4ea9382ee6 Fix bad memory access in NMI handler 
CallNMIExceptionHandler was saving/restoring registers to the wrong offsets,
causing it to potentially corrupt the first two slots of the
LoadStoreErrorHandler's save area.

3ceb07b9db unaligned_load: Run some tests after scheduler/network/wifi all up and running

9d62d09d3f unaligned_load.c: Added more naive_strcpy tests 
Added tests for naive_strcpy using a variety of different regs, as execution time can depend on which register is being used.

3eb43c6ef5 Moved DoubleLoadStorageHandler to end of functions, improve fast path l8ui performance 
This allows a conditional branch that previously required a full jump instruction not to require it.

e4c76b488c Remove the unaligned load handler to its own source file as it was getting quite complex 
The downside here is needing to use #include so the 'beq' in the
exception vector can land on it directly, save an instruction.

There might be a better way to do this, but it seems hard to "curate"
the order that symbols appear in each section.

1221e2117b Rework component makefiles to have a default <component>_ROOT 
This fixes a long-standing bug where build directories sometimes
expanded many levels deeper than they should have.

Component names can now no longer contains slashes (ie the component
name for 'extras/i2c' is now just 'i2c')

c19bb63286 Reorder library arguments so component libraries come first 
This allows components to override weak linked symbols in the core or
the SDK libraries, without needing to force symbol discovery.

Will help with #24, for instance.
