jbig2dec: Pass segment numbers as unsigned values to error callback.
According to the JBIG2 specification segments numbers are 32 bit unsigned
integer. Previously any segment numbers larger than INT32_MAX would be passed
as negative numbers.
Some parts of the decoder do not yet know, or do not have access to the
currently decoded segment number, and this needs to be specially indicated.
Therefore jbig2dec appropriates the unlikely segment number 0xffffffff to
indicate an unknown segment number.
This is a change of the public API.
