* libc/Kconfig and stdio/lib_libvsprintf.c: Add an option to disable
support for long long formats in lib_vsprintf. From Alan Carvalho
de Assis (2015-05-30).
* net/net_initialize.c, net/detdev, and net/socket: The network device
list was protected by a re-entrant semaphore. With the recent change
to support network device callback, the network stack needs to access
the network device list too. Some drivers, however, run the network
stack from the interrupt level -- this is bad but a fact in the
current state. Of course, those drivers are unable to take the
semaphore and would assert.
The solution here is to eliminate the device devices semaphore
altogether. This eliminates netdev_semtake() and netdev_semgive()
and replace them with net_lock() and net_unlock() which have the
larger scope that is needed and will integrate properly with the
dinosaur interrupt driven stack (2015-05-31).
