug report as a "Won't fix".
