Fix fallback implementations of SDL_strchr and SDL_strrchr for '\0'
strchr and strrchr return a pointer to the first/last occurrence of a
character in a string, or NULL if the character is not found. According
to the C standard, the final null terminator is part of the string, and
it should thus be possible to get a pointer to the final null with
these functions. The fallback implementations of SDL_strchr and
SDL_strrchr would always return NULL if trying to find '\0', and this
commit fixes that.

stlib: Extract SDL_memcpy and SDL_memset to its own file respectively
This is done such that we can disable LTO for these 2 functions when
building with MSVC.
This is due to a limitation of Link Time Code Generation (LTCG).
Code generation might generate a new reference to memset after linking
has started. The LTCG must make assumptions about where memset is
defined which is normally the C runtime.

Add and use `SDL_FALLTHROUGH` for fallthroughs
Case fallthrough warnings can be suppressed using the __fallthrough__
compiler attribute. Unfortunately, not all compilers have this
attribute, or even have __has_attribute to check if they have the
__fallthrough__ attribute. [[fallthrough]] is also available in C++17
and the next C2x, but not everyone uses C++17 or C2x.
So define the SDL_FALLTHROUGH macro to deal with those problems - if we
are using C++17 or C2x, it expands to [[fallthrough]]; else if the
compiler has __has_attribute and has the __fallthrough__ attribute, then
it expands to __attribute__((__fallthrough__)); else it expands to an
empty statement, with a /* fallthrough */ comment (it's a do {} while
(0) statement, because users of this macro need to use a semicolon,
because [[fallthrough]] and __attribute__((__fallthrough__)) require a
semicolon).
Clang before Clang 10 and GCC before GCC 7 have problems with using
__attribute__ as a sole statement and warn about a "declaration not
declaring anything", so fall back to using the /* fallthrough */ comment
if we are using those older compiler versions.
Applications using SDL are also free to use this macro (because it is
defined in begin_code.h).
All existing /* fallthrough */ comments have been replaced with this
macro. Some of them were unnecessary because they were the last case in
a switch; using SDL_FALLTHROUGH in those cases would result in a compile
error on compilers that support __fallthrough__, for having a
__attribute__((__fallthrough__)) statement that didn't immediately
precede a case label.

Fix casts that should be using uintptr_t
This is needed to support CHERI, and thus Arm's experimental Morello
prototype, where pointers are implemented using unforgeable capabilities
that include bounds and permissions metadata to provide fine-grained
spatial and referential memory safety, as well as revocation by sweeping
memory to provide heap temporal memory safety.
On most systems (anything with a flat memory hierarchy rather than using
segment-based addressing), size_t and uintptr_t are the same type.
However, on CHERI, size_t is just an integer offset, whereas uintptr_t
is still a capability as described above. Casting a pointer to size_t
will strip the metadata and validity tag, and casting from size_t to a
pointer will result in a null-derived capability whose validity tag is
not set, and thus cannot be dereferenced without faulting.
The audio and cursor casts were harmless as they intend to stuff an
integer into a pointer, but using uintptr_t is the idiomatic way to do
that and silences our compiler warnings (which our build tool makes
fatal by default as they often indicate real problems). The iconv and
egl casts were true positives as SDL_iconv_t and iconv_t are pointer
types, as is NativeDisplayType on most OSes, so this would have trapped
at run time when using the round-tripped pointers. The gles2 casts were
also harmless; the OpenGL API defines this argument to be a pointer type
(and uses the argument name "pointer"), but it in fact represents an
integer offset, so like audio and cursor the additional idiomatic cast
is needed to silence the warning.

Fixed bug 5022 - SDL_iconv_string can get stuck in an infinite loop when encountering invalid characters
ciremo6483
In `SDL_iconv_string` the `while (inbytesleft > 0)` loop can end up in a state where it never terminates because the library `iconv` function called from `SDL_iconv` doesn't consume any bytes.
This happened when a `WCHAR_T` input string was being converted to `UTF-8` but contained invalid characters. It would first It would first skip a few bytes due to `case SDL_ICONV_EILSEQ` but when there were 3 bytes remaining of `inbytesleft` `iconv` just didn't consume anything more (but didn't throw an error either).
It just so happens that the Microsoft Classic IntelliMouse `product_string` contains such invalid characters (`"Microsoft? Classic IntelliMouse?"`), meaning the function would get stuck with said mouse plugged in.
A fix for this would be to check if `inbytesleft` was unchanged after an iteration and in that case either decrement the counter like when `SDL_ICONV_EILSEQ` is returned or simply break the loop.

Fixed bug 4283 - SDL's version of memset is different from libc's
janisozaur
memset's documentation reads:
* The memset() function shall copy c (converted to an unsigned char) into each of the first n bytes of the object pointed to by s. (http://pubs.opengroup.org/onlinepubs/9699919799/functions/memset.html)
* Sets the first count characters of dest to the character c. (https://msdn.microsoft.com/en-us/library/1fdeehz6.aspx)
* write a byte to a byte string (https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/memset.3.html)
The highlight here is they all mean a single _byte_, even though memset receives a parameter of type int, which can hold more data than a single byte. SDL's implementation of memset, however, does not clear any of the higher bits, causing an erroneous behaviour when passed an argument bigger than 0xff.

make sure SDL_vsnprintf() nul terminates if it is using _vsnprintf
The change makes sure that SDL_vsnprintf() nul terminates if it is
using _vsnprintf() for the job.
I made this patch for Watcom, whose _vsnprintf() doesn't guarantee
nul termination. The preprocessor check can be extended to windows
in general too, if required.
Closes bug #3769.
