78a63930cc Kernel+LibELF: Validate PT_LOAD and PT_TLS offsets before memcpy()'ing
Before this, you could make the kernel copy memory from anywhere by
setting up an ELF executable with a program header specifying file
offsets outside the file.

Since ELFImage didn't even know how large it was, we had no clue that
we were copying things from outside the ELF.

Fix this by adding a size field to ELFImage and validating program
header ranges before memcpy()'ing to them.

The ELF code is definitely going to need more validation and checking.

0f393148da Kernel: Separate out the symbol offsets in profile output
Instead of saying "main +39" and "main +57" etc, we now have a separate
field in /proc/profile for the offset-into-the-symbol.

49635e62fa LibELF: Move AK/ELF/ into Libraries/LibELF/
Let's arrange things like this instead. It didn't feel right for all of
the ELF handling code to live in AK.
