shmem_ptr and shmem_team_ptr prototype does not exactly match spec API prototype

[markbrown314]

shmem_ptr and shmem_team_ptr prototype does not match spec API description:

This is a minor nitpick. target should be renamed to dest:

SOS:
shmem_ptr(const void *target, int pe)
shmem_team_ptr(shmem_team_t team, const void *target, int pe)

OpenSHEM spec:
void *shmem_ptr(const void *dest, int pe);
void *shmem_team_ptr(shmem_team_t team, const void *dest, int pe);
