 fix selection rendering issues if rounding leads to left-out pixels
 instead of manual qFloor, use the toAlignedRect() function to get the minimal enclosing rectangle
 this will in some cases over-paint one-pixel, which is preferable to under-paint which
 leaves gaps inside painting text lines that can not be fixed by the user of the painting routines

 [patch] mysql: free the results when qsqlquery::finished() is called

Calling mysql_stmt_free_result() frees the results of the last
executed query while keeping the prepared statement valid. This
allows one to keep around prepared QSqlQueries without the overhead
of keeping all the results in memory.

 fix crash when text contains too many directional chars
 In case a text to be layouted contains more than 128 directional characters
 it causes the application to crash.
 .
 The function initScriptAnalysisAndIsolatePairs() collects information of
 RTL/LTR chaaracters into vector "isolatePairs". The size of the vector is
 capped to 128. Later the function generateDirectionalRuns() iterates
 the text again and tries to access items from the previously capped vector
 above the upper bound.

 ensure that qtabletevent is not pre-accepted before sending
 In QWidget-world it's normal for input events to have the accepted
 flag false by default, so that it's obvious after visiting a widget
 subclass that does not override a particular handler function that it
 did not handle that event type at all.  For tablet events in
 particular, the contract (to which we've been paying more attention to
 ensure that QTBUG-47007 remains properly fixed) is that if a
 QTabletEvent is not accepted, a mouse event will follow.
 Tablet-unaware applications need to get the same mouse events from a
 Wacom stylus as they would receive from an actual mouse.
 .
 In this case the issue was missing hover events (mouse movements
 in which no mouse button is pressed).  Without those, the enterEvent
 and exitEvent virtuals are also not invoked properly.

 qstylesheetstyle::repolish: only run on direct children
 When re-parenting, some widgets change their children. For example
 QLabel, when set to rich text, will not update, until receiving a polish
 call, at which time getting a list of all children recursively and then
 trying to call functions on them will crash, since the children change
 in the middle of this operation.

 qlibrary/unix: do not attempt to load a library relative to $pwd
 I added the code in commit 5219c37f7c98f37f078fee00fe8ca35d83ff4f5d to
 find libraries in a haswell/ subdir of the main path, but we only need
 to do that transformation if the library is contains at least one
 directory separator. That is, if the user asks to load "lib/foo", then we
 should try "lib/haswell/foo" (often, the path prefix will be absolute).
 .
 When the library name the user requested has no directory separators, we
 let dlopen() do the transformation for us. Testing on Linux confirms
 glibc does so:
 .
 $ LD_DEBUG=libs /lib64/ld-linux-x86-64.so.2 --inhibit-cache ./qml -help |& grep Xcursor

 avoid DoS attacks when a user loads untrusted content.

 fix ambiguous definition of atime/mtime/ctime on alpha
 One of the implementations is enabled when the stat struct has
 ::st_atim member, another  when it has ::st_atimensec member.
 .
 On alpha, the stat struct has both members, defined as union here:
 https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/alpha/bits/stat.h#l48
 .
 and then used here:
 https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/alpha/bits/stat.h#l92
 .
 This patch forcefully disables the second implementation on alpha.

 revert upstream commit that removes use of syscall() and statx(2)
 The commit https://code.qt.io/cgit/qt/qtbase.git/commit/?id=b7887f9b4faad222
 removes the use of the above mentioned syscalls. This makes Qt not able
 to run on current stable servers under a testing/unstable VM.
 .
 This patch should be removed in testing/unstable after Buster gets released.
