c3e794c4d0 rework string pooling; disable our own (rely on compiler’s)… 
• if HAVE_STRING_POOLING is set to 1
• if HAVE_STRING_POOLING is set to 2 and not GCC < 4 is used
• if HAVE_STRING_POOLING is not set to 0 and LLVM or GCC >= 4 is used

Closes: LP#1580348

1df3efdb86 another intermediate step/commit to get arithmetics right: 
do the correct operations for comparisons (just keep using the
signed/unsigned switch from bivui for them), division (by working
on absolutes and adding the sign at the end), modulo (stupidly by
divising in signed, multiplying and subtracting, to get the sign
of the result right)

also adds rotation

XXX to check: do we need to AND before assigning the result in division?

7cce9de0bc one can’t cast an unsigned int to a signed int portably either, if the value 
is larger than the positive range of the latter (implementation-defined), so
avoid them in all explicit cases and rearrange stuff and check for it

(I’m gonna have to revise lots more code…)

6a745a01fa begin using unsigned arithmetics internally as much as possible 
(i.e. where signedness doesn’t matter, given -fwrapv) and note
where there’s work to do; note future improvements and additions;
optimise a little

mostly untested

9646c98356 I give up on writing (1 << 31) in any form.

cf75e7b6ce couple of minor/cosmetic fixes from RT’s compile farm: 
• promote SCO OpenServer and UnixWare to !oswarn
• omit trying -O2/-O on OpenServer 5 and USL C
• cast mksh_ari_t to int, mksh_uari_t to unsigned int for printf
• skip ulimit-1 on syllable (which is still too broken)
• write ((mksh_ari_t)-2147483648) ipv UB ((mksh_ari_t)1 << 31)
  and add a comment that that is actually meant
• rewrite functions returning !void ending in NOTREACHED
  so they’ve got a jump target returning an error at the
  end, to aid older compilers and just to be safe
• cast struct stat.st_size to off_t or size_t explicitly when needed
• shorten struct env by two bytes and an alignment, at least

also, optimise control flow and fix more paren matching cases
