Make the TCP implementation "protocol independent", i.e. IPv6 capable.

This commit changes the internal data structures and functions to use the
protocol independent networking interface, i.e. "getaddrinfo(3)" and friends.

Even if you don't use IPv6, you still benefit from this change, because both
"modbus_init_tcp*" functions not support resolving hostnames. Previously, an
IPv4 address given in the dotted-decimal format as a string was necessary. Now
the system resolver is used, so you can use aliases specified in /etc/hosts,
hostnames resolved via DNS or IP addresses.

A new function, "modbus_init_tcp_pi", has been added, too. It accepts the
"service" as a string so you can also use the service name if it is present in
/etc/services.

src/modbus.[ch]: Re-indent with spaces instead of tabs.

Didn't notice that the file was indented with spaces, sorry.

src/modbus.h: Move parameters into an opaque data structure.

This makes it *a lot* easier to add features while preserving API and ABI
compatibility with later versions. The parameters are in a new struct,
"modbus_object_t", which is marshalled by "modbus_param_t". This way client
applications can still allocate the "modbus_param_t" which hopefully minimizes
required changes in client applications.

Argument checking is *not* done yet, so using libmodbus in an invalid manner
(calling functions without calling one of the "modbus_init_*" functions first)
will result in a segmentation fault.
