bff4e3ce16 set_cmnd_path: apply runchroot if set when finding the command path
Previously we would prepend runchroot to the path we were checking
but that does not properly handle symbolic links.

1e0bb704c2 Restore the line that set errno to ENOENT when find_path() fails.
This was inadvertently removed when the "goto bad" was added.

0274a4f3b4 sudoedit: do not permit editor arguments to include "--" (CVE-2023-22809)
We use "--" to separate the editor and arguments from the files to edit.
If the editor arguments include "--", sudo can be tricked into allowing
the user to edit a file not permitted by the security policy.
Thanks to Matthieu Barjole and Victor Cutillas of Synacktiv
(https://synacktiv.com) for finding this bug.

d15e117c2e find_editor: remove the env_error argument
There is no case where we should fail to find an editor just because
the values of EDITOR, VISUAL and SUDO_EDITOR are unavailable.  Both
sudoedit and the "env_editor" sudoers setting are documented as
falling back on the hard-coded list of editors in the "editors"
sudoers setting.  Bug #1000

Fixes a leak when evaluating the policy multiple times if sudoedit
is set.

aeef6db85e Support EDITOR environment variable that includes quotes.

Also handles characters escaped with a backslash.

b6dbfe5094 Take the chroot into account when search for the command.
This could a a user-specific chroot via the -R option, a runchroot
Defaults value, or a per-command CHROOT spec in the sudoers rule.

446ae3f507 Include string.h unconditionally and only use strings.h for strn?casecmp()
In the pre-POSIX days BSD had strings.h, not string.h.
Now strings.h is only used for non-ANSI string functions.

dd88460800 We no longer need to include headers we don't use for sudo*.h files.
Previously we needed to include headers required by the various
sudo*h files.  Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.

ac13264b44 Use a common function for resolviong the user's editor in sudoedit
and visudo.  The find_path() function now returns a dynamically
allocated path instead of using a static string.
