3fe7ac0924 LibCrypto: Make a better ASN.1 parser
And use it to parse RSA keys.
As a bonus, this one shouldn't be reading out of bounds or messing with
the stack (as much) anymore.

363cc09091 Meta: Fix debug-flag detection
Detection broke when we moved from '#ifdef DEBUG_FOO dbgln()' to 'dbgln<DEBUG_FOO>()'.
This patch makes detection more general, which sadly runs into more false-positives.

No rotten code was found, hooray! :^)

2acbb811b1 LibCore: Added FileWatcher, a binding for the watch_file syscall
This wrapper abstracts the watch_file setup and file handling, and
allows using the watch_file events as part of the event loop via the
Core::Notifier class.

Also renames the existing DirectoryWatcher class to BlockingFileWatcher,
and adds support for the Modified mode in this class.

3f5532d43e LibWeb: Flesh out prepare_script and execute_script
This fills in a bunch of the FIXMEs that was in prepare_script.

execute_script is almost finished, it's just missing the module side.

As an aside, let's not assert when inserting a script element with
innerHTML.

fa18010477 HackStudio: Integate with C++ parser-based autocomplete
By default, C++ auto completion will still be performed by the
lexer-based logic.
However, the parser-based logic can be switched on via the menubar.

c96b6987c4 LibCpp: Add the beginning of a C++ parser
This parser will be used by the C++ langauge server to provide better
auto-complete (& maybe also other things in the future).

It is designed to be error tolerant, and keeps track of the position
spans of the AST nodes, which should be useful later for incremental
parsing.

1a3a0836c0 Everywhere: Use CMake to generate AK/Debug.h.
This was done with the help of several scripts, I dump them here to
easily find them later:

    awk '/#ifdef/ { print "#cmakedefine01 "$2 }' AK/Debug.h.in

    for debug_macro in $(awk '/#ifdef/ { print $2 }' AK/Debug.h.in)
    do
        find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/#ifdef '$debug_macro'/#if '$debug_macro'/' {} \;
    done

    # Remember to remove WRAPPER_GERNERATOR_DEBUG from the list.
    awk '/#cmake/ { print "set("$2" ON)" }' AK/Debug.h.in

These changes are arbitrarily divided into multiple commits to make it

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. :^)

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.

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.

bbedd320b5 Toolchain+LibC: Fix usage of crt files
We now configure the gcc spec files to use a different crt files for
static & PIE binaries.

This relieves us from the need to explicitly specify the desired crt0
file in cmake scripts.

e4ce485309 CMake: Decouple cmake utility functions from top-level CMakeLists.txt
Problem:
- These utility functions are only used in `AK`, but are being defined
  in the top-level. This clutters the top-level.

Solution:
- Move the utility functions to `Meta/CMake/utils.cmake` and include
  where needed.
- Also, move `all_the_debug_macros.cmake` into `Meta/CMake` directory
  to consolidate the location of `*.cmake` script files.
