Benjamin Walsh 3181df6db4 kernel: add per-thread errno support
Saves an errno per-thread, retrieved via _get_errno(), instead of
changing the value of a global variable during context switches to avoid
a hit to the context switch performance.

Per-arch asm implementations are provided for maximum performance.

Enabled by default, but can be disabled via the CONFIG_ERRNO option.
