* sizes.c: New file, a list of prime numbers useful for table sizes.
* priv.h (_ihash_sizes, _ihash_nsizes): Declare.
(_ihash_nextprime): Don't.
* ihash.c (ihash_add): Select sizes from the _ihash_sizes array
instead of using _ihash_nextprime.
* Makefile: Clean up whitespace, reorder all the variable definitions.
(SRCS): Remove primes.c, add sizes.c instead.
(OBJS): Define dynamically.
