crypto/win: Don't use disallowed APIs on UWP

CreateFiber and ConvertThreadToFiber are not allowed in Windows Store
(Universal Windows Platform) apps since they have been replaced by
their Ex variants which have a new dwFlags parameter.

This flag allows the fiber to do floating-point arithmetic in the
fiber on x86, which would silently cause corruption otherwise since
the floating-point state is not switched by default.

Switch to these "new" APIs which were added in Vista.

Reorganize local header files

Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

'*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

Refactor the async wait fd logic

Implementation experience has shown that the original plan for async wait
fds was too simplistic. Originally the async logic created a pipe internally
and user/engine code could then get access to it via API calls. It is more
flexible if the engine is able to create its own fd and provide it to the
async code.

Another issue is that there can be a lot of churn in the fd value within
the context of (say) a single SSL connection leading to continually adding
and removing fds from (say) epoll. It is better if we can provide some
stability of the fd value across a whole SSL connection. This is
problematic because an engine has no concept of an SSL connection.

This commit refactors things to introduce an ASYNC_WAIT_CTX which acts as a
proxy for an SSL connection down at the engine layer.

Async error handling and MacOS/X fixes

In the async code for MacOS/X define _XOPEN_SOURCE (if not already
defined) as early as possible. We must do this before including
any header files, because on MacOS/X <stlib.h> includes <signal.h>
which includes <ucontext.h>. If we delay defining _XOPEN_SOURCE
and include <ucontext.h> after various system headers are included,
we are very likely to end up with the wrong (truncated) definition
of ucontext_t.

Also, better error handling and some code cleanup in POSIX fibre
construction and destruction. We make sure that async_fibre_makecontext()
always initializes the fibre to a state that can be freed.

For all implementations, check for error returns from
async_fibre_makecontext().

Swap to using proper windows pipes

We were using _pipe to create a pipe on windows. This uses the "int" type
for its file descriptor for compatibility. However most windows functions
expect to use a "HANDLE". Probably we could get away with just casting but
it seems more robust to use the proper type and main stream windows
functions.
