7d14df1a2d Add support for IEE/IEC (and now also SI) power of two notions of
prefixes (Ki, Mi, Gi...) for humanize_number(3).

Note that applications has to pass HN_IEC_PREFIXES to use this
feature for backward compatibility reasons.

a699e14f45 humanize_number(3) multiply the input number by 100, which could cause an
integer overflow when the input is very large (for example, 100 Pi would
become about 10 Ei which exceeded signed int64_t).

Solve this issue by splitting the division into two parts and avoid the
multiplication.

Edward Tomasz Napierala
2bfc50bc4f Add two new system calls, setloginclass(2) and getloginclass(2). This makes
it possible for the kernel to track login class the process is assigned to,
which is required for RCTL.  This change also make setusercontext(3) call
setloginclass(2) and makes it possible to retrieve current login class using
id(1).

35305a8dc1 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.

b6fbd4d50d 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

1035d74025 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

bbb2703b4f 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.

2c8d07a874 Fix a regression that was introduced in r191882.
I changed login_tty() to only work when the application is not a session
leader yet. This works fine for applications in the base system, but it
turns out various applications call this function after daemonizing,
which means they already use their own session.

If setsid() fails, just call tcsetsid() on the current session.
tcsetsid() will already perform proper security checks.

21470ecd91 Remove login(3), logout(3) and logwtmp(3) from libutil.
These functions only apply to utmp(5). They cannot be kept intact when
moving towards utmpx. The login(3) function would break, because its
argument is an utmp structure. The logout(3) and logwtmp(3) functions
cannot be used, since they provide a functionality which partially
overlaps.

Increment SHLIB_MAJOR to 9 to indicate the removal.

5649afd028 Revert (once again, and hopefully for the last time) to flock(2) locks.
The problem with fcntl(2) locks is that they are not inherited by child
processes.  This breaks pidfile(3), where the common idiom is to open
and lock the PID file before daemonizing.

46b303e83d Add tcsetsid(3).
The entire world seems to use the non-standard TIOCSCTTY ioctl to make a
TTY a controlling terminal of a session. Even though tcsetsid(3) is also
non-standard, I think it's a lot better to use in our own source code,
mainly because it's similar to tcsetpgrp(), tcgetpgrp() and tcgetsid().

I stole the idea from QNX. They do it the other way around; their
TIOCSCTTY is just a wrapper around tcsetsid(). tcsetsid() then calls
into an IPC framework.
