c192b6c61d 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.

57142a29a0 UserspaceEmulator: Don't set the MmapRegion malloc-block bit too early 
We were setting it before the malloc metadata had been instantiated.

Fixes #5707.

1381720d1d 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.

38fc522f5d UserspaceEmulator: Don't audit accesses in calloc() and libsystem.so

a457b90733 UserspaceEmulator: Tidy up the MallocRegionMetadata construction a bit 
Use designated initializers to make it very obvious what's being set,
and also give the metadata a backpointer to the region for convenience.

915e8dbe71 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.

b940dd4fa8 UserspaceEmulator: Never try to mprotect(PROT_EXEC) MmapRegion backing 
We never want to map host memory executable anyway, so let's always
mask off the PROT_EXEC bit.

9588f01739 UserspaceEmulator+LibC: Use sys$emuctl() to pass malloc info to UE 
Get rid of the awkward secret handshake sequence between malloc and UE
and simply use sys$emuctl() to notify UE of malloc, free and realloc.

4faeaf101c LibC: Don't scrub memory in malloc/free when running in UE 
Since UE is keeping track of the heap anyway, we can skip the scrubbing
and drastically improve the speed of malloc and free when emulating.

84725ef3a5 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. :^)

68f2ef1097 Ports: Add libogg 
This library will allow us to port more multimedia programs and games,
since it's a common dependency of such projects. I was looking at
Scummvm's dependencies in particular, with a goal of porting them all
eventually, so that we can have Myst running in Serenity!

968ad0f8d1 LibWeb: Some improvements to CSS height:auto computation for blocks 
Auto block heights are now computed according to something that kinda
resembles the specification.

Blocks with inline children and height:auto have their height computed
based on the top of the first line box and the bottom of the last line
box. Very straightforward.

Blocks with block children and height:auto have their height computed
based on the top of the first in-flow block child's margin box, and the
bottom of the last in-flow block child's margin box.
