Lock and unlock mutex for process creation

To prevent memory corruption issue, this patch adds locking and
unlocking a mutex. If the memory allocation occurs when creating a
children process using fork(), the children process has a memory problem.

Do not close all file descriptors

When the loader fails to find the main function, it tries to execute
an application using execv(). Before calling execv(), the loader closes
all opened file descriptors. Unfortunately, the loader can have crashed
by that. To avoid crash issues, this patch removes calling CloseAllFds().

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.
