Bracket the kern.vnode sysctl in #ifdef notyet because it results
in massive locking issues on diskless systems.
It is also not clear that this sysctl is non-dangerous in its
requirements for locked down memory on large RAM systems.
There does not seem to be practical use for it and the disabled routine
does not work anyway.

Add mostly glibc and msl compatible secure_getenv. Return NULL if
issetugid() indicates the process is tainted, otherwise getenv(x). The
rational behind this is the fact that many Linux applications use this
function instead of getenv() as it's widely consider a, "best

The current name was a historical curiosity that started when init array
support was added, and then the file appeared a convenient place for the
addition of the MI common code to csu. It is now referenced by name in
single place and the rename is easy, so do it.

Why? Most trivial point, it shaves around 600 bytes from the dynamic
binaries on amd64. Less trivial, the removed code is no longer part of
the ABI, and we can ship updates to it with libc updates. Right now most
of the csu is linked into the binaries and require us to do somewhat
tricky ABI compat when it needs to change. For instance, the init_array
change would be much simpler and does not require note tagging if we
have init calling code in libc.
This could be improved more, by splitting dynamic and static
initialization. For instance, &_DYNAMIC tests can be removed then.
Such change, nonetheless, would require building libc three times.
I left this for later, after this change stabilizes, if ever.

have a mostly complete (missing pipes) 4th edition C rewrite where
profil system call number is reserved, but it's not implemented (it's in
the manx section for things that apeared to have been in 3rd edition but
weren't yet part of the reimplemented 4th edition). The 5th edition

Casting to int truncates size on some platforms, resulting swab not
copying all the data. Cast len to size_t to avoid right shifting a
signed value: we know here it's > 0, so we can safely cast it w/o losing
precision.
In addition, be more careful with signedness of char pointers and

Under Linux to sched_[g|s]etaffinity() functions the value returned from a call
to gettid(2) (thread id) can be passed in the argument pid. Specifying pid as 0
will set the attribute for the calling thread, and passing the value returned
from a call to getpid(2) (process id) will set the attribute for the main thread
of the thread group.
Native cpuset(2) family of system calls has "which" argument to determine how
the value of id argument is interpreted, i.e., CPU_WHICH_TID is used to pass
a thread id and CPU_WHICH_PID - to pass a process id.
For now native sched_[g|s]etaffinity() implementation is wrong as uses "which"
CPU_WHICH_PID to pass both (process and thread id) to the kernel. To fix this
adding a new "which" CPU_WHICH_TIDPID intended to handle both id's.

Cast char's through unsigned char before storing as an integer in
xdr_char(), this ensures that the encoded form is consistently not
sign-extended following Open Solaris's example.
Prior to this change, platforms with signed chars would sign extend
values with the high bit set but ones with unsigned chars would not
so 0xff would be stored as 0x000000ff on unsigned char platforms and
0xffffffff on signed char platforms. Decoding has the same
result for either form so this is a largely cosmetic change, but it
seems best to produce consistent output.
