Extend debug_create_symbol_lookup_context().

- debug_create_symbol_lookup_context() now takes an image ID
parameter that can optionally be used to restrict the symbols
it gathers to only those of the targeted image rather than the
entire team, allowing for significantly more lightweight usage
when the desired image is known. The previous behavior can still
be obtained if desired by passing -1 as said ID.

- Adjust callers.

ELF64 and x86_64 support in the debug kit.

Added debug_get_symbol(). It's not implemented particularly efficiently, though.

* Some refactoring: There are three ways to access the symbols of an image.
Formerly two were implemented in ImageFile (from file, via syscalls) and one
in SymbolLookup (via the debugger interface). Now there's a base class Image
and respective derived classes implementing those methods.
* Simplified SymbolIterator.
* Moved the classes into sub-namespace BPrivate::Debug.

Rather use the new _kern_read_kernel_image_symbols() syscall to use
kernel image symbol tables.

Also store the string table size for an image. This helps to improve the
symbol name len check.

* SymbolLookup: Implemented loading the symbol tables from the shared
object files. Thus static functions will be found, too.
* debug_lookup_symbol_address() and debug_next_image_symbol() no longer
need to read the symbol name via the debugger API, since the
respective SymbolLookup methods compute the length of the symbol name
that can safely be accessed locally, now.

Added work-around for a runtime loader problem after fork(). Its image
structures still have the parent IDs, so finding an image by ID would
fail in this case. We do now fall back to getting the image's text base
address and finding the image by address.

Added functionality for iterating through the symbols of a debugged
team's image to libdebug.

Added support for looking up symbols of other team to libdebug. The
debug_server uses this feature to print stack traces with symbols.
