(subsystem) command-line flags.

Darren Tucker f5fc6a4c34 Add configure-time detection for SSH_TIME_T_MAX.
Should fix printing cert times exceeding INT_MAX (bz#3329) on platforms
were time_t is a long long.  The limit used is for the signed type, so if
some system has a 32bit unsigned time_t then the lower limit will still
be imposed and we would need to add some way to detect this.  Anyone using
an unsigned 64bit can let us know when it starts being a problem.

dtucker@openbsd.org 4bdf7a0479 upstream: Replace SIGCHLD/notify_pipe kludge with pselect.
Previously sshd's SIGCHLD handler would wake up select() by writing a
byte to notify_pipe.  We can remove this by blocking SIGCHLD, checking
for child terminations then passing the original signal mask through
to pselect.  This ensures that the pselect will immediately wake up if
a child terminates between wait()ing on them and the pselect.

In -portable, for platforms that do not have pselect the kludge is still
there but is hidden behind a pselect interface.

Darren Tucker c9f7bba2e6 Move closefrom() to before first malloc.
When built against tcmalloc, tcmalloc allocates a descriptor for its
internal use, so calling closefrom() afterward causes the descriptor
number to be reused resulting in a corrupted connection.  Moving the
closefrom a little earlier should resolve this.  From kircherlike at

djm@openbsd.org ea9e45c89a upstream: Switch ssh_config parsing to use argv_split()
This fixes a couple of problems with the previous tokeniser,
strdelim()

1. strdelim() is permissive wrt accepting '=' characters. This is
  intended to allow it to tokenise "Option=value" but because it
  cannot keep state, it will incorrectly split "Opt=val=val2".
2. strdelim() has rudimentry handling of quoted strings, but it
  is incomplete and inconsistent. E.g. it doesn't handle escaped
  quotes inside a quoted string.
3. It has no support for stopping on a (unquoted) comment. Because
  of this readconf.c r1.343 added chopping of lines at '#', but
  this caused a regression because these characters may legitimately
  appear inside quoted strings.

The new tokeniser is stricter is a number of cases, including #1 above
but previously it was also possible for some directives to appear
without arguments. AFAIK these were nonsensical in all cases, and the
new tokeniser refuses to accept them.

The new code handles quotes much better, permitting quoted space as
well as escaped closing quotes. Finally, comment handling should be
fixed - the tokeniser will terminate only on unquoted # characters.
