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.

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.

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.

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.

147257efa4 Almost functional OTA support
ota_basic example can receive new image via TCP.

However - writing to flash with interrupts disabled causes data loss,
and the TCP flow is very slow to recover. Linux sender quickly ramps up
RTT timer to very long retry intervals, crippling performance &
throughput.

Running the update without the flash writes causes the data to be
received quickly, so this is definitely an issue with the time taken for
the erase cycle.

Progress towards #10

a566a51c09 Use linker scripts rather than libcirom/objcopy tricks to arrange
IRAM/IROM sections.

esp-open-rtos compiled code: .text goes into irom by default, symbols
explicitly marked with IRAM attribute go into iram.

SDK code: .text goes into iram by default, symbols marked with
ICACHE_FLASH_ATTR go into irom.

libgcc functions also go into iram by default.

0dbb6d31a5 Add IRAM attribute for IRAM loaded symbols, add to common FreeRTOS functions
Closes #7.

It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.
