Viet Hung Nguyen b7817ffbd8 xdiff: renamed third-party xdiff functions ... Summary: Renamed xdiff functions to avoid linking issues when using both libgit2-sys and xdiff. When using repo_import tool (https://fburl.com/diffusion/8p6fhjt2) we have libgit2-sys dependency for importing git repos. However, when we derive blame data types, we need to use xdiff functionalities (from_no_parents: https://fburl.com/diffusion/pitukmyo -> diff_hunks: https://fburl.com/diffusion/9f8caan9 -> xdl_diff: https://fburl.com/diffusion/260x66hf). Both libgit2 and eden/scm have vendored versions of xdiff library. Therefore, libgit2-sys and eden/scm share functions with the same signatures, but have different behaviours and when we tried to derive blame, it used libgit2-sys's xdl_diff instead of eden's. This resulted in getting segfaults (https://fburl.com/paste/04gwalpo). Note: repo_import is the first tool that has tried to import both and the first to run into this issue.
