Add a standalone grep application under apps/system/grep/. It uses the NuttX libc regex library (regcomp/regexec) to support -i, -n, -v, -r, -H and -h options plus stdin input and recursive directory search. SYSTEM_GREP depends on LIBC_REGEX, so the regex library must be enabled first -- CONFIG_SYSTEM_GREP only becomes selectable once LIBC_REGEX is turned on.
