1) Rename cp_HLPflag -> cp_follow for consistency.
2) Use function-pointers for stat to clear up the code.
3) BUGFIX: TERMINATE THE RESULT BUFFER OF READLINK !!!
It's something I noticed earlier and it actually lead to some
pretty insane behaviour on our side using glibc (musl somehow
magically solves this).
Basically, symlinks used to contain the data of the file they
pointed to. I wondered for weeks where this came from and now
this has finally been solved.
4) BUGFIX: Do not unconditionally unlink target-files. Even GNU
coreutils do it wrong.
The basic idea is this:
If fflag == 0 --> don't touch target files if they exist.
If fflag == 1 --> unlink all and don't error out when we try
to unlink a file which doesn't exist.
5) Use estrlcpy and estrlcat instead of snprintf for path building.
6) Make it clearer what happens in preserve.
