34e38a56b0 - snprintf() returns at most size-1 of the chars printed into
the buffer.  (n == hostlen) also means the buffer length was
  too short.

- Use sdl->sdl_data only when (sdl->sdl_nlen > 0 && sdl->sdl_alen == 0)
  to prevent redundant output.

3cc31a047e Fix t_spawnattr test for attributes handling by posix_spawn(3).
Connect it to the build.

The code assumed that SCHED_* constants form a contiguous set of
numbers, remove the assumption by using schedulers[] array in
get_different_scheduler().  This is no-op on FreeBSD, but improves
code portability.

The selection of different priority used the min/max priority range of
the current scheduler class, instead of the priority to be changed to.
The bug caused the test failure.

Remove duplication of POSIX_SPAWN_SETSIGDEF flag and now unused
duplications of MIN/MAX definitions.

bd6060a1c6 Switch libc from using _sig{procmask,action,suspend} symbols, which
are aliases for the syscall stubs and are plt-interposed, to the
libc-private aliases of internally interposed sigprocmask() etc.

Since e.g. _sigaction is not interposed by libthr, calling signal()
removes thr_sighandler() from the handler slot etc.  The result was
breaking signal semantic and rtld locking.

The added __libc_sigprocmask and other symbols are hidden, they are
not exported and cannot be called through PLT.  The setjmp/longjmp
functions for x86 were changed to use direct calls, and since
PIC_PROLOGUE only needed for functional PLT indirection on i386, it is
removed as well.

The PowerPC bug of calling the syscall directly in the setjmp/longjmp
implementation is kept as is.

842ad8ac0b wordexp(): Stop using the undocumented wordexp builtin.
The functionality of the wordexp builtin is easily replaced using normal
shell code, although performance is slightly worse.

This does not mean that wordexp() will remain shell-independent -- a fully
reliable implementation of WRDE_NOCMD is really only possible using
extensions to the shell, or by adding much of the shell's code to libc.

347a39b4a6 Add support for the arrays in nvlist library.
- Add
  nvlist_{add,get,take,move,exists,free}_{number,bool,string,nvlist,
  descriptor} functions.
- Add support for (un)packing arrays.
- Add the nvl_array_next field to the nvlist structure.
  If an array is added by the nvlist_{move,add}_nvlist_array function
  this field will contains next element in the array.
- Add the nitems field to the nvpair and nvpair_header structure.
  This field contains number of elements in the array.
- Add special flag (NV_FLAG_IN_ARRAY) which is set if nvlist is a part of
  an array.
- Add special type (NV_TYPE_NVLIST_ARRAY_NEXT).This type is used only
  on packing/unpacking.
- Add new API for traversing arrays (nvlist_get_array_next).
- Add the nvlist_get_pararr function which combines the
  nvlist_get_array_next and nvlist_get_parent functions. If nvlist is in
  the array it will return next element from array. If nvlist is last
  element in array or it isn't in array it will return his
  container (parent). This function should simplify traveling over nvlist.
- Add tests for new features.
- Add documentation for new functions.
- Add my copyright.
- Regenerate the sys/cddl/compat/opensolaris/sys/nvpair.h file.
