Make it modular

[majenkotech]

We need to make pic32prog modular. That is, make it so that different adapters (and their dependant libraries of course) can be turned on and off at compile time.

I have a situation right now where I am trying to compile it under uClibc-0.9.33.2 and it is throwing a complete wobbly (that's a technical programmers' term) with the pthreads. Since all I need from it is the UART adapter(s) it would be nice to "disable" all the USB ones (since it's in the USB HID driver code that the pthreads are used) and just have the adapters that I need in there.

Maybe (yes, I know it's ghastly) an autoconf-automake system would be in order...

./configure --disable-hidboot --disable-an1388 --disable-mpsse --disable-pickit2 --disable-uhb --disable-bitbang

I have made an initial test in a branch of my own fork:

At the moment (until I can work out how to change it) all adapters are disabled by default, so you need to enable the ones you want when you configure. It tells you how.

I have no clue what it does in Darwin...
