David Gow 35c1bbfa49 SDL_stdinc.h: Add an SDL_clamp() function
Add a function to clamp a value to a range.

SDL_clamp(x, a, b) is equivalent to SDL_min(a, SDL_max(x, b)): it
ensures that x is not smaller than a, nor larger than b.

While, as best I can tell, this isn't actually standardised anywhere,
it's a very useful function/macro to have.

Joshua Root 9bf6557585 Correctly check for bswap builtins before using
The __clang_major__ and __clang_minor__ macros provide a marketing
version, which is not necessarily comparable for clang distributions
from different vendors[1]. In practice, the versioning scheme for
Apple's clang is indeed completely different to that of the llvm.org
releases. It is thus preferable to check for features directly rather
than comparing versions.

In this specific case, __builtin_bswap16 was being used with older
Apple clang versions that don't support it.

stdinc: Silence clang warning for -Wimplicit-fallthrough.
In a more ideal world, we'd use the appropriate `__attribute__` here, but
it's one thing in a public header that probably shouldn't be there at all, so
this is good enough for now.

Fixes #4307.

Misa dfe219ec71 Add all missing "is characteristic" stdlib functions
SDL has been missing a bunch of these 'isX' functions for some time,
where X is some characteristic of a given character.

This commit adds the rest of them to the SDL stdlib, so now we have:
- SDL_isalpha()
- SDL_isalnum()
- SDL_isblank()
- SDL_iscntrl()
- SDL_isxdigit()
- SDL_ispunct()
- SDL_isprint()
- SDL_isgraph()

Jay Petacat f443a6fc7a Fix format string warnings for width-based integers
The DJGPP compiler emits many warnings for conflicts between print
format specifiers and argument types. To fix the warnings, I added
`SDL_PRIx32` macros for use with `Sint32` and `Uint32` types. The macros
alias those found in <inttypes.h> or fallback to a reasonable default.

As an alternative, print arguments could be cast to plain old integers.
I opted slightly for the current solution as it felt more technically correct,
despite making the format strings more verbose.

Ryan C. Gordon 6aec6da4c3 stdinc: Let Clang static analysis see more C runtime functions.
For systems without strlcpy and strlcat, just declare them as if they exist;
the analyzer possibly still knows the details of these functions and can
utilize that in its analysis.

Most of this patch was from meyraud705 at gmail and Martin Gerhardy. Thanks!

Fixes Bugzilla #5163.

Sam Lantinga 73f2c5413d Fixed bug 2885 - SDL_stdinc.h doesn't need to include iconv.h
Ryan C. Gordon

We still include iconv.h in SDL_stdinc.h, probably because this header might have referenced the native iconv functions and types directly. Since these are hidden behind a stable ABI now and never just a #define for the system iconv, we shouldn't need this header included from a public SDL header anymore, slowing down external apps compiles and pulling tons of stuff into the namespace.

Sam Lantinga b7e45f8a1a Fixed bug 3336 - Failure to build with MinGW-w64
Kai Sterker
There are already patches available from mingw64 that fix the issue

https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-SDL2

With those applied, I could compile SDL2 without problems. But of course, it would be preferable if SDL built cleanly from source.
