Fix crash issue of app-defined-loader

The argument of Plugin::PrepareApp() should not be nullptr.
This patch modifies that the implementation of the Plugin::PrepareApp() allows
the empty string. If the argument is the empty string, the nullptr will be
passed to the plugin function.

Add a new launch mode

The "Always Loader With Low Priority" mode is added to the LaunchMode.
If it's set, an application will be executed using the loader process.
And, the loader process is executed with the low priority.
When getting the launch request, the launchpad-process-pool sets the high
priority to the process using the boosting API.

Support Launch Mode

The platform developer can set the launch mode of the app execution about
the loader using the configuration file.
There are 4 modes as below:
 1. Mode=Previous_Operation:
  - This mode is the original behavior. If the loader is not preapred,
  the application will be executed using fork() & execv().
 2. Mode=Default_Operation:
  - This mode is the default behavior from Tizen 8.0.
  - If the loader is not prepared and the loader is running, the launchpad
  waits until the loader is prepared. And then, the launch request will
  be delivered to the loader process.
 3. Mode=Always_Loader:
  - This mode is that the application will be  always executed using
  the loader process.
  - Even if the loader process is not executed, the launch request will
  be delivered to the loader process.
  - If the loader process is not executed, the launchpad executes
  the loader process when getting the launch request.
  - After processing the launch request, the launchpad executes the loader
  process when the pending request exists.
 4. Mode=Always_Loader_Without_CPUChecker:
  - This mode is the modified version of the "Mode=Always_Loader".
  - The loader process will be executed after processing the launch request.

Remove blocking and unblocking all sub threads

If the launchpad library tries to block the sub thread, the main thread
can be blocked. Because, if the sub thread calls the dlsym(), the global
mutex is locked. In this case, the main thread can be blocked by the mutex.

Modify launch request handling

If the loader context is not prepared, the launchpad does not wait for
the loader is ready. Even if it's not prepared, the launchpad wait until
the loader is ready when the loader is hydra mode.
And, When setting the process ID of the loader context, the launchpad
sends the result to the caller if it is pending.

Fix crash issue of first dotnet application to be executed

There is a problem about loading the launcher info in the AppExecutor class.
In the previous implementation, the AppExecutor created the process pool
before initializing the launcher info. It causes the crash issue.
If the launch request is for dotnet or dotnet-nui app-types, the process pool
cannot execute it properly. Because, there is no launcher info.
This patch modifies the process pool initialization of the AppExecutor.
