bca5c556c4 udhcpc: use readlink rather than realpath
The realpath utility requires all paths exist when canonicalizing
symlinks.  If /etc/resolv.conf points to a tmpfs, then it might
not exist initially.  Use `readlink -f` so that we follow all
symlinks that are available.

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):

9fed24c031 udhcpc: tweak math shell style with the metric var

feature (because it is listed as optional).  Tweak the shell script to

39b8fb41c5 udhcpc: support resolv.conf symlinks
Often it is desirable to have /etc/ be on read-only storage (well, the
whole rootfs) but have things like /etc/resolv.conf be symlinks to a
writable location.  Tweak the simple script to support that.
