Move SWIGStringWithLengthHelper to csharphead.swg
cdata whitespace/cosmetic fixups
cdata doc updates
Rename `typemaps/cdata_struct.swg` to `typemaps/cdata_begin.swg`. And `typemaps/cdata.swg` to `typemaps/cdata.swg`. Move `cdata_apply.swg` content to `typemaps/cdata.swg`.
Group the C# marshalling of STRING-LENGTH typemap into C# class named SWIGStringWithLengthHelper.
Leave Length & string reverse order typemap in typemaps/strings.swg
Support old C# as "LPUTF8Str" was add in 2017.
Improve documentation. Follow @wsfulton reviews.
Use a dummy for MzScheme and untested OCaml cdate. To prevent compilation error.
Further fixing follow reviews.
Reorganise raw data typemap, so typemaps folder contain only common part. Improve document.

Fix Java STRING LENGTH typemap.
Use string type in static typed languages (Java, C#, D and Go).
Add BYTES LENGTH typemap and apply it for binary data.
Use byte type in static typed languages.
Add li_cdata_cpp, li_cdata and char_binary
tests for most of languages(apart from R and experimental).
Fix the director_binary_string test and add it to C#, D, Go,
Perl, PHP, Python, Ruby and octave.
Update documents.

Order of evaluation of C++ function arguments is not defined, and if
lua_rawlen() was called before lua_tostring() then it would return 0
(because the value was still a number) and an empty string would be
passed.
The same issue affects std::string_view too, but that's not been in
a release yet.
The new testcases fail without the fix with GCC 12.2 on x86-64 Linux.
SWIG_LUA_CONSTTAB_INT can be called with a constant expression
containing commas (e.g. `SizeOf< int,int >::size`). This was
addressed in b13f584258 by making
its second argument variadic, but (a) this doesn't work with
our baseline of C90/C++98 and (b) the variadic syntax used is
a GCC extension which doesn't work with all compilers (e.g. MSVC).
We can solve this without needing variadic macros by simply wrapping
this argument in an extra pair of parentheses when calling.
Add Swig_obligatory_macros which must be called by each
target language to define SWIG_VERSION correctly
in the generated code, as well as the language specific
macro SWIGXXX where XXX is the target language name.
Drop the #ifdef SWIGXXX that was previously generated -
I can't see the point of this and if users are defining
this macro somehow, then users will need to change this
Closes#1050
Ensure that SWIG_VERSION is defined both at SWIG-time and in the
generated C/C++ wrapper code (it was only defined in the wrapper
for some target languages previously).
SWIGGO and SWIGJAVASCRIPT are now defined in the generated wrappers
to match behaviour for all other target languages.
Stop defining SWIGVERSION in the wrapper. This only happened as a
side-effect of how SWIG_VERSION was defined but was never documented and
is redundant.
The new testcase also checks that SWIG is defined at SWIG-time but not
in the generated wrapper, and that exactly one of a list of
target-language specific macros is defined.
Fixes#1050
For implementing full move semantics when passing parameters by value.
Based on SWIGTYPE && and std::unique_ptr typemaps which implement move
semantics.
Added for all languages, but untested for: Go, Ocaml, R, Scilab (and
unlikely to be fully functional for same reasons as for std::unique_ptr
support).
Issue #999
Enhance SWIGTYPE "out" typemaps to use std::move when copying
objects, thereby making use of move semantics when wrapping a function returning
by value if the returned type supports move semantics.
Wrapping functions that return move only types 'by value' now work out the box
without having to provide custom typemaps.
The implementation removed all casts in the "out" typemaps to allow the compiler to
appropriately choose calling a move constructor, where possible, otherwise a copy
constructor. The implementation alsoand required modifying SwigValueWrapper to
change a cast operator from:
SwigValueWrapper::operator T&() const;
to
#if __cplusplus >=201103L
SwigValueWrapper::operator T&&() const;
#else
SwigValueWrapper::operator T&() const;
#endif
This is not backwards compatible for C++11 and later when using the valuewrapper feature
if a cast is explicitly being made in user supplied "out" typemaps. Suggested change
in custom "out" typemaps for C++11 and later code:
1. Try remove the cast altogether to let the compiler use an appropriate implicit cast.
2. Change the cast, for example, from static_cast<X &> to static_cast<X &&>, using the
__cplusplus macro if all versions of C++ need to be supported.

More about the commit:
Added some missing "varout" typemaps for Ocaml which was falling back to
use "out" typemaps as they were missing.
Ruby std::set fix for SwigValueWrapper C++11 changes.
This was an alternate version without NULL checks on free() and
delete, but we removed those checks globally in
7ec2f89fe2 so now it's just the
same as the active code.
This is necessary for regex-like renames (where you can't use the #define trick
as is done in many of the %keywordwarn directives). It's now unnecessary to print
the "renaming to '`x`'" code explicitly by the kw.swg files.
Remove redundant NULL checks before free()/delete
The ISO C and C++ standards guarantee that it's safe to call these
on a NULL pointer, so it's not necessary for the calling code to
also check.
