Merge #299
299: Expose __syscall and add new bootstrap method r=jonas-schievink a=adamgreig
We added `__syscall` in the new inline asm, but did not expose it in the crate API, and the cortex-m-semihosting crate can't use it directly because the pre-built binaries would contain duplicate symbols (#271). This PR renames it to `__sh_syscall` (since we could imagine other different syscalls; this one is explicitly semihosting with the `bkpt 0xAB`) and exposes it in `cortex_m::asm::sh_syscall`.
This PR also adds the new methods discussed in #297 to permit sound bootstrapping, either from an MSP and RV or a vector table address.
