Use YamlParser to parse android HAL config files, instead of handling
YAML tokens directly, as a preparation for the further parameter extension.

The Extensible constructor takes a pointer to a Private instance, whose
lifetime it then manages. Make this explicit in the API by passing the
pointer as a std::unique_ptr<Private>.

Error out on any camera's location if set to "external", in the HAL
configuration file. The HAL configuration file is meant to override the
location property, and overriding an internal camera location to
external doesn't make sense.

The Extensible and Extensible::Private classes contain pointers to each
other. These pointers are initialized in the respective class's
constructor, by passing a pointer to the other class to each
constructor. This particular construct reduces the flexibility of the
Extensible pattern, as the Private class instance has to be allocated
and constructed in the members initializer list of the Extensible
class's constructor. It is thus impossible to perform any operation on
the Private class between its construction and the construction of the
Extensible class, or to subclass the Private class without subclassing
the Extensible class.
To make the design pattern more flexible, don't pass the pointer to the
Extensible class to the Private class's constructor, but initialize the
pointer manually in the Extensible class's constructor. This requires a
const_cast as the o_ member of the Private class is const.

Now that all Extensible classes expose a _d() function that performs
appropriate casts, the LIBCAMERA_D_PTR brings no real additional value.
Replace it with direct calls to the _d() function.

Move the functionality for the following components to the new
base support library:
- BoundMethod
- EventDispatcher
- EventDispatcherPoll
- Log
- Message
- Object
- Signal
- Semaphore
- Thread
- Timer
While it would be preferable to see these split to move one component
per commit, these components are all interdependent upon each other,
which leaves us with one big change performing the move for all of them.

On gcc versions older than 9, the file system library, used by the
Android camera HAL configuration file parser, is implemented in a
separate static library. Furthermore, on gcc 7, it's provided in the
std::experimental namespace. This breaks compilation of the HAL on gcc
7, and linking on gcc 8.
Fix the compilation issue by conditionally including
<experimental/filesystem> and creating a namespace alias in std, and the
link issue by linking to libstdc++fs on gcc versions older than 9.
The inclusion of <experimental/filesystem> is a bit of a hack, and when
we'll start using the file system library in another compilation unit,
we should then move all this to an internal helper to abstract the
compiler version.
