[PATCH 0/6] minor test-hashmap fixes

This series started with me fixing the sizeof() mismatch discussed in

  https://public-inbox.org/git/20180214164628.GA907@sigill.intra.peff.net/

but I found a number of minor irritations. Most of them are cosmetic in practice, but I think it's important for test-helper code like this to model best practices, since people are likely to use it as a reference.

  [1/6]: test-hashmap: use ALLOC_ARRAY rather than bare malloc
  [2/6]: test-hashmap: check allocation computation for overflow
  [3/6]: test-hashmap: use xsnprintf rather than snprintf
  [4/6]: test-hashmap: use strbuf_getline rather than fgets
  [5/6]: test-hashmap: simplify alloc_test_entry
  [6/6]: test-hashmap: use "unsigned int" for hash storage
