f22b06082e Expose the function that calculates CRC 
Having access to this function is useful in a variety of cases:

- hand-crafting PDUs for unit tests
- implementing extensions of the protocol
- reusing the code for other purposes (e.g. firmware integrity check)

ca0dd3bab3 Merge remote-tracking branch 'jonathangjertsen/update-helper-names' 2022-06-11 16:16:19 +02:00

4393c4a8a0 Update names of helper functions to show whether they call send or put_1/put_2 
I think this makes the code easier to read, since you can tell whether each
function call will actually `send` some bytes over the wire, or if it will
just `put` some bytes into the buffer.

249c4f3919 Sometimes it's useful to turn NMBS_DEBUG on, but the output is a bit of a mess if the read/write callbacks also log to the same channel. Moving the DEBUG statements in recv_msg_footer and send_msg_footer to the start of the function makes the output a bit cleaner, although it's not perfect. 
Example output before this change:

```
NMBS req -> fc 16   a 12326 q 2     b 4     regs 4660 43981 transmitted[13] = { f7, 10, 30, 26, 00, 02, 04, 12, 34, ab, cd, c2, 04, }

received[1] = { 0xf7, }
received[1] = { 0x10, }
NMBS res <- fc 16   received[4] = { 0x30, 0x26, 00, 0x2, }
a 12326     q 2received[2] = { 0xbb, 0x95, }

NMBS req -> fc 3    a 12326 q 2 transmitted[8] = { f7, 03, 30, 26, 00, 02, 3e, 56, }

received[1] = { 0xf7, }
received[1] = { 0x3, }
NMBS res <- fc 3    received[1] = { 0x4, }
b 4 received[4] = { 0x12, 0x34, 0xab, 0xcd, }
regs 466043981received[2] = { 0x96, 0x2f, }
```

after:

```
NMBS req -> fc 16   a 12326 q 2     b 4     regs 4660 43981
transmitted[13] = { f7, 10, 30, 26, 00, 02, 04, 12, 34, ab, cd, c2, 04, }
received[1] = { 0xf7, }
received[1] = { 0x10, }
NMBS res <- fc 16   received[4] = { 0x30, 0x26, 00, 0x2, }
a 12326     q 2
received[2] = { 0xbb, 0x95, }
NMBS req -> fc 3    a 12326 q 2
transmitted[8] = { f7, 03, 30, 26, 00, 02, 3e, 56, }
received[1] = { 0xf7, }
received[1] = { 0x3, }
NMBS res <- fc 3    received[1] = { 0x4, }
b 4 received[4] = { 0x12, 0x34, 0xab, 0xcd, }
regs 466043981
received[2] = { 0x96, 0x2f, }
