kernel_ldr: use unoptimized memcpy before mmu bringup (closes #1102) ...

Before the MMU is up, all reads/writes must be aligned; the optimized
memcpy implementation does not guarantee all reads/writes it performs
are aligned.

This commit splits the libc impl to be separate for kernel/kernel_ldr,
and so now only kernel will use the optimized impl. This is safe,
as the MMU is brought up before kernel begins executing.

kern: switch memset to optimized impl

kern: use optimized memcmp/memcpy implementations

kern: fix link error

kern: Implement SvcManageNamedPort

memset: use neon-less impl, reformat other asm

libmesosphere: use ARM-software/optimized-routines for memcpy/memset/memcmp

kern: use TinyMT instead of mt19937_t

kern: implement enough of KPageTable to initialize a thread

meso: use -fno-non-call-exceptions, -fno-use-cxa-atexit

kern: mostly implement KThread::Initialize
