Add a new option to the loader configuration

The "CONDITION_PATH_EXISTS" option is added to the loader configuration.
The option is for the "ON_BOOT_TIMEOUT" option. If the path does not exist,
the launchpad does not prepare the candidate process. And, the launchpad
adds a timer to wait until the path exists. The interval of the timer is 100 ms.

Delete unused files after process shutdown

After the process is terminated, the launchpad deletes unnecessary files.
To debug & profile dotnet applications, the coreclr creates "clr-debug-pipe-"
and "dotnet-diagnostic-" files. The launchpad deletes the files if the files
exists. To avoid blocking the main thread of the launchpad, this patch
creates a new worker thread that is "RecycleBin+".

Modify loader priority feature

After this patch is applied, the loader priority feature is basically activated.
The platform developer can adjust a scheduling priority using
the loader configuration file.
The 'SCEHD_PRIORITY' tag is added for the loader process.
The loader developer can set the scheduling priority as below:
+------------------------------------------------------------------------------+
| [LOADER]                                                                     |
| NAME hw-loader                                                               |
| ...                                                                          |
| SCEHD_PRIORITY         -20                                                   |
+------------------------------------------------------------------------------+

The range of the priority is -20 to 19. (-20 being the highest priority
and 19 being the lowest priority.)
If the loader has the sched priority tag, the child process sets
the scheduling priority using the configure information after the process
is created. And then, the loader process sets the priority to the normal
priority before running the main loop.

Add new APIs for loader process

Before calling the loader_launch_cb() callback function, the loader process
has to make blocking all sub threads if a new thread is able to be created by
the sub thread. This patch adds new functions for the loader process.
Some loader process creates a new process while calling the security_manager_prepare_app2().
It makes an application launch failure issue.

When calling the loader_prelaunch_cb() callback function, the loader should call
the launchpad_loader_block_threads() to make blocking all sub threads.
And then, the loader calls the launchpad_loader_unblock_threads() while calling
the launchpad_launch_cb() callback function.

Even if the sub thread creates a new thread while calling the launchpad_loader_block_threads(),
it handles by the security_manager_prepare_app2() function.
This is not complete solution. But, this patch is able to reduce the risk about
the launch failure issues.

Adds:
 - launchpad_loader_block_threads()
 - launchpad_loader_unblock_threads()
