Make headers self-contained by fixing `#include`s Header files are now self-contained, which makes the relationships between the files clearer, and crucially allows LSP tools like `clangd` to function correctly in all of our header files. I have verified that the headers are self-contained (aside from the various Windows shims) by compiling them as if they were C files – in a follow-up commit I plan to add this to CI to ensure we don't regress on this front. 2023-06-10 08:37:47 +08:00			`#include "jemalloc/internal/jemalloc_preamble.h"`

Make eligible global variables `static` and/or `const` For better or worse, Jemalloc has a significant number of global variables. Making all eligible global variables `static` and/or `const` at least makes it slightly easier to reason about them, as these qualifications communicate to the programmer restrictions on their use without having to `grep` the whole codebase. 2023-05-19 01:22:58 +08:00			`extern const char *const dss_prec_names[];`
