support temporary/fixed virtual machines

[RodrigoDornelles]

categorize into two types of virtual machine, fixed and temporary. the purpose is to facilitate the creation and destruction of machines to simulate memory protection feature.

it can also be useful in projects where machines are constantly created and destroyed.

fixed machine

are indicated for when greater control over the machine is needed, such as an orchestrator embedded in another language. (ideal for working with pools)

• it can be restarted, for reuse.
• its ID is unique during the running program.
• the lang_3bc_destroy function just erase data but keep reserved space.
  • use lang_3bc_really_destroy function to actually destroy when needed.

temporary machine

• can't be reused
• your ID is reusable.
  • the ID is not unique over time, but it only exists in one instance at a time.
  • when deleted its ID is in a list for reuse, in which when a new temporary machine is created it can end up using it.
• the functions lang_3bc_destroy and lang_3bc_really_destroy completely destroy the machine.
