getgrouplist.3, insque.3, malloc_info.3, pthread_create.3, tsearch.3, aio.7: Use C99-style declarations for readability
Rather than writing things such as:
struct sometype *x;
...
x = malloc(sizeof(*x));
let's use C99 style so that the type info is in the same line as
the allocation:
struct sometype *x = malloc(sizeof(*x));
