Improve fiber backtraces

Update based on php-src implementation

Revert context return

On second thought, this wasn’t actually useful.

Remove fcontext_t and transfer_t from fiber.h

We don’t really want to define these outside of fiber_asm.c.

Use preallocated context

Removed just-added data pointer as this approach makes it unnecessary.

Provide fiber context to and from internal API functions

Few other minor nits

A few minor fixes and nits

Switch to {main} for fatal errors

Minor stylistic changes

Combine create and initialize context functions

Remove stack_size property

Accessable through fiber->context->stack.size.

Remove initialized flag

Remove root context

Remove initial jump/suspend

Update file header

Thanks to Martin Schröder for the original code and inspiration, but I should be the main contact for questions and maintance of this code. Very little of the original cod

Remove indirection for fiber context

Since asm is always used, zend_fiber_context can be defined as a struct instead of a void*.
