59049ae4b7 Kernel: Store VMObject physical pages in a FixedArray
Let's enforce the invariant that VMObjects don't shrink or grow by
storing the pages in a FixedArray.

7d096a1287 Kernel: Make VMObject vend physical page range as a span
Stop exposing the internal data structure used for storing the physical
pages and return a Span<RefPtr<PhysicalPage>> instead.

88c8451973 AK: Bring back FixedArray<T>
Let's bring this class back, but without the confusing resize() API.
A FixedArray<T> is simply a fixed-size array of T.

The size is provided at run-time, unlike Array<T> where the size is
provided at compile-time.

846685fca2 Kernel: Remove bogus VMObject resizing in VirtIOGPU
It is not legal to resize a VMObject after it has been created.
As far as I can tell, this code would never actually run since the
object was already populated with physical pages due to using
AllocationStrategy::AllocateNow.

b2cd9b2c88 Kernel: Remove pointless ref-counting from PhysicalRegion
These are not multiple-owner objects and have no use for ref-counting.
Make them simple value types instead (not eternal heap-allocated.)

29d53cbee2 Kernel: Return correct error numbers for the mkdir syscall
Previously, VirtualFileSystem::mkdir() would always return ENOENT if
no parent custody was returned by resolve_path(). This is incorrect when
e.g. the user has no search permission in a component of the path
prefix (=> EACCES), or if on component of the path prefix is a file (=>
ENOTDIR). This patch fixes that behavior.

25e850ebb1 Kernel: Remove krealloc()
This was only used by a single class (AK::ByteBuffer) in the kernel
and not in an OOM-safe way.

Now that ByteBuffer no longer uses it, there's no need for the kernel
heap to burden itself with supporting this.

966880eb45 AK: Don't use realloc() in AK::ByteBuffer
This class is the only reason we have to support krealloc() in the
kernel heap, something which adds a lot of complexity.

Let's move towards a simpler path and do malloc+memset in the
ByteBuffer code (where we know the sizes anyway.)

0718bd264c Kernel: Remove some no-longer-needed C library functions
Now that we no longer demangle symbols in the kernel, we don't need to
provide stuff like malloc(), memchr(), free(), etc to the demangler.

d38b4e4665 Kernel: Add kfree_sized(), kfree() with a known allocation size
C++14 gave us sized operator delete, but we haven't been taking
advantage of it. Let's get to a point where it can help us by
adding kfree_sized(void*, size_t).

47bfd366a8 LibWeb: Fix syntax for Table test
The parser fixes this by inserting the <tr> tags, but for this test it's
better to have perfect syntax - we're not testing the parser here.

3e46e8fea8 LibWeb: Fix HTMLTable Element attributes
`Element::tag_name` return an uppercase version of the tag name. However
the `Web::HTML::TagNames` values are all lowercase.

This change fixes that using `Element::local_name`, which returns a
lowercase value.

We can't use realpath() at that point because we've already called

paths with trailing slashes, empty paths, paths consisting of only
slashes and paths with ending "." and ".." segments.

If a user picks a file which can't be opened for some reason, we should
still return the value, so client applications can report the error
along with the chosen filepath.
