kexec: export kexec.h to user space

Add userspace definitions, guard all relevant kernel structures.  While at
it document stuff and remove now useless userspace hint.

It is easy to add the relevant system call to respective libc's, but it
seems pointless to have to duplicate the data structures.

This is based on the kexec-tools headers, with the exception of just using
int on return (succes or failure) and using size_t instead of 'unsigned
long int' for the number of segments argument of kexec_load().
