768153bf8c mdev: add -v to increase log verbosity
If logging to stderr and/or syslog the -v option can be given one or
more times to increase the log verbosity. If mdev is used as hotplug
helper the log level is fixed set to 2 if mdev.log is found an appended
because there is no possiblity to pass arguments to the hotplug helper.

e9003caf6d mdev: add syslog logging mode
If mdev is run as daemon it should be possible to forward the debug
messages to syslog. This feature might be useful if mdev is run with -s
during boot too. OTOH it makes no sense for the daemon to log to
mdev.log. This can be handled by a syslog daemon way better. If the
daemon stays in the foreground due to -f, the messages are still written
to stderr as before.

d560030548 mdev: re-initialize if uevent messages were lost
If the netlink read() failed with ENOBUFS we know that we have missed at
least one message due to a socket receive buffer overrun. The only way
how to recover is to drop the old socket, open a fresh one and make a
cold-plug scan of the current system state.

3cd55d49a2 mdev: increase netlink buffer sizes
The socket receive buffer turned out to be too small for real world
systems. Use the same size as udevd to be on the safe side. As this is
just a limit and the memory is not allocated by the kernel until really
needed there is actually no memory wasted.

This patch moves the creation of the PID file until after syslogd has
set up signal handlers and is ready.

a4747230ab login: update UTMP before forking
/bin/login updates the preliminary UTMP record created by /bin/getty for
$LOGNAME.  However, if the PID of login is not the same as getty, then
it will create a new entry.  This causes GLIBC getlogin(3) to return the
string 'LOGIN' (set by getty) instead of $LOGNAME.  This affects tools
like /usr/bin/logname but also various 3rd party PAM applications.

89f063b900 chrt: support for musl C library
musl "implements" several sched_xxx() functions by returning ENOSYS. As
an alternative, either pthread_(g|s)etschedparam() or direct syscalls
can be used.

those applets are disabled. Bloat-o-meter when one of those is enabled:
