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.

18381f88fe mbedTLS: Add ESP8266 hardware entropy source discovered by @foogod 
Addresses #3, provided turns out to be an effective HWRNG.

77813c8032 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

aea147ad6a 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.

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')
