b6c2e4df59 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.

b03f279f74 mbedTLS: Add ESP8266 hardware entropy source discovered by @foogod

1b22cc088e Add initial mbedTLS and HTTPS example project (using howsmyssl.com JSON API)
mbedTLS version 2.1.0 (current stable)

Has some known issues/hacks:
* Entropy source not hooked in at all
* Linker script has a messy hack in it to store some (not all) data in

f230fbcd65 Move start of IROM0 to 0x40220000, save 128kB of flash
Old starting point left 256kB for RAM sections, but I think they
shouldn't ever possibly exceed 128kB.

1c9e106db8 Compile with -ffunction-sectons -fdata-sections, link with -gc-sections
This seems to shrink code size by abou 3.5%. Not sure if there are any downsides.

3aff91c85c 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

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.
