cc97067fa1 Add C++ support to Makefile, and proof-of-concept simple.cpp example 
This is a work in progress based on @mikejac's work.

Missing:
* No 'new' operator.
* I don't think STL is currently supported.

a3d7732da8 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.

f47aa77982 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.

c7a7dfdf82 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.

c45e84d61d Rename GPIO_CONF_PUSH_PULL to GPIO_CONF_OPEN_DRAIN 
Seems I got the functionality of this bit inverted when
initially testing.

In testing it also seems open drain mode is ignored on some pins, which
still source current. Needs more investigation though (may be pullups
internal to the ESP modules or set by default in software.)

Relates to #45

7e73693898 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')

0090153fa7 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.

8b8f7c9de4 Use fixed symbol rename list 
To keep things from changing out from under us as we slowly replace bits of the
SDK libs, changing Makefiles to not auto-generate the list of symbols to
rename, but always use the same list every time.
