more of this: • shell flags are now handled in one single place (sh_flags.h) • sync comments (between enum and array) and manpage with reality • FMONITOR is now no longer needed for Hartz IV shells

To solve the incompatibility issues between mksh-current, old mksh versions and vendor pdksh versions, re-introduce FPOSIX alongside FSH. The semantics are now: ‣ set -o posix ⇒ • disable brace expansion and FSH when triggered • use Debian Policy 10.4 compliant non-XSI “echo” builtin • do not keep file descriptors > 2 to ksh ‣ set -o sh ⇒ • set automatically #ifdef MKSH_BINSHREDUCED • disable brace expansion and FPOSIX when triggered • use Debian Policy 10.4 compliant non-XSI “echo” builtin • do not keep file descriptors > 2 to ksh • trigger MKSH_MIDNIGHTBSD01ASH_COMPAT mode if compiled in • make “set -- $(getopt ab:c "$@")” construct work Note that the set/getopt one used to behave POSIXly only with FSH or FPOSIX (depending on the mksh version) set and Bourne-ish with it not set, so this changes default mksh behaviour to POSIX!

further optimise and simplify the handling of $RANDOM, reads and writes to it are now either arc4random or rand/srand, but srand retains the old state; set +o arc4random is no longer possible, but if it's there we use arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special variable handling too and fix a few consts and other minor things

change undef/def MKSH_NOVI into 0/1 MKSH_S_NOVI flag (with more to come: MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis- abled language features), which can be set to 0 despite MKSH_SMALL being defined to re-enable the Vi command line editing mode (which I wouldn't, but fits into the general mastermind scheme)
