After removal of the network drivers as an entropy source in Linux kernels a
while ago, some routers e.g. in ar71xx family experience lack of hardware
entropy for /dev/random. The device /dev/random can hang due to that. There
are pseudo random numbers available in /dev/urandom, but they do not end up
in /dev/random.
E.g. tickets #9631 and #9999 are related to this problematics.
One tool for adding entropy data from an arbitrary source to the kernel
entropy pool is rngd daemon included in the rng-tools package from
http://sourceforge.net/projects/gkernel/
Manual page: http://linux.die.net/man/8/rngd
The tool can be used to add entropy to the kernel's entropy pool either from
some genuine hardware-based entropy source, or as a quick&dirty patch also
from /dev/urandom. Using urandom isn't a perfect solution, but it will
satisfy those applications looking for input from /dev/random.
As far as I found out, nobody has complied the rngd daemon package for
Openwrt, so far.
I made a try out of it, and succeeded both for Backfire and trunk.
I defined a package that downloads the sources from SF. (This is my first
package definition, so the dependencies and conventions might not be quite
correct, but the package seems to compile and work both in Backfire and trunk.)
Hopefully somebody can figure out a way to connect some real entropy source
in ar71xxx devices through this daemon. The package could be used with real
hardware entropy sources (like the Entropy key), if they provide a suitable
interface for the daemon to the entropy data from them.

Build libbz2 and make bzip2 depend on it. libbz2 is necessary for
packaging bsdiff.

The compile-time generation of the valgrind linker script broke due to toolchain updates
resulting in valgrind binaries compiled with the standard load address of 0x08048000 which
leads to memory conflicts with the debug client later on; valgrind will abort with the
message below:
valgrind: mmap(0x8048000, 348160) failed in UME with error 22 (Invalid argument).
valgrind: this can be caused by executables with very large text, data or bss segments.
This change adds another sed pattern to properly substitute the current linker script format.

The update is required as the old filename
usb-modeswitch-data-20110705.tar.bz2 is no longer hosted on
http://www.draisberghof.de/usb_modeswitch/
BTW, the two openwrt.org backup servers do not hold either the old
usb-modeswitch-data-20110705.tar.bz2 nor the new
usb-modeswitch-data-20110805.tar.bz2
In effect there is a dependency on one external server. If they decide
to change to a new version and not continue hosting the old, the
compilation breaks. The sources on the openwrt,org servers should
therefore be urgently updated.

This bumps dbus in the packages repository to 1.4.14.
It also requires librt now due to clock function usage.
It also supports systemd and launchd now.

mc will link against ncursesw instead of ncurses if it finds it. Make sure
it always links only against ncurses.
Closes#9225 and #9315.
