a401107564 Check for sudo_ldap_result_last_search() returning NULL. This can't 
happen in practice because we always call sudo_ldap_result_add_search()
first which guarantees there is a result to be found.
Quiets a PVS-Studio warning.

dbd5252798 Fix incorrect strncmp() lengths. The check for USERNAME was only 
looking at the first 5 characters (copy and paste error).  The check
for SUDO_PS1 was not checking the trailing '=' character (off by
one error).  Found by PVS-Studio.

4c8988d483 When checking for old-style bash functions in the environment, check 
for values starting with "() " (note the trailing space) rather
than "()".  Bash will only treat the value as a function if the
space after "()" is present.  The trailing space was already present
in the compare string but when it was added, the length passed to
strncmp() was not updated from 3 to 4.
Found by PVS-Studio.  No security impact.

63adb21cea Add some missing casts from uid_t/gid_t to int when printing uid/gid 
values.  We print these as signed so a value of -1 (no change) is
obvious.  Quiets PVS-Studio warnings.

cf5a12c09a def_timestamp_timeout is a double so compare against 0.0 not 0 to 
avoid making it appear to be an integer type.

e3825cbedd When checking syslog facility or priority, move the string 
compare into the body of the loop and return if it matches.
If we finish the loop it means we didn't find a match.
This makes the code a little bit more readable.

0a68d6799e Fix matching when no sudoRunAsUser is present in a sudoRole. 
If only a sudoRunAsGroup is present, match on the invoking user
if the -g option was specified and the group matched.
If no sudoRunAsGroup is present and the -g option was specified,
allow it if it matches the passwd gid of the runas user.
This matches the behavior of the sudoers backend.

ef82f792a1 Update check for whether or not the runas user was set in the ldap 
and sssd backends to match the sudoers file backend.  Introduces
the runas_user_set() macro to improve readability.  Previously,
runas_pw was set late, now it is set before checking sudoers.

3f022419ae Be consistent with the naming of the variable used to store the 
function return value.  Previously, some code used "rval", some
used "ret".  This standardizes on "ret" and uses "rc" for temporary
return codes.
