Michael Egli ff448e3485 Fix some UB cases. Closes #546 
There are two cases of UB that are fixed in this commit.

1. In ethercatmain.c, there are two left shifts of 31:

    (1 << 31)

Because 1 is a signed int by default, the result cannot be represented
in an int. The fix is to explicitly make the 1 unsigned.

2. In ethercatconfig.c, for slaves that have no inputs, the code would
   apply an offset to a NULL pointer. The fix is to test that the slave
   has inputs available before applying the offset.

Both cases were found by clang with the help of UBSan.

Wanga 9fef1fc23c Add group checking for slave input offset calculation 
Some slaves can be at different group and do not use overlap PDO map,
Let ec_config_overlap_map_group only change the input offset for current group.

Fix bug in ecx_readIDNmap(), Osize and Isize 
Osize and Isize where reset to 16 at every new drive number, thus loosing all lower drive mapping data. Changed to add 16 to Osize and Isize.

Andreas Karlsson 101ac54a7d Don't always include optional IP parameter lengths 
Obvious fix, the optional IP parameters length should
only be included in total length if they are included.

Andreas Karlsson 093311561c Limit expected working counter per ESC 
Add one to the expected working counter per
ESC/Slave, not for every syncmanager/fmmu.
Use case, if the slave define more input/output
syncmanager/fmmus it still only generate maximum
working counter of 3 for a RW command.

Schlumpf 787cf82d7d Add possibiliy to set endian target by hardware layer 
Now it is possible to set a EC_LITTLE_ENDIAN or EC_BIG_ENDIAN in the
osal_defs.h file or by compile option. If no endian is defined, the default
EC_LITTLE_ENDIAN is used.

Schlumpf 8f2b233837 Endian fixes (#222) 
This patch fixes some bugs on big-endian systems.
  - Use temp variables for etohs() and etohl() at function calls to avoid
    multiple function calls for one value.
  - Fix and add use of etohs(), etohl(), htoes() and htoel().
  - Fix use of 32bit values in 64bit variables.
