Imported at commit 80e40f57d99f ("add comment about finding latest
version of code") from:
https://github.com/rust-lang/rustc-demangle/blob/main/crates/native-c/src/demangle.c
https://github.com/rust-lang/rustc-demangle/blob/main/crates/native-c/include/demangle.h
There is discussion of this issue motivating the import in:

Following Migual Ojeda's suggestion comments were added on copyright and
keeping the code in sync with upstream.
The files are renamed as perf supports multiple demanglers and so
demangle as a name would be overloaded.
The work here was done by Ariel Ben-Yehuda <ariel.byd@gmail.com> and I
am merely importing it as discussed in the rust-lang issue.
