This patch adds support for handling the error when the command is wrong formed.
Now, if we send a shell/run command and the shell command is incomplete,
the program crashes.
This patch changes the command process blocking the execution until is processing.
Moreover, the response will be OK (200) instead of IN_PROGRESS (202).
Right now, all the thread functions are declared inside the processor function.
Those functions were created for execute specific commands in the machine
(poweroff, reboot, etc). Creating this new class we are cleaning up the code.
Opengnsys needs a support to execute commands on the machine. This patch adds
the support for executing two new commands "shell/run" and "shell/output". The
first one, give us the support for executing a command in the machine and keep
save in a queue the output. The second one, give us the support for sending the
output from the command executed.
