* bignum.c (bignorm): fixed a bug in normalizing negative numbers

reported from Honda Hiroki <hhonda@ipflex.com>.  normalizing
  should not trim preceding zeros from negative numbers.

* ext/socket/socket.c (ruby_getaddrinfo__aix): merged a patch from
  KUBO Takehiro <kubo@jiubao.org> to support AIX.  [ruby-list:40832]

* lib/yaml/rubytypes.rb (Array::to_yaml): merged a patch from
  Tilman Sauerbeck <tilman@code-monkey.de>.  [ruby-core:05055]

* lib/yaml/rubytypes.rb (Hash::to_yaml): ditto.
