Allocate guard page under existing stack, not in it.
...
This fixes a segfault when the allocated stack is just one page long.
This also refactors the fringe::os module to use Result consistently.

Use mostly the same registers for consistency
...
The exception to this is %eax is used not %edi on x86 because its
caller-save

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.

at least allow different lifetimes in Context::swap2
...
Really we should allow swapping between different stack types easily, so
we can easily swap between contexts with different stack types.

add Context::swap2, to allow distinct save/restore contexts
...
Fix #5
Context::swap is now implemented in terms of Context::swap2, and it
might make sense to remove Context::swap entirely at some point.

remove obsolete support for Rust stack limits
...
rustc removed these in 7a3fdfbf674a08b7f6fd32c9124e52924a2f9a1c, and
this removes a Linux-specific TLS slot from our code.

It's fairly pointless to have submodules when there are only three
items.
