4eb3cf68b7 LibDebug: Avoid creating the String("serenity/") a bazillion times
We were creating and destroying this string twice for every LineInfo.
That's a lot of malloc() and free() during UE startup.

ef1b21004f Everywhere: Fix typos
Mostly in comments, but sprintf() now prints "August" instead of
"Auguest" so that's something.

fff581cd72 AK: Rename span() to bytes() when appropriate.
I originally defined the bytes() method for the String class, because it
made it obvious that it's a span of bytes instead of span of characters.

This commit makes this more consistent by defining a bytes() method when
the type of the span is known to be u8.

Additionaly, the cast operator to Bytes is overloaded for ByteBuffer and
such.

7eac9fe10e HackStudio: Support debugging library code
We can now step into library code in the debugger.

Since we now need the whole source code of our libraries
(and not just the headers), we clone the whole serenity git repo into
/usr/share/serenity.

This removes another call to ByteBuffer::wrap(const void*, size_t).

4a572df465 LibDebug: Put DWARF debug logging spam behind DEBUG_SPAM
With this logging enabled, it takes way too long to load debug info.

a4f23429aa LibDebug: Add support for enum value types
Additionally, we will parse and expose the types of variables
if they are complex, like Enums or Structs. Variables of an enum
type are special in that they do not store all the members of said
enum in their own VariableInfo like Structs do, rather, all of the
values are stored in the VariableInfo for the Enum.

We can now iterate the tree structure of the DIEs, access attribute
values and parse some very basic DWARF expressions.

8a886e0e96 LibDebug: Parse line number information from DWARF format
DWARF line number information, if generated, is stored  in the
.debug_line section of an object file.

The information is encoded as instructions for a VM that is defined in
the DWARF specification.
By executing these instructions, we can extract the encoded line number
information.
