Moved away from ctrtool's polarssl api completely. Brought certs.c/h
inline with code style, fixed bugs relating to tmd savedata field
generation and not recording savedata size from rsf (ncsd.c)
lots cleaned, added cia to cci conv, it
's called a block, separated reading from building, improved ncch keyx
stuff, and basic verbose for keys, elf checking and romfs
added function to fill memory with random bytes (cleaning some code with
that). Removed public build #ifdefs since 3dsguy apparently uploaded the
entire source with all "private" things.
