This change introduces the file deprecated.go, which contains any
constants, functions, and types that are slated to be deprecated in the
next major release.
These symbols are deprecated because they refer to old spellings in
pre-1.0 libgit2. This also makes the build be done with the
`-DDEPRECATE_HARD` flag to avoid regressions.
This, together with
[gorelease](https://godoc.org/golang.org/x/exp/cmd/gorelease)[1] should
make releases safer going forward.

#### Problem:
The current `CMAKE_INSTALL_PREFIX` value for the `system` build mode is `/usr`. However, in`macOS` as an example, you cannot write to `/usr` without `sudo` permission.
#### Proposed solution:
Enable changing the value to `/usr/local` (or any other path). This change makes the script use the value of the environment variable `SYSTEM_INSTALL_PREFIX` to select the installation path. If the variable is not set, it fallback to the path `/usr`.

### What this change is doing?
This change aims to enable us to set the `VENDORED_PATH` as an environment variable and failback to the default value if the environment variable is not set. Thus, this change should not break current behavior.
### Why we need this?
This will enable using the script to build libgit2 form source code downloaded manually.
Example:
```sh
LIBGIT2_VER="1.0.1"
DOWNLOAD_URL="https://codeload.github.com/libgit2/libgit2/tar.gz/v${LIBGIT2_VER}""
LIBGIT2_PATH="${HOME}/libgit2-${LIBGIT2_VER}"
wget -O "${LIBGIT2_PATH}.tar.gz" "$DOWNLOAD_URL"
tar -xzvf "${LIBGIT2_PATH}.tar.gz"
VENDORED_PATH=$LIBGIT2_PATH sh ./script/build-libgit2.sh --static
```
