Adding support for replacing ljmps with sjmps in jumptables
generated for switch statements. For now you need to set the
environment variable SDCC_SJMP_JUMPTABLE to enable this.
Now 4 algorithms for mcs51 jumptable generation are used:
ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
addresses loaded pc-relative for up to 112 cases and stack-pushing
target addresses loaded with offset from dptr for up to 256 cases.
* src/SDCCpeeph.c: added peephole conditional labelJTInRange
* src/mcs51/main.c: adapted constants for switch table generation
* src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

Large cummulative patch for pic16 port.

to call when a stack overflow occurs,
* (malloc.h): added CVS Id tag,
* (pic18f{242,252,442,452}.h): added T0CONbits structure and
variable,
* added libc directory. The current version of LibC contains string
functions, ctype functions and macros and some functions of the
stdlib set (like malloc/free/atof/atoi etc...). All functions are to
be extensively tested in the future. Standard disclaimer here.
Library is not automatically build yet. But one can build it by
invoking 'make' inside the libc directory.
