Add new methods "subView" to O(U)String to return substring views
of the underlying data.
Add a clang plugin to warn when replacing existing calls to copy()
would be better to use subView().

...from which an OString can cheaply be instantiated.
The one downside is that OStringLiteral now needs to be a template abstracting
over the string length. But any uses for which that is a problem (e.g., as the
element type of a containers that would no longer be homogeneous, or in the
signature of a function that shall not be turned into a template for one reason
or another) can be replaced with std::string_view, without loss of efficiency
compared to the original OStringLiteral, and without loss of expressivity (esp.
with the newly introduced OString(std::string_view) ctor).
The new OStringLiteral ctor code would probably not be very efficient if it were
ever executed at runtime, but it is intended to be only executed at compile
time. Where available, C++20 "consteval" is used to statically ensure that.
The intended use of the new OStringLiteral is in all cases where an
object that shall itself not be an OString (e.g., because it shall be a
global static variable for which the OString ctor/dtor would be detrimental at
library load/unload) must be converted to an OString instance in at least one
place. Other string literal abstractions could use std::string_view (or just
plain char const[N]), but interestingly OStringLiteral might be more efficient
than constexpr std::string_view even for such cases, as it should not need any
relocations at library load time. For now, no existing uses of OUStringLiteral
have been changed to some other abstraction (unless technically necessary as
discussed above), and no additional places that would benefit from
OUStringLiteral have been changed to use it.
sal/qa/rtl/strings/test_ostring_concat.cxx documents some workarounds for GCC
bug <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96878> "Failed class template
argument deduction in unevaluated, parenthesized context". Those places, as
well as uses of OStringLiteral in incodemaker/source/javamaker/javaoptions.cxx
and i18npool/source/breakiterator/breakiterator_unicode.cxx, which have been
replaced with OString::Concat (and which is arguably a better choice, anyway),
also caused failures with at least Clang 5.0.2 (but would not have caused
failures with at least recent Clang 12 trunk, so appear to be bugs in Clang that
have meanwhile been fixed).
This change also revealed a bug in at least recent Clang 12 trunk
CastExpr::getSubExprAsWritten (still to be reported to LLVM), triggered at least
in some calls from loplugin code (for which it can be fixed for now in the
existing compat::getSubStringAsWritten).
A similar commit for OUStringLiteral is planned, too.

O[U]StringView had an odd mixture of uses. For one, it was used like
std::[u16]string_view, for which directly using the latter std types is clearly
the better alternative. For another, it was used in concatenation sequences,
when neither of the two leading terms were of our rtl string-related types.
For that second use case introduce O[U]String::Concat (as std::[u16]string_view
can obviously not be used, those not being one of our rtl string-related types).
Also, O[U]StringLiteral is occasionally used for this, but the planned changes
outlined in the 33ecd0d5c4fff9511a8436513936a3f7044a775a "Change OUStringLiteral
from char[] to char16_t[]" commit message will make that no longer work, so
O[U]String::Concat will be the preferred solution in such use cases going
forward, too.
O[U]StringView was also occasionally used to include O[U]StringBuffer values in
concatenation sequences, for which a more obvious alternative is to make
O[U]StringBuffer participate directly in the ToStringHelper/O[U]StringConcat
machinery.
