the standard-compliant version, so use that there.

4712d88c0e Make letter spacing APIs in QTextFormat more consistent
Change d060b6f04f introduced some
new properties to QTextFormat which were unfinished and did not
match the documentation in the same change. I've updated the API
and docs to use the regular QFont enum for letter spacing type
instead of introducing bools (which inhibits expansions later)
or mutually exclusive properties in the text format.

547a1bea49 Fix limitting shortcuts to keypad only
The Qt::KeypadModifier modifier is internally masked away from all
shortcuts. So it is not possible to set a keypad only shortcut.
Changed the implementation so that first a full keysequence match is
searched. Then if no match is found the same sequence is tried
without the keypad modifer.

Added a autotest for this also to cover the basic use cases relating
to this.

The old code resulted in one memory fetch for the test plus another one

already-loaded value:

80694dd614 moc: parse classes that use Q_DECL_FINAL|final|sealed
This only works with the C++11 contextual keyword
directly, the MSVC equivalent 'sealed', or the Qt
define for it.

While this isn't a problem for syncqt, being an
internal tool, moc should eventually be able to parse
user code using local C++11-final-wrapping macros.
For this, I guess moc would have to be taught to
expand macros in code and not just test #if clauses,
potentially driven by something like
  #pragma qt-moc expand-this
  #define MY_FINAL_CLASS final
but that's something for someone more intimately
familiar with moc's source than I am.

d811b2434b syncqt: parse classes that use Q_DECL_FINAL|final|sealed
I've introduced a variable $post_kw (post-class-keywords) that
contains the patterns which are expected after a class name.
This variable is used both for a negative look-ahead assertion
in the class-name capture (so the regex doesn't parse the
keywords as the class-name), as well as to carry the parser
over the keywords into the subclass clauses.

7e0fa2fc75 QVariant: make the HasIsNullMethod check work across all compilers (maybe)
Currently, we have a C++11 version that requires Q_COMPILER_DECLTYPE
support, and can deal with final classes, and a C++98 version that
doesn't require any C++11 features, but fails on final classes.

What we're missing is a version that works for MSVC v8 and v9
(2005 and 2008), which sport the 'sealed' non-standard keywords
but lack decltype support. So far, we tried to solve the problem
by making class-level final special (Q_DECL_FINAL_CLASS), not
defining that macro for these two compilers, even though we did
define Q_DECL_FINAL, the method-level keyword.

This new formulation, taken from
  http://stackoverflow.com/a/9655327/134841
supposedly supports all compilers with a minor #ifdef for
MSVC which doesn't like applying sizeof() the way we do.

However, testing has shown this to blow up on OSX.

So we use the less intrusive approach: add this variant as
a third version, only used by VC 2005 and 2008.

bf186ceebb qcompilerdetection.h: stream-line MSVC feature detection
Reformat the MSVC feature detection to be similar to other compilers, ie.

1. Inside the C++11 features section instead of where the compilers
   are detected
2. In one block for the compiler, with sub-blocks for the version.

However, it's now not 100% compatible with the previous version,
since Q_CC_INTEL is now explicitly excluded while before it was
implicitly included in the MSVC case. I have no idea whether
that matters, since Q_CC_INTEL is handled for itself further up
already.

c28204066c Mark mutex locking and unlocking functions with noexcept
Unlocking a mutex can never throw an exception. That doesn't make
sense and our code should make sure it can't happen. Right now,
provided that the system-level functions don't throw, we don't either.

Locking a mutex cannot throw on Linux because we use futexes
directly. A non-recursive mutex is just a futex, whereas a recursive
mutex uses a mutex (a futex) to manage a lock count.

However, on other platforms, due to the freelist, there can be memory
allocation, which means it might throw std::bad_alloc. Not because of
the freelist itself (that uses malloc and will just crash if malloc
fails) but because of Q_GLOBAL_STATIC. In 5.1, the global static will
be noexcept provided the type's constructor is so too (it is, in this
case).

Both the configure script and configure.exe add QT_NO_ICONV to qconfig.h
in case they can't find iconv. Since Windows doesn't use iconv anyway,
we don't need to set QT_NO_ICONV here.

MSVC likes to print a warning that a macro is redefined. That gets quite
spammy...

210f762f7d qdbus_loadLibDBus: remove unneeded volatile qualification
The variable is only ever accessed under mutex protection, and
doesn't otherwise look like it could be changed by the hardware,
so remove the volatile qualifier.

4d5f3cf627 Test for quadratic behaviour when rendering long line in QTextEdit
QTextEdit showing long lines using lots of text format (for example
with a syntax highlighter) used to expose a quadratic behaviour which
make it impossible to edit files with long lines.

It was fiexed in the few previous commit

c13011829f Speed up QTextEngine::setBoundary
Before, setBoundary was O(N), now it is O(log N) assuming the boundaries
are added in order. (splitItem might still be linear because of the call
to QVector::insert)

This speeds up a lot QTextEngine::addRequiredBoundaries when there is a
lot of addFormats. (For example if there is a very long line with syntax
highlighting)
