This allows other components to reference basic UEFI types. Now
different platforms can provide their own override for certain UEFI
protocols.
To keep good include structure, all public headers are put under
include/uefi.
This function was previously put in anon namespace, making it
unavailable for other source files to consume. Since we made this
function an API for consumption, move outside anon namespace so
that linkers can find it.
A large pile of changes to the PC platform and x86 architecture that
facilitate SMP support. Tested in both 64 and 32bit on qemu and real
hardware all the way back through i486.
For LK_DEBUGLEVEL > 1

size: max(alloc_struct_begin_size, free_heap_chunk_size)
But when freeing the chunk, allocated size is expected to be
greater than size of free_heap_chunk struct.
It contradicts its own code.
So add >= instead of > to maintain the integrity between
allocation and freeing of memory chunk.

GCC 14 is quite picky about warnings, probably more so than clang.
-Fix a bunch of printf warnings. Pointers should be printed with %p.
-Move some stuff into an anonymous namespace.
-Worked around GCC really not liking reinterpret_casting from one
function pointer type to another. Fiddled with it a bit and eventually
settled on casting the function pointer to const void * and passing it
through.
This change updates the `help` console command to list the available
commands alphabetically, but only when we're not panicking. This makes
`help`'s helping more helpful.
This loads all sections specified by PE header at the correct memory
location, and executes the entry point function. Only the
OutputString function of text output protocol is implemented,
so the only application we can run is hello world.

Thids adds a uefi_load <block dev name> command, which will
parse the PE header and do some basic validation checks.

It's just a test routine that's using floating point, but since nothing
in cmpctmalloc should be used in interrupt context, it should be okay to
mark this code as using float.
- Add the file operations APIs for VirtIO 9p devices, such as file
create/open/close/read/write/stat.
- After this commit, almost complete file operations for v9p file
sharing are supported. An intuitive example is that users can use
filesystem commands, such as `ls`, to examine the shared folder.
Example:
```
# Build the littlekernel with the current directory (the codebase) as
the shared v9p folder
$ scripts/do-qemuarm -f .
...
welcome to lk/MP
boot args 0x0 0x0 0x0 0x0
INIT: cpu 0, calling hook 0x8011fa81 (version) at level 0x3ffff,
flags 0x1
...
# Mount the default VirtIO 9p device `v9p0` as the 9p filesystem onto
# `/v9p` path
] fs mount /v9p 9p v9p0
# List the `/v9p` folder, and we can see the littlekernel codebase
] ls /v9p
