5a79777b44 Use aux vector to get values for SSP canary, pagesize, pagesizes array,
number of host CPUs and osreldate.

This eliminates the last sysctl(2) calls from the dynamically linked image
startup.

8eb397b4ca Tweak code a bit to be POSIX compatible, when a cancellation request
is acted upon, or when a thread calls pthread_exit(), the thread first
disables cancellation by setting its cancelability state to
PTHREAD_CANCEL_DISABLE and its cancelability type to
PTHREAD_CANCEL_DEFERRED. The cancelability state remains set to
PTHREAD_CANCEL_DISABLE until the thread has terminated.

It has no effect if a cancellation cleanup handler or thread-specific
data destructor routine changes the cancelability state to
PTHREAD_CANCEL_ENABLE.

618102f75f In setusercontext(), do not apply user settings unless running as the
user in question (usually but not necessarily because we were called
with LOGIN_SETUSER).  This plugs a hole where users could raise their
resource limits and expand their CPU mask.

1c0c0dee6b no-op commit to note that the example given in the previous commit is
a very bad one, since the shift does not actually overflow.  This is
a better example (assuming uint64_t = unsigned long long):

  ~0LLU >> 9             =   0x7fffffffffffffLLU
  ~0LLU >> 9 << 10       = 0xfffffffffffffc00LLU
  ~0LLU >> 9 << 10 >> 10 =   0x3fffffffffffffLLU

1938427015 Fix the overflow test. It is possible for the result of an
overflowing shift to be larger than the original value, e.g.

         (uint64_t)1 << 53 = 0x20000000000000
 ((uint64_t)1 << 53) << 10 = 0x8000000000000000

b1567fc88a Simplify expand_number() by combining the (unrolled) loop with the
switch.  Since expand_number() does not accept negative numbers, switch
from int64_t to uint64_t; this makes it easier to check for overflow.

5fdaddea72 - When there is no room for returning the result, nss backend
have to return ERANGE and terminate with NS_RETURN.
- When gethostbyname_r(3) and the friends end with an error,
  set errno to the value nss backend returns, and return errno
  value.

Erwin fired up a ports build a couple of weeks ago and it seems the
following functions are not used by any of the 20k ports we have, which
makes me believe they don't have any purpose. Just remove them.

176b515672 Disable all warnings when building gdtoa. This allows building libc with
clang.
The general idea is that the vendor will not accept our compilation
patches and so disabling the warnings is the best way to go as it makes
future imports bearable.
