70c75cb2db Convert get_ and put_ to functions 
This shaves off about 1 kB of flash usage from my client application.
It is also more type safe, which is nice.

80fa8ef4ae Send platform argument to nmbs_callbacks 
This is useful for the same reasons as the arg is useful in the platform callbacks.

17aa0ca226 Support disabling individual server callbacks 
This helps reduce code size for systems that do not implement the full
set of function codes supported by the library.

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, }
