Tockloader currently has 2 separate paths for flashing: one for when all apps are PIC and can go anywhere in the flash, and one for when all have fixed positions in the flash (possibly multiple fixed positions).

This separation fundamentally doesn't have to exist, because (presumably) Tock kernel can make sense out of applications and where to put them if it gets a mix of both.

With libtock-c producing PIC binaries, and libtock-rs producing only fixed ones, until this issue is solved, programs using them cannot coexist.

I'm creating this issue as a place to discuss solving this.
