Hi Bruno.
José Marchesi reported that the 'list' and 'oset' container data structures
are not really usable in libraries, because they call xalloc_die() when
an out-of-memory condition occurs. An xalloc_die() that calls exit() is
not usable in a library. An xalloc_die() that calls setjmp or throws a C++
exception would leak memory and would leave things in an inconsistent state.
This fixes it, by allowing the user to use alternative functions
(gl_list_nx_create instead of gl_list_create, etc.) that provide an error
indicator return value.
Thank you very much! :)
I updated the libgnupdf code to use the new 'nx' functions, caring
about the returned value.
Just a little-tiny typo fix:
