fix new gcc 8.1 warnings

  use vsyscall for time on x86_64 instead of wrapping gettimeofday (Nikola Vladov)
  CPU affinity support (Indan Zupancic)

  finally add stdout tty detection and turn off linewise buffering if !tty

  reading from stdin used to flush stdout.  Now it only does that
    if stdin is a tty.

  update syscalls
  lots of fixes from Markus FX Oberhumer:
    * better signal handling error detection
    * setjmp.S on i386
    * getenv on i386
    * sys/stat.h -malign-double fix
    * update fcntl.h for MIPS to 2.6.13 version
    * jmp_buf is 40*8 instead of 58*8 on ppc64.
    * This patch fixes the section of the TOC entries on ppc64
    * libstdc++ updates for gcc 4
    * remove cstddef and cwchar (no longer needed)
    * int -> ssize_t for read and write
    * sigjmp.c: __mask_was_saved was not set in all cases!
    * another round of ILP64 cleanups

  remove new gcc4 signedness warnings

- some more stdio unlocked functions and cleanup with the cancel-points
- "new"-internal pthread_mutex_{un,}lock functions

some more _unlocked functions

  the overflow checking in strtou?ll? was broken in some cases.
    Unfortunately, correct overflow checking enlarged the routine by 20%.
    (reported by Manuel Novoa III)
  two stdio bug fixes (also reported by Manuel Novoa III)

ok now fread is working in a pipe...

remove more warnings

import a few more Uwe Ohse bug reports

make ungetbuf an unsigned char (forgot to cast back to unsigned in
fgetc_unlocked).  This was the bug that broke bzip2!  Hooray!

removed "some" warnings ...

enabled a few more obscure gcc warnings and started adding fluff code to
silence them.

so a LITTLE change of stdio.... (urg...)
added some weak aliases to assembler returns :) that are always present.

fix a lot of bugs ;)

remove a few warnings and add a ton of new i386 libmath routines from
Frank Klemm ;)

ahm... hadn't commited this (needed for __v_printf)

make stdio compile again and strcpy a teeny bit smaller

Today was the day (aeh yesterday was the start now the stop...) I have
implemented all the *scanf functions (yes even sose crapy stdio variants..)
Now I... WE have to test them :) (other should have FUN too ...)

ugh, touched all stdio and ripped out the non-ungetc and unbuffered
modes.  Did some ELF weak symbol trickery to make `puts("foo")' not
reference the whole stdio crap.

setfsuid, setfsgid syscalls.

add threadsafe.sh hack.

forgot to remove two files.

finalize THREAD_SAVE renaming, include libpthread in standard targets
for each platform.

typo, WANT_THREAD_SAVE -> WANT_THREAD_SAFE

added ungetc (yuck!)

several stdio fixes courtesy to the S-Lang test suite.

usleep fixed.
reorganized interleaved read/write seeking in stdio.

popen and pclose!  Whee!  diet libc can not link slsh (small interpreter
from S-Lang)

Implemented linker warnings!  Woohoo!
Added linker warnings to a couple of dangerous or bloaty functions.

files where missing (?)
