Emulator: Use libc.so bounds to fast-reject non-malloc addresses
...
The auditing code always starts by checking if we're in one of the
ignored code ranges (malloc, free, realloc, syscall, etc.)
To reduce the number of checks needed, we can cache the bounds of
the LibC text segment. This allows us to fast-reject addresses that
cannot possibly be a LibC function.

UserspaceEmulator: Don't set the MmapRegion malloc-block bit too early

We were setting it before the malloc metadata had been instantiated.
Fixes #5707 .

UserspaceEmulator: Don't assume entire malloc block is chunked
...
Accesses in the header (or trailing padding) of a malloc block should
not be associated with any mallocation since only the chunk-sized slots
actually get returned by malloc.
Basically, allow address-to-chunk lookup to fail, and handle such
failures gracefully at call sites.
Fixes #5706 .

UserspaceEmulator: Defer marking MmapRegion as malloc block
...
We don't want to audit accesses into the region *while* we're setting
up malloc tracking for it. Fetching the chunk size from the header
was tripping up the auditing code.

Kernel+UserspaceEmulator: Add sys$emuctl() system call

This returns ENOSYS if you are running in the real kernel, and some
other result if you are running in UserspaceEmulator.
There are other ways we could check if we're inside an emulator, but
it seemed easier to just ask. :^)
