cffafd90de Base: More helpful Desktop selection
If Serenity is ever used for more than a few days, the user will be more likely to
want to interact with their home directory than just be dropped at '/'.

Also, we have a Welcome program. Spotlight it!

And finally, there was a missing newline in the build script.

7ad31651bd Meta: Use a bash shebang for text-to-cpp-string.sh
Previously we had /bin/sh, which might be bash but is run in POSIX mode
on some systems, causing read -r to not work correctly and inserting
newlines when encountering literal "\n" in the source.

Fixes #5040.

86f50aa74e Shell: Make tests use PASS/FAIL instead of exit codes
There's no guarantee that the last executed command will have a zero
exit code, and so the shell exit code may or may not be zero, even if
all the tests pass.
Also changes the `test || echo fail && exit` to
`if not test { echo fail && exit }`, since that's nicer-looking.

1d621ab172 Kernel: Some futex improvements
This adds support for FUTEX_WAKE_OP, FUTEX_WAIT_BITSET, FUTEX_WAKE_BITSET,
FUTEX_REQUEUE, and FUTEX_CMP_REQUEUE, as well well as global and private
futex and absolute/relative timeouts against the appropriate clock. This
also changes the implementation so that kernel resources are only used when
a thread is blocked on a futex.

Global futexes are implemented as offsets in VMObjects, so that different
processes can share a futex against the same VMObject despite potentially
being mapped at different virtual addresses.

bf0719092f Kernel+Userland: Remove shared buffers (shbufs)
All users of this mechanism have been switched to anonymous files and
passing file descriptors with sendfd()/recvfd().

Shbufs got us where we are today, but it's time we say good-bye to them
and welcome a much more idiomatic replacement. :^)

9a688af4b1 LibCore+passwd+su+Base: Add /etc/shadow to hide hashes from users :^)
This patch moves the user account password hashes from /etc/passwd,
where they were world-readable, to /etc/shadow, where only root can
access them.

The Core::Account class is extended to support both authentication
against, and modification of /etc/shadow.

The default password for "anon" as of this commit is "foo" :^)

6df15aca7e Kernel/USB: Implement test transfer
We can now test a _very_ basic transaction via `do_debug_transfer()`.
This function merely attaches some TDs to the LSCTRL queue head
and points some input and output buffers. We then sense an interrupt
with USBSTS value of 1, meaning Interrupt On Completion
(of the transaction). At this point, the input buffer is filled with
some data.

f98ca35b83 Kernel: Improve ProcFS behavior in low memory conditions
When ProcFS could no longer allocate KBuffer objects to serve calls to
read, it would just return 0, indicating EOF. This then triggered
parsing errors because code assumed it read the file.

Because read isn't supposed to return ENOMEM, change ProcFS to populate
the file data upon file open or seek to the beginning. This also means
that calls to open can now return ENOMEM if needed. This allows the
caller to either be able to successfully open the file and read it, or
fail to open it in the first place.

3e815ad5b1 Loader.so+LibELF: Move most of Loader.so's logic into ELF::DynamicLinker
Loader.so now just performs the initial self relocations and static
LibC initialisation before handing over to ELF::DynamicLinker::linker_main
to handle the rest of the process.

As a trade-off, ELF::DynamicLinker needs to be explicitly excluded from
Lagom unless we really want to try writing a cross platform dynamic loader

54c66b8f7b Meta: Bump default RAM size to 512MB
Now that we commit memory, we need a lot more physical memory. Physical
memory requirements can be reduced again once we have memory swapping,
which allows the swap area/file to be counted against memory that can
be committed.

bc5d6992a4 Kernel: Memory purging improvements
This adds the ability for a Region to define volatile/nonvolatile
areas within mapped memory using madvise(). This also means that
memory purging takes into account all views of the PurgeableVMObject
and only purges memory that is not needed by all of them. When calling
madvise() to change an area to nonvolatile memory, return whether
memory from that area was purged. At that time also try to remap
all memory that is requested to be nonvolatile, and if insufficient
pages are available notify the caller of that fact.

91b65ec328 Build: Expose symbols SECTION_start and SECTION_size for embedded resources.
Resources embedded by the embed_resource() function will now also expose
a SECTION_start and SECTION_size symbol so the embedded resource can be found
by an application without having to parse its own ELF image which is not
something applications can currently do from userspace.

72b1998f0d Kernel: Introduce a new partitioning subsystem
The partitioning code was very outdated, and required a full refactor.
The new subsystem removes duplicated code and uses more AK containers.

The most important change is that all implementations of the
PartitionTable class conform to one interface, which made it possible
to remove unnecessary code in the EBRPartitionTable class.

Finding partitions is now done in the StorageManagement singleton,
instead of doing so in init.cpp.

Also, now we don't try to find partitions on demand - the kernel will
try to detect if a StorageDevice is partitioned, and if so, will check
what is the partition table, which could be MBR, GUID or EBR.
Then, it will create DiskPartitionMetadata object for each partition
that is available in the partition table. This object will be used
by the partition enumeration code to create a DiskPartition with the
correct minor number.
