Support querying POSIX string configuration values (similar to sysconf()). confstr() is required by the POSIX_SINGLE_PROCESS Option Group as detailed in Section E.1 of IEEE-1003.1-2017 and has been part of the specification since POSIX-2. The POSIX_SINGLE_PROCESS Option Group is required for PSE51, PSE52, PSE53, and PSE54 conformance, and is otherwise mandatory for any POSIX conforming system as per Section A.2.1.3 of IEEE-1003-1.2017. With this, we have complete support for the POSIX_SINGLE_PROCESS Option Group. Signed-off-by: Christopher Friedt <[email protected]>
