Refactor Launchpad Hydra

The launchpad hydra libary is implemented using C++ language.
The process pool is added to the hydra loader. And, this patch decreases
the number of the process pool of executors to one from two.
The liblaunchpad-glib library is added to separate the libary related to
glib from the liblaunchpad-common library.
It's for the liblaunchpad-hydra library.

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.

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-"

exists. To avoid blocking the main thread of the launchpad, this patch

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()
