5bce135e36 mdev: improve $SEQ handling; improve debug logging
Sequential run of concurrent mdev's was too simplistic:
they waited for /dev/mdev.seq to match. This could sometimes
cause cumulative loss of time on the order of a second.

Added SIGCHLD signaling from exiting mdev to all other mdev's.
Added debugging required to see that code actually works as intended.

Example of /dev/mdev.log (with "woken up" elevated from dbg lvl 3 to 2):

mdev[1023]: first seq written
     ^^^^ seq, not pid

the partition table appears corrupted because current_label_type will

3917fa32dc dmesg: handle multi-char log levels
Since Linux 3.5 (7ff9554bb5: printk: convert byte-buffer to variable-length
record buffer), klog buffer can now contain log lines with multi-char
loglevel indicators (<[0-9]+>) - So we can no longer just skip 3 bytes.

Instead skip past the terminating '>' like util-linux does.

12677acf0a CONFIG_PID_FILE_PATH: new configuration option for pidfile paths
We set a default path for the directory where pidfiles are create
when FEATURE_PIDFILE is selected.  The default has no effect on
applets which must specify a pidfile path on the command line to
run, and it can be overridden by applets which optionally allow
the user to specify the pidfile path.

We also add pidfile write/remove support for klogd, ntpd and watchdog.
For syslogd, we add a missing remove_pidfile() for better cleanup
on daemon exit.

b5c7220e7b fbset: respect rgba configuration lines in fb.modes
The fbset utility would not respect "rgba" config entries in
the fb.modes file such as this (for the ARM Integrator/CP):

mode "640x480-60-clcd"
    # D: 25.175 MHz, H: 31.469 kHz, V: 59.94 Hz
    geometry 640 480 640 480 16
    timings 39722 48 16 33 10 96 2
    rgba 5/10,5/5,5/0,1/15
endmode

This is important especially for this ARGB5551 device which
is hopeless to configure otherwise. I noticed this lacking
feature after the TI "fbtest" program managed to set up the
the colormode correctly.
