merge r4328 from branch 2.0 to trunk

improvement: to prepare feature 1051, the code to add a single file (works for
the 3 picture types, ie thumb/file/high) has been factorized into a single
add_file function.

bug fixed: when a function not directly called by the API (such as merge_chunks
or the new add_file function) returning a PwgError, it was not stopping the
execution, it just sets the error code/message. Now we don't return PwgError,
we only create one and then exit().
