Under Unix enable TCP_NODELAY to disable Nagel's socket algorithm
(Removes ~40ms delay on Redhat ES 6).

Support atom 'null' in odbc:param_query as database NULL value
Fix "ODBC: received unexpected info:{tcp_closed, ...}" when connection is terminating.
Fix possible access violation with 64bit ODBC.

cleaned causing the next call to param_query to missbehave.
Also corrected some test code

* ia/odbc/mysql:
Test odbc with MySQL
|
|
type casting even on 64 bit platforms
|
|
Updated test framework to also be able to test the erlang odbc application
with MySQL as database.
Made minor changes to error-handling to improve interoperability
with MySQL-drivers.

Loopback address constants are used when connecting the c-side
to the erlang-side over local socket API avoiding getaddrinfo problems,
and the {ip, loopback} option is added as a listen option on the erlang-side.
Also cleaned up the TIME_STAMP contribution.

Now supports SQL_TYPE_TIMESTAMP on the format {{YY, MM, DD}, {HH, MM, SS}}.
Thanks to Juhani Ränkimies.

ODBC now handles the types SQL_WCHAR and SQL_WVARCHAR. ODBC also has a new
connection option to return all strings as binaries and also expect strings
to be binaries in the param_query function. This provides some but not a
full unicode support.

* kr/odbc-netinet:
Fix ODBC compilation error on FreeBSD by adding netinet/in.h to #include macros
OTP-8444 The odbc application can now be compiled on FreeBSD. (Thanks to
Kenji Rikitake.)

This fix modifies lib/odbc/c_src_odbcserver.c
This has been tested on FreeBSD port, and will not affect Linux.

* po/odbc-update-delete-no-rows:
SQL_NO_DATA and SQLSTATE 00000 indicate success for updates/deletes that affect no rows

affect no rows
I noticed the following when no rows were updated for an update statement:
4> odbc:param_query(Ref, "update tbadger set status = ? where
badger_id = ?", [{{sql_varchar,1},["R"]}, {sql_integer, [61111]}]).
{error,"No SQL-driver information available."}
5> odbc:param_query(Ref, "update tbadger set status = ? where
badger_id = ?", [{{sql_varchar,1},["R"]}, {sql_integer, [61]}]).
{updated,1}
The attached patch, which requires the ODBC patch from Andrew
Thompson, should fix it:
3> odbc:param_query(Ref, "update tbadger set status = ? where
badger_id = ?", [{{sql_varchar,1},["R"]}, {sql_integer, [61111]}]).
{updated,0}
4>
I've followed the advice given on MSDN
(http://msdn.microsoft.com/en-us/library/ms715424%28VS.85%29.aspx) and
checked for SQL_NO_DATA combined with SQLSTATE 000000
