bf33a14081 AK: Mark MemMem header-only functions as inline rather than static 
Avoid including a per-translation unit copy of all these functions.

Also, drive-by two clang-tidy fixes for readability-qualified-auto and
readability-implicit-bool-conversion.

5d0f666f22 LibJS: Don't set a prototype property on async functions 
This is now as defined in the spec. However since we execute async
functions in bytecode by transforming it to a generator function it must
have a prototype for the GeneratorObject. We check whether it is an
async function and in that case use the hardcoded generator object
prototype. This also ensures that user code cannot override this
property thus preventing exposing internal implementation details.

f99af1bef0 Kernel: Make sure OpenFileDescription is kept alive while read() blocks 
It's not safe to store OpenFileDescription in a raw pointer when
blocking, since another thread may decide to close the corresponding
file descriptor.

768915bbcd LibGUI: Make clipboard bitmap parsing more robust 
In particular, malicious programs used to be able to set arbitrary
values as "format", which could cause UB (most likely a crash).

Furthermore, we do not transmit palette data, so an application sending
an indexed bitmap cannot possibly expect the other side to receive a
useful image. Therefore, we refuse to build a bitmap.

f22c0ffe0c LibGUI+Everywhere: Make sync requests to Clipboard server more obvious 2021-11-21 11:49:06 +00:00

06f140a025 LibGUI: Avoid access to Clipboard server, clipboard text is never empty 
The clipboard cannot reasonably contain the empty string. The clipboard
can be empty (i.e. cleared), sure, but that this check was about whether
the clipboard contained the empty string.

This cannot easily happen for two reasons:
- TextEditor GUI elements disable their copy actions when the selection
  is empty.
- Clipboard::set_data, through which all text-copying operates,
  implicitly forbids empty strings, because Process::sys$anon_create
  forbids empty anonymous files.
- Even if it were sent (e.g. by creating a non-empty anonymous file and
  sending it manually to the Clipboard server), it would not be
  received, because decode(Decoder&, Core::AnonymousBuffer&) goes
  through mmap() with a size of 0, which also is forbidden by the
  Kernel.

In other words, if the clipboard is never the empty text, therefore
checking this condition is pointless, and we can save a roundtrip to the
Clipboard server.
