On MacOS, if libgit2 is not found, the build configuration tries to download a static build of libgit2 version 1.8.1 (https://github.com/autobrew/bundler/releases/tag/libgit2-1.8.1) and use that instead, after the sha256 of the downloaded 'libgit2-1.8.1-universal.tar.xz' file has been checked.

Fixed memory protection errors in the git2r C source code reported by the 'rchk' tool.
Raise an error if the path argument to the 'hashfile' function is NA.
On macOS, git2r no longer enables SSH transport by default. This is due to the complexity to build the dependencies for SSH transport in an R package when macOS no longer ships the OpenSSL headers. However, you can install git2r from source on macOS (see the 'R Installation and Administration' manual) with SSH transport enabled if you first install the libgit2 library, for example, using the Homebrew package manager. Another possibility is to let the build configuration automatically download the libgit2 library from the Homebrew package manager with:
install.packages('git2r', type='source', configure.vars='autobrew=yes')
Added the 'git_config_files' method to locate configuration files.

Changed from S4 classes to S3 classes to simplify the design and facilitate future development.
Removed the trailing slash from the directory name when reporting repository path or workdir.

Update build configuration to support OpenSSL 1.1.0.
If the the 'getPass' package is installed the 'cred_ssh_key' method to create a new passphrase-protected ssh key credential object will call the 'getPass::getPass()' method if the private key is passphrase protected to allow for interactive input of the passphrase. The 'getPass' package is a suggested package. (Peter Meissner in PR #254)
Add 'path' argument to the 'reset' method to enable path-specific unstage, i.e. resets the index entries for all paths to their state at HEAD
Build configuration: 'pkg-config' is now used to find 'libssl', if possible (Elias Pipping in PR #231).
