cdaa179eeb LibCore: Fix relative seeking in IODevice 
The recently introduced read buffer in IODevice broke relative seeking.
The amount of data in the buffer wouldn't get taken into account.

cb9cac4e40 LibIPC+IPCCompiler+AK: Make IPC value decoders return ErrorOr<void> 
This allows us to use TRY() in decoding helpers, leading to a nice
reduction in line count.

44ffe3e5bb LibCore: Allow System::pledge execpromises argument to be omitted 
It appears that we don't have almost no cases of a callers passing
exec promises when they call `pledge()`. To simplify the code a bit we
add a default parameter that will pass nullptr for us to `pledge()`.

fcc00c9a27 LibCore+cat: Switch Core::System::read/write to take a Span of bytes 
In the spirit of the Core::System name space having "modern" facades
for classically C functions / Kernel interfaces, it seems appropriate
that we should take Span's of data instead of raw pointer + length
arguments.

...and remove the Vector<String> variant since there are no remaining

b81ce827b6 LibCore: Add Core::Object::try_add<T>(...) 
This is a fallible version of add<T>(...) that returns ErrorOr<T>.
It can be used together with TRY() to handle allocation failures when
instantiating new Core::Objects.

7f780e43a6 LibCore: Allow moving, but not copying, DirIterator 
An explicit move constructor is required to null-out the moved-from
directory descriptor. Otherwise, we would call closedir() twice when
using ErrorOr<DirIterator>::release_value().

53e9b9758e LibCore: Add syscall wrapper for mmap() 
For convenience on SerenityOS, this also takes a custom alignment
request, and a memory region name. These are non-POSIX extensions.

58fb3ebf66 LibCore+AK: Move MappedFile from AK to LibCore 
MappedFile is strictly a userspace thing, so it doesn't belong in AK
(which is supposed to be user/kernel agnostic.)

21a5fb0fa2 LibCore+LibSystem: Move syscall wrappers from LibSystem to LibCore 
With this change, System::foo() becomes Core::System::foo().

Since LibCore builds on other systems than SerenityOS, we now have to
make sure that wrappers work with just a standard C library underneath.

7720644ae2 LibCore: Let ArgsParser::parse() accept Main::Arguments 
Instead of manually passing in `arguments.argc` and `arguments.argv`,
we can now just pass in the arguments directly.

216e21a1fa AK: Convert AK::Format formatting helpers to returning ErrorOr<void> 
This isn't a complete conversion to ErrorOr<void>, but a good chunk.
The end goal here is to propagate buffer allocation failures to the
caller, and allow the use of TRY() with formatting functions.

587f9af960 AK: Make JSON parser return ErrorOr<JsonValue> (instead of Optional) 
Also add slightly richer parse errors now that we can include a string
literal with returned errors.

This will allow us to use TRY() when working with JSON data.

53c8faaafc LibCore: Trim trailing whitespaces from ConfigFile values 
Previously, trailing whitespaces were not removed from values in
config files. This could cause errors with poorly formatted files.
This commit fixes this by trimming whitespaces from values in
ConfigFile::reparse().
