Following the Security Technical Implementation Guide, it is better to
set the permissions to 0000 for the shadow file.
However, since PAM version 1.6.0, after this change [0], unix-chkpwd
will unconditionnaly read the shadow file. And with the previous
restriction, the binary has an access denied to the shadow which
blocks user authentications. Moreover the PAM changes is needed to fix
the CVE-2024-10041.
Giving the read caability to the unix-chkpwd profile allows it to
function properly. See bug report [1].

Creates an AA profile for ProFTPD. The profile has been tested on Oracular with version `1.3.8.b+dfsg-2ubuntu1`, using the source integration/unit tests and via FTP commands. As an FTP package any directory can be used for manipulating files. I've included read/write permissions to several usual locations located at the end of the profile. However these are too loose, any suggestions for how they could be tightened is much appreciated. Thanks!

Add AA profile for ghostscript. This profile has been tested on the latest plucky gs version 10.05.0dfsg1-0ubuntu1 while the latest upstream version is 10.05.0. This profile limits file access (read and write) to specific file extensions, printer devices in /dev and directories in /tmp.
The profile has been tested against the regression test suite we use in Ubuntu and manually. Testing against devices has been performed in a limited fashion as I only have access to one usb printer.

Add AA profile for `nslookup`. This profile has been tested on the latest plucky `nslookup` version `9.20.4-3ubuntu1` (ultimately part of `dnsutils`). Functionality has been exercised as much as possible, including basic record lookups, querying specific DNS servers, performing reverse DNS lookups, querying a CNAME, querying an MX record, querying a txt record, querying a DNSSEC-related record, performing IPv4 & IPv6 lookups, and overriding to use a custom resolver. These tests were performed through command parsing and the interactive terminal mode. AFAIK, upstream does not have a test suite available for `nslookup`

Have the parser extract the attachment path from the profile declaration
and make it available as a local variable within the profile. This allows
profile rules to use the executable attachment path in rules.
eg.
```
profile ex /bin/** {
@{attach_path} r,
# ...
}
profile /path/to/bin {
@{attach_path} r,
# ...
}
```
if a profile does not define an attachment like
```
profile noattach {
@{attach_path} r,
}
```
the apparmor_parser will fail the compile with the error.
```
Found reference to variable attach_path, but is never declared
```
While not recommended for rules directly in a profile the above
the undeclared variable error can be avoided in in abstractions
by wrapping the variable in a conditional.
```
if defined @{attach_path} {
@{attach_path r,
}
```
The attachment xattr/label conditionals are not made available at
this time as regular file path rules can not use them.
Similarly a @{exec_path} variable is made available. It is different
than @{attach_path} in that it is intended to be a kernel variable
that represents the specific executable that was matched at run
time. However to support policy on kernels that don't define the
kernel variable it has a fallback value that is the same as
@{attach_path}.
This patch is a follow on to MR:1637 (https://gitlab.com/apparmor/apparmor/-/me\
rge_requests/1637)
and is similar to how the apparmor.d project uses the manually setup
@{exec_path} variable.
We can bike shed over the variable name. @{attach_path} was chosen
here because this is the attachment conditional path for the
executable, not the executable's actual path. While @{exec_path} is
intended to be the applications actual executable path.
support the @{exec_path} kernel variable (all of them atm).
Notes:
The minimize.sh tests are changed because this patch causes path based
profile names to create an attachment. This could be done by doing the
attach_variable expansion in the alternate location marked by the
patch, but since the kernel is going to start doing this for all
profiles that don't have an attachment it is better for the parser to
do it, as it can optimize better.
This patch series may cause breakage if policy declares either
@{attach_path} or @{exec_path} by shadowing those previously declared
variables in the profile block. The previously declared variable
is available in the attachment specification so uses like the
apparmor.d project won't break as it with transfer its variable
value to the attachment which will the transfer that value into
the automatic local var.

Due to how labeling is implemented, during the creation it is not yet

Make it so the @{exec_path} and @{attach_path} variables behavior
completely as local variables, overriding global variables of the
same name, instead of conflicting with them.
The exec var is only validate for the profile block after the attachment
is defined so the pattern
@{exec_path}=/path
profile test @{exec_path} {
@{exec_path} rw,
}
is valid with the global var defining the attachent which then sets
the local auto @{exec_path} and @{attach_path} variables.
