nrf: fix off-by-one in modulo of runtime.ticks
...
This code:
foo & 0xffffff
Is equivalent to this code:
foo % 0x1000000
However, to drop the high 8 bits, this calculation was used:
foo % 0xffffff
This is far more expensive (and incorrect), as it needs an actual modulo
operation which increases code size and probably reduces speed on a
Cortex-M4 and needs library functions for a Cortex-M0 increasing code
size by a much bigger amount.

all: change special type __volatile to pragma //go:volatile
...
This is one step towards removing unnecessary special casts in most
cases. It is also part of removing as much magic as possible from the
compiler (the pragma is explicit, the special name is not).

avr: convert initialization from asm to Go
...
This increases code size by 1 instruction (2 bytes) because LLVM isn't
yet smart enough to recognize that it doesn't need to clear a register
to use 0: it can just use r1 which is always 0 according to the
convention. It makes initialization a lot easier to read, however.

runtime/unix: panic: call abort() instead of exit(2)

abort() will cause gdb to show a backtrace when running inside the
debugger, and abort() seems more appropriate anyway for critical errors.

all: use a custom sync package
...
The sync package is strongly tied to the runtime, so it's easier to
implement a new one. Besides, it's pretty big so it's better to replace
it.

all: rewrite sleep function
...
time.Sleep now compiles on all systems, so lets use that.
Additionally, do a few improvements in time unit handling for the
scheduler. This should lead to somewhat longer sleep durations without
wrapping (on some platforms).
Some examples got smaller, some got bigger. In particular, code using
the scheduler got bigger and the blinky1 example got smaller (especially
on Arduino: 380 -> 314 bytes).

all: remove last traces of the C runtime

This increases code size on the nrf, but it is a fixed increase and can
hopefully be reduced in the future.
The Makefile gets a lot smaller with this which is a huge advantage
(less build time complexity).

This specifically fixes unix alloc(): previously when allocation fails

lacking escape analysis.
Also, all other cases shouldn't try to allocate just because something
bad happens at runtime.
