* Replaced the dummy implementations of the <grp.h> and <pwd.h>

functions by ones reading /etc/{group,passwd}.
* Added quasi-standard getpwent_r() and getgrent_r().
* Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf()
  constants.
* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
  the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
  should be on the image (executables: 755, others: 644). Otherwise only
  root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
  HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
  root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
  for adding additional users and groups (by default only root user and
  group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
  features have become available.
* Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used
  a wrong variable name before.
