Kees Cook 81b785f3e4 x86/boot: Rename overlapping memcpy() to memmove() ...

Instead of having non-standard memcpy() behavior, explicitly call the new
function memmove(), make it available to the decompressors, and switch
the two overlap cases (screen scrolling and ELF parsing) to use memmove().
Additionally documents the purpose of compressed/string.c.
