Tell the skytraq to not bother sending a bunch of the NMEA messages
that we don't parse.
Explicitly look for 'G' follows by 'P' instead of having some general
header matching code.

Having an explicit cast in the ao_xmem wrapper macros caused the
compiler to generate garbage values for pdata addresses, making the
upper byte 0x00 instead of the required 0xf0. Removing the
casts from the ao_xmem macros exposed this problem, so a new
PDATA_TO_XDATA macros was added, along with a CODE_TO_XDATA macro
which serve to cast pointers, with suitable address modifications, so
that things work again.

Just mess around with the code to make it smaller. These patches save
173 bytes.

These are significantly smaller than the general pointer versions from
libc on the cc1111.

We can't write general purpose SPI slave code as we must eliminate
any latency because the SPI ports have no buffering.

This code is useful whenever the BT stuff is acting up, so just leave
the source in place, turned off by default.

Split out sources into separate directories:
core: architecture and product independent bits
cc1111: cc1111-specific code
drivers: architecture independent drivers
product: product-specific sources and Makefile fragments
util: scripts for building stuff
This should have no effect on the built products, but testing is encouraged
