* cpuid.h: Add missing copyright header. Fix formatting. Use uint32_t

instead of unsigned throughout.  Change functions to static inline and
	always inline.
	(cpuid): Add parameter to set ecx, allowing to request extended CPUID
	info.
	* fhandler_proc.cc (format_proc_cpuinfo): Use uint32_t instead of
	unsigned throughout.  Add fake decimal places to MHz info.  Handle more
	feature flags.
	* fhandler_random.cc (fhandler_dev_random::write): Allow up to 4K
	input to add entropy.
	* syscalls.cc: Drop including cpuid.h.
