Add dependency to capi-base-common

It is required for the header tizen.h and enums such as TIZEN_ERROR_*
defined at the header. Those are accessible by the dependency to the
capi-base-common, which is currently pulled in by the dlog. However,
some build environment lack of such indirect dependency would blame
this. Therefore explicitly state the dependency.

halcc: Remove checking SYSTEMD_SCOPE environment variable

The environment variable is used for testing whether the execution
context is systemd system generator. And for this, getenv() had been
utilized. However, there was a blame that the getenv() is vulnerable
as the environment variable could be controlled externally. Therefore,
removed using SYSTEMD_SCOPE environment variable.

Due to this, it has become that someone can create compatibility result
file, /opt/etc/hal/.hal-backend-compatibility, outside of systemd system
generator context. Nevertheless, we can screen out the worst case that
unprivileged process generates the file because the directory /opt/etc
has attribute of {root,system_share,0775}.

 As compatibility manifest has changed to specify multiple version for
hal, the halcc compatibility checker has also been fixed to follow
that scheme.

 1. The result file format has changed so that the halcc can now randomly
    access to module index for which the halcc has requested.

 2. Operation for generating result file will be rejected unless it is
    invoked by generator of systemd system manager. Therefore, if there
    is no result file when checking compatibility, and it is not on
    generator context, compatibility checking will do the entire
    routine, for every invocation, that should have done when creating
    the result file.

 3. For updating manifest file from a hal api repository, add below
    command at %post rpm scriptlet.
      : rm -rf /opt/etc/hal/.hal-backend-compatibility
      : systemctl daemon-reload
    systemctl daemon-reload triggers generator so it is able to create
    a new result file from updated manifest.

halcc_hal has changed to manage multiple version within a list, it
cannot test a specific version is in the list but can test whether

  halcc_manifest_find_hal(manifest, hal_name, major, minor, hal)
    -> halcc_manifest_find_hal(manifest, hal_name, hal)

halcc_manifest_find_hal() as the default behavior of finding hal is
not based on version, but only on name.

halapi: Add hal-api-manifest.xml

The hal-api specifies which version it requires to a hal backend
module. The manifest file must be installed in the following directory:
 - /etc/hal-manifest/hal-api-manifest.xml

Manifest scheme:
 <manifest version="1.0" type="platform">
     <hal>
         <name>HAL_MODULE_XXX</name>
         <version>1.2</version>
         <version>2.0</version>
         <transport>passthrough</transport>
     </hal>
 </manifest>

 The above specifies that a platform has hal api version of both 1.0-2
and 2.0. The name, in this case the HAL_MODULE_XXX, must be one of an
enum hal_module. (See include/hal-common.h) It expects for hal backend
to have version that specified in <version>. Here the 'compatible' means
that backend version should have major version equal to platform, and
minor equal to or lesser than platform. At the above case, here is
compatible set of backend version:
 - Compatible backend version: 1.0, 1.1, 1.2, 2.0
 - Incompatible backend version: 1.3, 2.1, 3.0, ...

 As aforementioned, a platform must contain all set of apis as it has
specified on manifest <version>. For example, a hal api that specified
the above manifest must have all apis like below.
  // hal-xxx.h
  int hal_xxx_foo(); // Implemented as of v1.0
  int hal_xxx_bar(); // Implemented as of v1.1
  int hal_xxx_baz(); // Implemented as of v1.2
  int hal_xxx_qux(); // Implemented as of v2.0

 Note that, for backward compatibility, all functions with older minor
version as well as the latest minor version must be provided together.
And they cannot be removed as the minor bumps within the same major
version.
 It works based on which backend version would have been. If a platform
works on top of backend version of 1.1, the foo and bar will works
whereas baz and qux won't, returning not supported error, for example.
Note that even though the platform has implemented baz since v1.2, it
won't work as backend has no idea about v1.2.
 For backend version of 1.3, for example, all the foo, bar, and baz
won't work. (qux obviously won't too due to major version mismatch)
The backend v1.3 might have implemented all v1.0 ~ v1.3 functionalities
for backward compatibility though, it is possible that v1.2 platform
could not understand semantic of v1.3 that will have been given in
the future. To prevent this, platform refuses to work with backend
of future minor version.

 If a new hal api is added with major or minor version bump, fix the
manifest file through ACR process.

halapi: Add function checking all of the HAL compatibility

Previously, the API provides callbacks that give responsibility to
the caller that storing compatibility result in their own way. However,
to provide a unified way of storing and loading HAL compatibility,
hal-api-common has become responsible for storing and loading
compatibility in a unified manner.

int hal_common_check_backend_compatibility_all()
  : It gets compatibility of all the hal modules. Additionally, it
    stores compatibility of all modules to backing storage if there
    hasn't been for later use.

Currently, the result is stored in /opt/etc/hal/.hal-compatibility and
the below is an example of result generated by hal-compatibility-checker:
  root:/opt/etc/hal> cat .hal-compatibility
  0:Not defined:0:Manifest hasn't specified the module

halcc: Introduce halcc library

The halcc stands for hal compatibility checker.

Tizen hal-apis can specify what feature and version it expects to
hal-backends in manifest file. The halcc library deserializes and
utilizes the information for checking compatibility between
hal-api and hal-backend.

For example, a hal-api specifies what it needs in xml file:

  | <!--hal-api-xxx.xml-->
  |
  | <manifest version="1.0" type="platform" level="2">
  |     <hal>
  |         <name>AAA</name>
  |         <version>3.1</version>
  |         <transport>passthrough</transport>
  |     </hal>
  |     ...
  | </manifest>

It means that the hal-api expects and requires hal-backend module name
of AAA, and version of 3.x where x >= 1.
(See semantic versioning, https://semver.org)

These are collected and tested by the halcc library.

Currently only the function below is provieded
 - int halcc_check_compatibility(const char *hal_api_manifest_dir,
     halcc_compatibility_cb callback, void *user_data)
   : It collects manifest files at hal_api_manifest_dir and checks
     whether the hal-backends have compatible what hal-apis have
     specified. For each specified <hal> in manifests, callback is
     invoked.

tests: unittest: Add new test for hal_common_get_backend_with_library_name

Basically, the hal backend library name of each module is already decied
such as 'libhal-backend-[module name].so'. But, some module requires
the hal backend library loading way with their own library name
like 'libhal-backend-[module name]-lidar.so'.

When loading the their own library name, hal_common_get_backend_with_library_name
and hal_common_put_backend_with_library_name are used.

So that add new for hal_common_get/put_backend_with_library_name
and add 'backend_module_name' attribute to class HalInfo
because 'backend_module_name' is required to check the hal backend name
as I mentioned above.

tests: unittest: Add hook function for handle hal backend library

The hal-api-common uses the dlopen/dlsym/dlclose to load/unload
the shared library of hal backend and find symbol from hal backend library.
For testing hal-api-common functions when building time, re-implement
dlopen/dlsym/dlclose for hooking.By implementing the hooking functions,
be able to verify the internal logic of hal-api-common functions.

Following fucntions are re-implemented for hooking:
- void *dlopen(const char *filename, int flags)
- int dlclose(void *handle)
- void *dlsym(void *handle, const char *symbol)
- int access(const char *pathname, int mode)

And hal-backend-[module] (e.g., tbm/tdm/audio/camera/devcie/power etc)
have to contain the their own hal_backend structure to implement
the h/w device-dependent hal backend. Instead of adding the each hal_backend
structure for all hal modules, use the common 'hal_backend_module_data'
regardless of hal module name.
