When you are using a query that pulls from a number of different tables
then it can be ambiguous as to which table a particular field belongs to.
So this will make it possible to determine the table that a given field
belongs to if it is set.

SQLite has been supporting named placeholders for some time now and the
code of the module is also written in that sense. The only thing that
currently fails is the parameter count check. If the named placeholder
is used several times then the parameter count will not match the
value count. This patch adds a second check in that case. This use
case is already tested by tst_qsqlquery.
[ChangeLog][QtSql][SQLite] Named placeholder can now be used.
If compiling Qt by hand and using system libraries, this feature
requires at least SQLite 3.3.11.

By default SQLite opens DB in Serialized mode, allowing connections to be used
from several threads simultaneously: https://www.sqlite.org/threadsafe.html
According to Qt documentation, database can only be used from one thread.
This change opens sqlite dabases in "Multi-thread" mode, so that one does not
pay for useless mutex locking for each DB access

Since SQLite does not define a regexp function by default, provide a Qt
based implementation which can be enabled using QSQLITE_ENABLE_REGEXP as
an connect option. This way statements like
SELECT * FROM table WHERE col REGEXP '^[a-d]';
work out of the box.
[ChangeLog][QtSql] Add QSQLITE_ENABLE_REGEXP connect option for
QSQLiteDriver. If set a Qt based regexp() implementation is provided
allowing to use REGEXP in SQL statements.

Prefer QStringRef methods to avoid allocations.
Use startsWith/endsWith rather than comparing substrings;
and avoid substrings where references suffice.
Use new QStringList::join(QL1S).
