Make headers self-contained by fixing #includes
...
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.

Implement guard pages.
...
Adding guarded extents, which are regular extents surrounded by guard pages
(mprotected). To reduce syscalls, small guarded extents are cached as a
separate eset in ecache, and decay through the dirty / muzzy / retained pipeline
as usual.

Stop checking head state in the merge hook.
...
Now that all merging go through try_acquire_edata_neighbor, the mergeablility
checks (including head state checking) are done before reaching the merge hook.
In other words, merge hook will never be called if the head state doesn't agree.

Ehooks: Fix a build warning.
...
We wrote `return some_void_func()` in a function returning void, which is
confusing and triggers warnings on MSVC.

Ehooks: Further optimize default merge case.
...
This avoids the cost of an iealloc in cases where the user uses the default
merge hook without using the default extent hooks.

Ehooks: remove arena_ind parameter.
...
This lives within the ehooks_t now, so that callers don't need to know it.

Move relevant index into the ehooks_t itself.
...
It's always passed into the ehooks; keeping it colocated lets us avoid passing
the arena everywhere.
