- if pw is NULL and oldpw is not NULL then the oldpw is deleted
- if pw->pw_name != oldpw->pw_name but pw->pw_uid == oldpw->pw_uid

add new gr_* functions so now gr_util API is similar to pw_util API,
this allow to manipulate groups in a safe way.

conversion between enum desdir/desmode from include/rpc/des.h, and enum
desdir/desmode from include/rpcsvc/crypt.x. These are actually
different enums, with different value names, but by accident the integer
representation of the enum values happened to be the same.

warning by an older version of gcc, but I could not reproduce it with
any version of gcc that I have access to.

versions of pthread_md.h have a special case of dereferencing a null
pointer. Clang warns about this with:
In file included from lib/libthr/arch/i386/i386/pthread_md.c:36:
lib/libthr/arch/i386/include/pthread_md.h:96:10: error: indirection of non-volatile null pointer will be deleted, not trap [-Werror,-Wnull-dereference]
return (TCB_GET32(tcb_self));

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
lib/libthr/arch/i386/include/pthread_md.h:96:10: note: consider using __builtin_trap() or qualifying pointer with 'volatile'
Since this indirection is done relative to the fs or gs segment, to
retrieve thread-specific data, it is an exception to the rule.
Therefore, add a volatile qualifier to tell the compiler we really want
to dereference a zero address.

__noreturn macro and modify the other exiting functions to use it.
The __noreturn macro, unlike __dead2, must be used BEFORE the function.
This is in line with the C and C++ specifications that place _Noreturn (c1x)
and [[noreturn]] (C++11) in front of the functions. As with __dead2, this
macro falls back to using the GCC attribute.
Unfortunately, clang currently sets the same value for the C version macro
in C99 and C1x modes, so these functions are hidden by default. At some
point before 10.0, I need to go through the headers and clean up the C1x /
C++11 visibility.

vs. the comment documented "If we are working with a privileged socket,
then take only one attempt". Make the code match.
Furthermore, critical privileged applications that [over] log a vast amount
can look like a DoS to this code. Given it's unlikely the single reattempted
send() will succeeded, avoid usurping the scheduler in a library API for a
single non-critical facility in critical applications.

Without this, code calls pthread_once(), receives a return value of
success, and thinks that the passed function has been called.

userspace processes. ffclock_getcounter() returns the current value of the
kernel's feed-forward clock counter. ffclock_getestimate() returns the current
feed-forward clock parameter estimates and ffclock_setestimate() updates the
feed-forward clock parameter estimates.

non-null passphrase will successfully unlock the key.
To address this, try at first to load the key without a passphrase.
If this succeeds and the user provided a non-empty passphrase *or*
nullok is false, reject the key.
