With this change, it is possible to significantly reduce memory
consumption of applications that fetch large result sets from databases.
The implementation is based on the new functionality called "single-row
mode" that was introduced in PostgreSQL version 9.2:
https://www.postgresql.org/docs/9.2/static/libpq-async.html
It also uses asynchronous commands PQsendQuery(), PQgetResult():

[ChangeLog][QtSql][QPSQL] Added support for forward-only queries (requires
libpq version 9.2 or later)
[Important Behavior Changes] The QPSQL driver now supports forward-only
queries. To use this feature, you must build QPSQL plugin with PostreSQL
client library version 9.2 or later. See the Qt SQL documentation for
more information about QPSQL limitations of forward-only queries
(sql-driver.html).
[Important Behavior Changes] If you build the QPSQL plugin with PostgreSQL
version 9.2 or later, then you must distribute your application with
libpq version 9.2 or later. Otherwise, the QPSQL plugin will fail to load.

Also on calling setMin/MaximumSectionSize() the current section sizes

What we need to do is after calling ppdMarkOption parse the tree again looking

Not all X server vendors support the XKB protocol. Furthermore,
while X.org seems to use keycodes that match the usual keyboard
scancodes, other vendors may not do so. This means that using an
XKB keymap suitable for an X.org server results in garbled input
with servers for other vendors.
Both of these issues are addressed by using the core keycode
information as a fallback.

if an XKB keymap could not be determined through the connection.

What was broken:
- m_xiGrab on successful ungrab (XIUngrabDevice) was never set to 'false'.
Which means that we would unnecessarily call XIAllowTouchEvents, even when
we are not grabbing (this did not have any apparent side effects).
What was non optimal:
- Redundant XIQueryDevice calls. XIQueryDevice with XIAllMasterDevices flag
already returns all required devices. Calling XIQueryDevice for every id again
does not make sense.
- Querying for master pointer info on every grab is unnecessary. Simply cache
ids of master devices whenever hierarchy changes.
What remains to be investigated some time later (or never):
The original and the re-factored code grabs all master pointer devices. Not
sure if that is the expected behavior on MPX (Multi-pointer X) systems. Could
there be two context menus, each dismissed separately? MPX concept was introduced
in XI2.0, but testing shows that this setup is not very well supported even on
modern desktop environments. Tested on Ubuntu 16.04, where multiple pointers is
enough for crashing a terminal. Also AFAIK there isn't any bug reports about
broken MPX support in Qt.

parts of the string contained inside an directional isolate is
to be ignored when determining the paragraph direction. Embedding
markers themselves are to be ignored as well, but not the characters
inside an explicit directional embedding or override.
This is also some required pre-work to get our BiDi algorithm
