Trim list of exported symbols

Description
The list of exported symbols in exempi is rather extensive. E.g. for i386 the list looks like http://qa.debian.org/cgi-bin/mole/seedsymbols/.raw/seedsymbols/libexempi3_i386
A lot of those symbols should probably not be part of the public ABI.
One suggested possibility is to use a sym file for the exported symbols.
