* device/include/sdcc-lib.h: inserted LGPL, added includes

* device/include/sdcc-lib.h: inserted LGPL, added includes
  asm/ds390/features.h and asm/mcs51/features.h
* device/include/asm/default/features.h,
* device/include/asm/gbz80/features.h,
* device/include/asm/z80/features.h: added empty _AUTOMEM
  and _STATMEM
* device/include/asm/ds390/features.h,
* device/include/asm/mcs51/features.h: added files with defines for
  _AUTOMEM and _STATMEM indicating automatic and static storage class
* device/lib/printf_large.c (_print_format): optimized & used _AUTOMEM
* doc/sdccman.lyx: version 2.4.7, updated xstack documentation
* src/SDCCicode.c (geniCodeCast),
* src/SDCCsymt.c (compareType): allow cast of data-ptr to idata-ptr
* src/SDCCloop.c (loopInduction): removed unused variable lr
* src/SDCCopt.c (convilong, convertToFcall): moved "easy special case"
  to convertToFcall to include char modulo (RFE 1065037), added check
  if left operand is unsigned and use abs of literal value
* src/SDCCpeeph.c (setFromConditionArgs): removed double quotes option
  as it doesn't work after conversion from peephole.def to peephole.rul
* src/mcs51/gen.c (toBoolean): added check for size,
  (genModOneByte): optimized code for signed char modulo a literal
  power of 2 (thanks to Hubert Sack),
  (genRRC): removed unnecessary "clr c",
  (genRLC): replaced "add a,acc" with cheaper "rlc a"
* src/mcs51/peeph.def: renamed 115 to 115.a, added rule 115.b: another
  jump optimization,
  swapped rules 256.c and 256.d,
  extended 256.d by using new multiple checks (thanks Erik),
  added rules 256.e and 256.f,
  updated rule 261.a and 261.b to new generated code
* support/regression/tests/muldiv.c: added test div/mod by a power of 2
