Added the stop_bits_client parameter to the modbus_serial_param struct.
Being able to configure the number of stop bits for the client
independently from the parity setting, allows to support connecting to
modbus server that do not follow the MODBUS over Serial Line Specification
and Implementation Guide.

On some platforms, if there are multiple MODBUS interfaces,
receiving of RTU frames may fail. Replacing while loop with
just "if" fixes this problem.

This patch is to fix an issue where the transceiver chip is
disabled before it has transmitted all data. This causes the
message to be corrupted because the last few bytes are missing.
The fix adds a check to make sure the transmission is completed
before disabling the transceiver.

In previous commits the crc16_ansi() function has been made compliant
with the CRC-16-ANSI aka CRC-16-MODBUS standard. Use that standard
function instead of a custom one.

Prefix internal functions and structs with modbus_.
Use unit_id consistently instead of node_addr.
Fix mbm_ remainder and rename to mbc_.
Rename struct modbus_frame to modbus_adu since
ADU is closer to what the structure represents.
Let the compiler/linker do the job and
remove ifdef around mbc_validate_fc03fp_response().
