(?J) inside a pattern string can be used to allow or disallow duplicated
capturing group names in the pattern string itself.
Although PCRE supports duplicated names, in Qt we don't yet.

It may be useful to know which named capturing groups are defined
in an regular expression, and for each of them, what's the
corresponding index. This commit adds the needed method
to QRegularExpression.
Note that extracting the information doesn't happen while holding
the mutex in the private -- pcre_fullinfo just reads information
from the compiled pattern, so that's thread-safe.

This match type doesn't do any match at all; it's only necessary to
properly introduce default constructors for QRegularExpressionMatch
and QRegularExpressionMatchIterator (since they return the match type
that created them).

Check that the regular expression, the match type and the match options
returned by QRegularExpression/QRegularExpressionIterator are the

These types are either built-in or 'automatically declared' and so
don't need to be explicitly declared as metatypes.

Qt 5.0 beta requires changing the default to the 5.0 API, disabling
the deprecated code. However, tests should test (and often do) the
compatibility API too, so turn it back on.

Although passing a null pointer to pcre16_get_stringnumber for
the compiled pattern should simply make it error out, it's actually
an undocumented behaviour, so let's stay safe and add an explicit
check.
Tests for this codepath are added.

PCRE's JIT uses by default 32K on the pcre_exec caller's stack. This
is fine for most situations, but in some cases (esp. patterns with
lot of recursion) more memory is required.
Therefore, if a match execution fails due to exhausting JIT memory,
we let PCRE allocate up to 512KB to be used for the JIT's stack.
The pointer to the allocated memory is put in thread local storage
(so it can be reused from the same thread, if needed, and automatically
goes away when the thread dies).

Exporting the counter that controls the optimization of a compiled
pattern lets us to forcibly optimize all patterns. Therefore,
two tests are now run: one with default optimization values
and another one which always optimizes the pattern.
The counter itself was renamed with a qt_ prefix and put
inside the Qt compilation namespace
(thanks to rohanpm for pointing it out).

Some minor fixes: obviously, a valid match always come from a
valid regular expression, but a valid regular expression can create
an invalid match (internal error during matching).
Also, testing an invalid iterator should silence the emitted
warnings.
