156840c249 cttyhack: print detected ctty name when called without parameters
Sometimes there's a need to figure out the controlling tty from a shell
script, for example, to obtain a line for getty. In this case it's easier
to call cttyhack than trying to repeat some of the cttyhack's logic.

8de2e42201 syslogd: work around rename() not renaming hardlinks to themselves
Function log_locally() within the syslogd can potentially lock up when
restarting the daemon after a power loss in case the unplanned shutdown hit the
rename operation during logfile rotation.

While POSIX requires the rename operation to be atomic, many file systems such
as JFFS2 implement the rename operation in 2 steps by linking the new name
followed by unlinking the original name. In case of a power loss during the
rename the system can end up with /var/log/messages and /var/log/messages.0
being 2 hard links to the same file.

When the syslog daemon restarts in such a situation it will rediscover the need
to rotate the log files, however, POSIX also requires that rename does nothing
and reports success in case oldpath and newpath are existing hard links to the
same file. Looping through reopen: by (O_CREAT | O_APPEND), the daemon
eternally reopens the same file without succeeding to rotate.

6464f15ddb udhcpc: on SIGUSR1, limit renew attempts time to 20 seconds; then do total reconfig
Scenario:

1. udhcpc gets lease for 86400 secs and sleeps for 43200 before renew attempt

2. PC gets physically disconnected and connected to another network

3. some phy control software sends SIGUSR1 to renew the lease, SIGUSR2 isn't
used because newly connected network could be the same as before

4. udhcpc sends unicast renew requests until lease timeout fall to 60 sec.
They are ignored by new network dhcp servers

5. udhcpc sends broadcast rebind requests for 60 seconds, which are NAKed
or ignored too

6. udhcpc deconfigs and starting from discover state, gets new lease for the
new network

So, pt.4+5 it could take up to 86400 secs without correct lease, which is
too long and not acceptable.

Second SIGUSR1 will immediately run into deconfig/discover state, which is
not preferable in case of the same subnet replugged.

This patch makes sure after SIGUSR1 timeout is no more than -A NUM
(usually 20 sec). It means that renew will be requested via broadcast,
and if no replies come back, full deconf/reconf cycle will be initiated
in 20 seconds.
