09fc3a65d9 Fix a memory leak in hotplug2 environment handling. 
Bump hotplug2 to the latest svn revision, remove obsolete patches.

Memory leak is caused by the way hotplug2 handles environment variables,
using setenv() and unsetenv(). setenv() creates copies of the supplied
strings, but, due to a POSIX blunder, these copies are never destroyed
by unsetenv(), neither in glibc nor uclibc - not until the program
terminates.

Since some events are handled directly in the main process, even when
configured with the "fork" worker, hotplug2 memory usage will keep
growing over time. This can be observed by running "udevtrigger" and
noting the increase in hotplug2 VmRSS after each run.

This patch uses putenv() instead, which leaves storage management to
the caller, so that we can explicitly delete stuff when it's no longer
needed.

8878fc63f1 Use block events for the mounting/unmounting of external storage devices. 
This handles both USB and IEEE1394 devices. It removes /sbin/usb-storage in
favor of using the block hotplug event. There are dummy scripts to handle the
plug in/out of USB and IEEE1394 devices for updating LEDs. Storage devices 
are mount as a sub-directory under /mnt.
