Changes in v3:
* Rewrite of `strip_last_component()` as the v2 verison didn't properly handle
inputs like '/foo'. Thanks to Johannes for pointing this out and suggesting
a solution.
* Small style changes
* Revert the call in `get_common_dir_noenv()` to maintain proper functionality.
Brandon Williams (4):
real_path: resolve symlinks by hand
real_path: convert real_path_internal to strbuf_realpath
real_path: create real_pathdup
real_path: have callers use real_pathdup and strbuf_realpath
