90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

c312c4b4dc drivers/rng: simplify Kconfig
For all sandbox systems with DM_RNG we enable RNG_SANDBOX. So we can simply
set the default to yes.

All rng drivers depend on DM_RNG. Use a single 'if' instead of individual
dependencies. Now 'make menuconfig' shows the individual drivers neatly
indented under the DM_RNG entry.

1611235b85 lib: Kconfig dependencies for pseudo-random library
drivers/rng/sandbox_rng.c requires rand() to be defined but configuration
option CONFIG_CONFIG_LIB_RAND selected in drivers/rng/Kconfig does not
exist.

test/lib/test_aes.c requires rand() to be defined.

Fix the selection criteria for choice "Pseudo-random library support type".
