* Removed some variants of the SYS_GETINFO calls from the kernel; replaced them with new PM and utils libary functionality. Fixed bugs in utils library that used old get_kenv() variant. * Implemented a buffer in the kernel to gather random data. Memory driver periodically checks this for /dev/random. A better random algorithm can now be implemented in the driver. Removed SYS_RANDOM; the SYS_GETINFO call is used instead. * Remove SYS_KMALLOC from the kernel. Memory allocation can now be done at the process manager with new 'other' library functions.
