Refactor third-party libraries to build from source on Linux (#5706)
Add a way to compile third-party libraries from source instead of downloading prebuilt ones.
Each library source code is downloaded with git into a submodule at configure time,
in response to the find_package(library_name) CMake call,
except for OpenSSL where the official source archive is used.
Each submodule is attached to a release tag on its own upstream repository.
All the libraries are built using CMake directly, except for OpenSSL which uses a formula system,
which permits to build libraries with a separate build system
when there's no easy way to integrate it directly with CMake.

This new dependency system determines which library is fetched from where using the concept of "layers".
Currently we have three of them: source, formula, facebook,
where the last layer represents the pre-built libraries.
The provided order will be used when looking for libraries.

A system to patch submodule source code has been added and it's currently used with googletest, libudev and util-linux.
Patches should be put under libraries/cmake/source/<library name>/patches/<submodule>,
where <submodule> is often one and is "src", but in other cases, like AWS,
there are multiple with a more specific name.
If for whatever reason the submodule cloning or the patching fails,
the submodule has to be unregistered and its folder should be cleared.
This should be achievable with "git submodule deinit -f <submodule path>"

Following some other changes on existing functionality:

- Changed the CMake variable BUILD_TESTING to OSQUERY_BUILD_TESTS
  to avoid enabling tests on third party libraries.
  Due to an issue with glog the BUILD_TESTING variable
  will be always forced to OFF.
- Moved compiler and linker flags to their own file cmake/flags.cmake
- Moved all the third-party CMakeLists.txt used for pre-built libraries under libraries/cmake/facebook
- Added the --exclude-folders option to tools/format-check.py and tools/git-clang-format.py,
  so that it's possible to ignore any third party library source code.
- The format and format_check target use the new --exclude-folders option
  to exclude libraries/cmake/source from formatting.
- The test and osquery binaries are properly compiled with PIE (osquery/osquery#5611)

942878854b Add CMake support
Taken from osql-experimental.

- Change CMake code license to the one present in osquery right now

- Package metadata doesn't mention Trail of Bits or osql anymore

- Set specific ACLs for the osqueryd on Windows when packaging

- Remove LLVM_INSTALL_PATH support on macOS, since we are using AppleClang

- Remove OSQUERY_SOURCE_DIR variable need and source in a submodule support

- Add targets format_check and format to check code formatting and
  format it with clang-format

- Do not warn about not using Clang on macOS when using AppleClang

c7355b19aa Update osquery licensing wording (#5452)
Summary:
Pull Request resolved: https://github.com/facebook/osquery/pull/5452

As suggested in another diff, this diff updates the language we use to describe the osquery licensing terms. We are changing all instances of

//This source code is licensed as defined on the LICENSE file found in the root directory of this source tree.//

to

//This source code is licensed in accordance with the terms specified in the LICENSE file found in the root directory of this source tree.//

We accomplish this with a codemod:

  $ codemod -md xplat/osquery/oss --extensions cpp,h,in,py,sh,mm,ps1 "(.\s+)This source code is licensed as defined on the LICENSE file found in the(.*)root directory of this source tree\." "\1This source code is licensed in accordance with the terms specified in\2the LICENSE file found in the root directory of this source tree."

2d5572d51e Move plugins to a separate directory [2/?]
Summary:
Initial steps to separate plugins from the rest of osquery. On the long run separating plugins will provide more build flexibility such that we can have configurable builds that include only the bits and pieces we actually need per deployment. Reducing the attack surface, possibility of supply chain attacks, binary size, etc.

Move distributed
