This is required for the RString to std::string migration.
Mostly automated from https://github.com/aeubanks/rewriter/blob/main/c_str.cc, with some manual intervention required for fixing up `a + b.c_str()` to `(a + b).c_str()`.
Added some overloads for some common global functions like sm_crash to reduce the number of changes required here.
- Remove checking for standard functions from the build system
- Prefix all invocations with std::
- Replace suffixed functions with unprefixed versions
- Include <cmath> in all files that use it and remove the global include
e.g. floorf(x) -> std::floor(x)
This is meant to be a safer alternative since
NULL can often be 0. Let's not rely on that.
And yes, I know this is a lot of files. This is
a safer thing to do in big commits vs for loops.
