license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

random: add xoshiro128++ PRNG source Adds an implementation of xoshiro128++ as a pseudo random number generator from https://prng.di.unimi.it/ that operates on 32bit words. The algorithm postfix signifies the main operation in the generation function. Therefore xoshiro++ is chosen over xoshiro** as we would prefer to do 2 additions isntead of 2 multiplications on embedded hardware. The quality of the generators appears to be the same in all other respects. xoshiro+ is not chosen despite being faster as it generates random floating-point values, not general purpose random values (The lower 4 bits are linear).

random: Add syscalls for random subsystem Create syscalls to make possible using random APIs from user mode threads. These APIs can have different implementations, like using entropy driver or Xoroshiro128. Some of these implementations also have some globals to preserve state between calls. Make it run entire in user space would require user adding these globals to their memeory domains and/or grant access to entropy device. Syscalls simplify its usage.

random: Fix non-random number generator warning condition The `TEST_RANDOM_GENERATOR` symbol in itself does not imply that a non-random number generator is selected -- that is indicated by the `RNG_GENERATOR_CHOICE` choices, of which only `TIMER_RANDOM_GENERATOR` is a non-random generator.
