* src/pic/device.h: removed AssignedMemory structure and macros

* src/pic/device.h: removed AssignedMemory structure and macros
* src/pic/device.c: removed global finalMapping (linker assigns
    memory locations),
  (register_map): add SFRs to remembered memRanges
  (addMemRange,isSFR,dump_map,dump_sfr,mapRegister,assignRegister,
  assignFixedRegisters,assignRelocatableRegisters): removed,
  (setMaxRAM,validAddress): adapted accordingly,
  (pic14_hasSharebank,pic14_getSharedStack): only report and use
    reasonably sized sharebanks,
* src/pic/ralloc.c (writeUsedRegs): stripped down (remove?),
  (allDefsOutOfRange): removed unused code,
* src/pic/main.c (_process_pragma): removed memmap/maxram pragma
    handling
* src/pic/pcode.c (register_reassign): removed recursion warning,
    fired far too often,
* src/pic/glue.c (emitSymbolToFile,pic14_constructAbsMap): modified
    to use existing pic14_stringInSet() to avoid duplicate symbols,
    tidied up the code a bit,
  (pic14printLocals): added in symmetry to printExterns, replaces
    writeUsedRegs more or less,
  (picglue): call new pic14_printLocals(),
* device/include/pic/pic*.h: removed #pragma memmap directives,
    information gathered from include/pic/pic14devices.txt
* support/scripts/inc2h.pl: do not emit #pragma memmap lines
