x86: add read-before-write check at runtime

Finding read-before-writes statically is quite difficult. In native we
can use valgrind, but on boards without an MMU we are out of luck.

x86 has an MMU, let's use it.

If `-DDEBUG_READ_BEFORE_WRITE` was set, then pages on the heap get
initialized upon first use. If the page was read before written, then a
debug message with the virtual and physical address of the memory
location is printed, as well as the address of the offending instruction.
you can never have enough debugging in RPL
some minor fixes and debugging
set correct transceiver stack size for debugging
fixed debugging for cc110x
net: IPv6: RPL: more debug output
rpl: debug: use DEBUGF where necessary
core: fix variable name for sched_pidlist
Merge pull request #1272 from OlegHahm/sched_pidlist_fix

core: fix variable name for sched_pidlist
wireshark: fix dissector plugin and expand documentation

The wireshark dissector plugin currently fails with a "Lua Error" when
trying to parse nativenet packets. This patch restores working behaviour
by commenting the offending line introduced in 1258675, which intention
was to account for padding in small packets. It further adds a comment
on how to edit the plugin for the case padding information is required.

The README.md now contains a usage note for configuration on fedora
which might also be helpful for users of other distributions.
tests: add test_vtimer_msg_diff

This test sets three timers and renews them periodically, showing the
difference they accumulate.
tests: test_vtimer_msg_diff: use array for timers, change first to 1s
tests: test_vtimer_msg_diff: add some timers, change max values
destiny: wireshark compliant tcp flags
This enum is also used to set the tcp flags within a tcp header.
With the current values in this enum, wireshark is not able to
recognize the tcp segments as their actual tcp type,
and thus odd messages in wireshark appear.

destiny: reusing tcp flags for combinations
destiny: fixed condition for error handling
send_tcp returns either the length of the sent data,
or -1, if an error was detected.

The current implementation checks for != 1.
This results in executing the error case, although
there was semantically no error returned from send_tcp.
