Rename Stack::top() to Stack::base(), which is correct.
...
Fixes #25 .

Add more examples to README.
...
This also renames some functions for a mild increase in backtrace
clarity.

Don't use core::intrinsics.
...
The core::intrinsics::unreachable() we used at the end of every naked
function is essentially pointless, as #[naked] implies that intrinsic
at the end of the function. rustc currently does not implement that
behavior (rust-lang/rust#32487 ), but it is a bug. On top of that,
anything except a single asm!() in naked functions is likely to be
disallowed in the future (rust-lang/rust#32490 ).
A nice side effect is that we avoid the core_intrinsics feature,
which will be never stabilized, though neither asm nor
naked_functions are likely to be stabilized soon.

Clarify the Windows situation.
...
Also, remove the Windows OsStack implementation. It will not ever
be useful in libfringe, as even if we add support for Windows
using fibers, the OS allocates stacks for fibers and we needn't
do it manually.

This concludes preparations for making Context private again.

Allow unwinding to propagate across a context swap.
...
The main purpose of this is having nice backtraces in gdb, although
it also slightly simplifies poisoning state of the API consumers
after a panic.

Kill impl StackPointer.
...
That was a silly idea for a silly abstraction, and it brought no
improvement, only confusion. So, revert it.

Completely rework fringe::Context and fringe::arch.
...
The new design concerns itself with one thing and exactly one thing:
passing values back and forth with an extern "C" function.
This allows to simplify fringe::arch into a single primitive, swap.
