rust: Use `&HgPath` instead of `&HgPathBuf` in may APIs
Getting the former (through `Deref`) is almost the only useful thing one can
do with the latter anyway. With this changes, API become more flexible for the
"provider" of these paths which may store something else that Deref’s to HgPath,
such as `std::borrow::Cow<HgPath>`. Using `Cow` can help reduce memory alloactions
and copying.

initial setup
$ cat << EOF >> $HGRCPATH

repository itself is non-readable
---------------------------------
$ hg init no-read
$ hg id ssh://user@dummy/no-read
000000000000
$ chmod a-rx no-read
$ hg id ssh://user@dummy/no-read
remote: abort: Permission denied: *$TESTTMP/no-read/.hg* (glob)
abort: no suitable response from remote hg
[255]
special case files are visible, but unreadable
----------------------------------------------
This is "similar" to the test above, but the directory is "traversable". This
seems an unexpected case in real life, but we test it anyway.
$ hg init other
$ hg id ssh://user@dummy/other
000000000000
$ for item in `find other | sort -r` ; do
> chmod a-r $item
> done
$ hg id ssh://user@dummy/other
remote: abort: Permission denied: '$TESTTMP/other/.hg/requires'
abort: no suitable response from remote hg
[255]
directory toward the repository is read only
--------------------------------------------
$ mkdir deep
$ hg init deep/nested
$ hg id ssh://user@dummy/deep/nested
000000000000
$ chmod a-rx deep
$ hg id ssh://user@dummy/deep/nested
remote: abort: Permission denied: *$TESTTMP/deep/nested/.hg* (glob)
abort: no suitable response from remote hg
[255]
repository has wrong requirement
--------------------------------
$ hg init repo-future
$ hg id ssh://user@dummy/repo-future
000000000000
$ echo flying-car >> repo-future/.hg/requires
$ hg id ssh://user@dummy/repo-future
remote: abort: repository requires features unknown to this Mercurial: flying-car
remote: (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
