Subject: [ruby-core:48384] [ruby-trunk - Feature #6695] Configuration for Thread/Fiber creation

Same as #6693 ...

= Abstract

With Feature #6694, the following configuration parameters should be allowed for Thread/Fiber creation.

Group1 (new parameters):
* name: Thread/Fiber name
* vm_stack_size: VM's stack size
* machine_stack_size: Machine stack size

Group2 (existing parameters):
* local_storage: Initial Thread/Fiber local parameters
* thread_group: Thread group (Thread only)
* priority: Initial priority Thread#priority= (Thread only)
* abort_on_exception: abort on exception (Thread only)

= Background

With Feature #6694, we have a way to specify configurations for Thread creation.  Fiber.new() don't receive any parameters now.

= Proposal

This is a initial proposal of configuration for Thread/Fiber creation.

Group1 (new parameters):
* name: Thread/Fiber name
* vm_stack_size: VM's stack size
* machine_stack_size: Machine stack size

vm_stack_size and machine_stack_size are OS dependent (This means that it will be *hint* parameter).

Thread#inspect should use `name' parameter.

I also propose a new method Thread#name to get the thread name specified by this parameter.

Group2 (existing parameters):
* local_storage: Initial Thread/Fiber local parameters
* thread_group: Thread group (Thread only)
* priority: Initial priority Thread#priority= (Thread only)
* abort_on_exception: abort on exception (Thread only)

Now, we can specify Group2 parameters only *after* thread creation.  With this parameter, we can specify parameters before thread creation.
