gpgscm: Allocate small integers in the rodata section.
* tests/gpgscm/Makefile.am (gpgscm_SOURCES): Add new file. * tests/gpgscm/scheme-private.h (struct cell): Move number to the top of the union so that we can initialize it. (struct scheme): Remove 'integer_segment'. * tests/gpgscm/scheme.c (initialize_small_integers): Remove function. (small_integers): New variable. (MAX_SMALL_INTEGER): Compute. (mk_small_integer): Adapt. (mark): Avoid marking objects already marked. This allows us to run the algorithm over objects in the rodata section if they are already marked. (scheme_init_custom_alloc): Remove initialization. (scheme_deinit): Remove deallocation. * tests/gpgscm/small-integers.h: New file.
Allocate small integers from a fixed pool in the rodata section. This
spares us the initialization, and deduplicates integers across
different processes. It also makes the integers immutable, increasing
