The existing code derived a helper class from QSqlResult and
overloaded two protected functions as public ones so the test
could call them after casting QSqlResults to that helper class.
Both the cast (which is a C-style cast, but with combined
static_cast and const_cast semanics) and the following member
function call are undefined behavior.
Fix by making the test class a friend of QSqlResult, and
dropping the casts.

Instead, we use the binary MySQL encoding and copy the data directly
into the QVariant of the desired type. This gets rid of the temporary
string allocations and greatly improves the performance of the added
benchmark. On my machine, the results are:
Before:
0.562 msecs per iteration (total: 563, iterations: 1000)
1,922,479.330 instructions per iteration (total: 1,922,479,330, iterations: 1000)
After:
0.381 msecs per iteration (total: 381, iterations: 1000)
774,132.957 instructions per iteration (total: 774,132,958, iterations: 1000)
Note that the same could be applied to floating point data types in
the future. Additionally, special support for MYSQL_TIME structure
coult be added to get rid of the string conversions there.
To ensure everything keeps working, a new auto test is added as well
that verifies the select statements and insertions of integral data
into a MySql table works as intended.

This patch adds correct timezone support in PSQL plugin. Prior to this
patch, no timezone support was provided, so only the following case
worked :
* using local time in both client application and postgresql server
* datetime were using second precision
This patch tries to take care that postgresql has two different
datatypes for date time, respectively :
* timestamp with time zone
* timestamp without time zone
Both are internally stored as UTC values, but are not parsed the same.
* timestamp with time zone assumes that there is a time zone
information and will parse date time accordingly, and then, convert
into UTC before storing them
* timestamp without time zone assumes that there is no time zone
information and will silently ignore any, unless the datetime is
explicitly specified as having a time zone, in case it will convert
it into UTC before storing it
Both are retrieved as local time values, with the following difference
* timestamp with time zone includes the timezone information
(2014-02-12 10:20:12+0100 for example)
* timestamp without time zone does not include it
The patch does the following :
* parse the date retrieved by postgresql server using QDateTime
functions, which work correctly
* always convert the date to UTC before giving it to postgresql
* force time zone so that timezone information is taken into account
by postgresql
* also adds the milliseconds when storing QDateTime values
The following configurations are tested to work :
* client and server using same timezone, timestamp with or without tz
* client and server using different timezone, timestamp with tz
The following configuration will *not* work :
* client and server using different timezones, timestamp without tz
Because data will be converted to local time by the postgresql server,
so when returned it will be different from what had been serialized.
Prior to this patch, it gave the illusion to work because since TZ
information was lost, time was stored as local time from postgresql.
Lots of inconsistencies occurred, though, in case client tz changes...
I don't expect this to be an issue since having different TZ in server
and client and *not* handling this is a broken setup anyway.
Almost based on changes proposed by julien.blanc@nmc-company.fr
