The issue has been introduced when refactoring QByteArray::count
implementation (see 631127126c).
Because the last argument of QByteArrayMatcher::indexIn() method
has a defult value, it has been compiling without issues, but was being
called with incorrect size parameter. Fixed it to pass the length of the
input data correctly.

Created a QByteArrayView in symmetry with QStringView.
Added the basic tests symmetrical to QStringView tests.
Moved the implementations of non-modifying methods of QByteArray to
namespace QtPrivate, to be reused inline from both QByteArray and
QByteArrayView. Changed QByteArray's counterparts of those methods to
take QByteArrayView as argument instead of QByteArray. Removed
QByteArray's operator QNoImplicitBoolCast(), because it was causing
ambiguity when calling those methods with QByteArray argument (it was
there to perevnt if(!ba)/if(ba) from compiling, but currently that would
be ambiguous and won't compile anyway).

The recently-added slice() method has the problem that it's a noun
as well as a verb in the imperative. Like std::vector::empty, which
is both an adjective and a verb in the imperative, this may cause
confusion as to what the function does. Using the passive voice form
of slice(), sliced(), removes the confusion. While it can be read as
an adjective, too, that doesn't change the meaning compared to the
verb form.

QString and QStringRef did bounds checking for left/right/mid, whereas
QStringView was asserting on out of bounds.
Relax the behavior for QStringView and do bounds checking on pos/n
as well. This removes a source of potentially hidden errors when porting
from QStringRef (or QString) to QStringView.
Unfortunately, one difference remains, where QByteArray::left/right()
behaves differently (and somewhat more sane) than QString and
QStringRef. We're keeping the difference here, as it has been around
for many years.
Mark left/right/mid as obsolete and to be replaced with the new

In some places QByteArray does interpret bytes as characters and a
sequence of them as a text string; everywhere else, however, it now
refers to them as bytes.
Add a section to the class doc explaining how char* pointers are
interpreted; the handling of '\0'-termination is surely familiar to
most readers, but making it explicit provides contrast for the
explanation of there being no such special treatment of '\0' bytes
when a stard address and length are given.
Also mention in the class doc that interaction with QString is done
via UTF-8 encoding and can be avoided by defining a macro. Shorten, in
light of that, the description of that encoding where it appears in
affected methods.
In the process, clean up lots of phrasings.

A few pet peeves, a bunch of missing details and some phrasing I like
better.
Telling folk you're using "base 10" in fact communicates no
information; it *assumes* a base that folk shall read that text with
and tells them they are indeed using that. If they happen to be
reading with a different assumption than you, they'll duly see you
confirming their expectation. If you mean "base ten", say so.
Values "between 2 and 36" may nor may not include the bounds,
depending on weird cultural cues and contextual complications. Be
explicit about octal being base 8 and hexadecimal being base 16; most
readers shall know, but best to be clear. Be explicit about the digits
used for bases beyond ten.
Mention that QLocale is the way to do locale-sensitive conversions.

Since it's definitely surprising, add a note in the docs, which
is "somehow" consistent with the interpretation of capacity as
the biggest possible size before we reallocate. Since it's 0,
any manipulation of the size will cause a reallocation.

requested from the free store. No memory was allocated, so 0...)
