Subject: [PATCH] oshmem: swap fields of oshmem_proc_data_t to prevent padding

previously, the definition was

struct oshmem_proc_data_t {
    int num_transports;
    char * transport_ids;
};

so in 64 bits arch, the compiler would very likely insert a 4 bytes
padding before the two fields in order to have transport_ids aligned
