f262138572 mbus_manufacturer_id: add error checking code 
Signed-off-by: Michael Heimpold <mhei@heimpold.de>

0fccc0e337 Add a function to calculate the manufacturer ID from the 3 byte ASCII 
code. The formula can be found at http://www.m-bus.com/files/w4b21021.pdf,
chapter 3.3 at page 6.

This obsoletes the static defines, so remove them.

c848090f56 Rebuilding M-Bus context structs in progress 
- changed local library file includes from <> to ""
- get rid of 'if (is_serial)' conditions
- mbus_context_serial() and mbus_context_tcp() allocates memory and initialize context specific function pointers
- simply mbus_connect() called instead of mbus_connect_tcp() or mbus_connect_serial()
- context specific data can still be accessed via (void* auxdata) pointer
- strdup(3) to copy host IP into TCP context struct

bf12395af9 Fixed segmentation fault in case of much XML output 
Because of the multi telegrams it is impossible to use a fixed
buffer for XML output on the stack. Now the buffer is allocated on the
heap. These also leads to a change in return behaviour for all XML
functions, because it's possible that the buffer is NULL. For variable
data this buffer grows every time there are less than 1024 bytes left
for a new record.
