d553be5982 build: Simplify build directory layout by putting all headers in genhdr. 
Any generated headers go in $(BUILD)/genhdr/, and are #included as
'genhdr/xxx.h'.

efc22e376f stmhal: Fix 64-byte USB packet bug properly. 
A 64-byte packet is now followed by a 0-byte packet if there is nothing
more to send.  This flushes the USB endpoint.

6d983539bc stmhal: Improve flash storage cache management. 
Internal flash used for the filesystem is now written (from the cache)
only after a 5s delay, or when a file is closed, or when the drive is
unmounted from the host.  This delay means that multiple writes can
accumulate in the cache, and leads to less writes to the flash, making
it last longer.

It's implemented by a high-priority interrupt that takes care of flash
erase and write, and flushing the cache.

This is still only an interim solution for the flash filesystem.  It
eventually needs to be replaced with something that uses less RAM for
the cache, something that can use more of the flash, and something that
does proper wear levelling.

70a7d7a943 build directory can now be renamed 
The autogenerated header files have been moved about, and an extra
include dir has been added, which means you can give a custom
BUILD=newbuilddir option to make, and everything "just works"

Also tidied up the way the different Makefiles build their include-
directory flags

9388a90842 stmhal: Fix USB CDC buffer overrun error. 
Need to wait for the low-level USB driver to send the data over the USB
in-endpoint before the buffer can be used again.  This patch adds a
check for this.

9699ea6a2f stmhal: Fix USB MSC so that it unmounts correctly on Mac OS X. 
Mac OS X sends a SCSI command to remove the medium when it unmounts a
drive.  If this command is not honoured, then OS X will automatically
remount the drive, making it impossible to eject.  This patch disables
the USB MSC when the right SCSI command is sent.

4d7f4eb6a9 stmhal: Add ADC function to read data at a given frequency. 
Reads ADC values into a bytearray (or similar) at a fixed rate.  Needs a
better name and improved API.  Also fix up DAC dma function (which also
needs a better name and API).

Tweak pybcdc.inf to match recent changes to pybcdc.h

3f4898456b stmhal: Add stm module, which contains some constants for the MCU. 
Also contains raw memory read/write functions, read8, read16, read32,
write8, write16, write32.  Can now do:

stm.write16(stm.GPIOA + stm.GPIO_BSRRL, 1 << 13)

This turns on the red LED.

With the new constant folding, the above constants for the GPIO address
are actually compiled to constants (and the addition done) at compile
time.  For viper code and inline assembler, this optimisation will make
a big difference.  In the inline assembler, using these constants would
not be possible without this constant folding.
