6cbd72f54f AK: Remove bitrotted Traits::dump() mechanism 
This was only used by HashTable::dump() which I used when doing the
first HashTable implementation. Removing this allows us to also remove
most includes of <AK/kstdio.h>.

084e67f267 Meta: Integrate Shellcheck into Travis 
lint-shell-scripts searches over the repository looking for shell
scripts. On those found, shellcheck is run against them. If any linting
fails print those warnings and exit with a non-zero exit code.

Run this script automatically in Travis.

fe668db999 Meta: Fix shellcheck warnings in various scripts 
Warnings fixed:
 * SC2086: Double quote to prevent globbing and word splitting.
 * SC2006: Use $(...) notation instead of legacy backticked `...`
 * SC2039: In POSIX sh, echo flags are undefined
 * SC2209: Use var=$(command) to assign output (or quote to assign string)
 * SC2164: Use 'cd ... || exit' or 'cd ... || return' in case cd fails
 * SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
 * SC2034: i appears unused. Verify use (or export if used externally)
 * SC2046: Quote this to prevent word splitting.
 * SC2236: Use -z instead of ! -n.

There are still a lot of warnings in Kernel/run about:
 - SC2086: Double quote to prevent globbing and word splitting.

However, splitting on space is intentional in this case, and not trivial to
change. Therefore ignore the warning for now - but we should fix this in
the future.

6c752c15a2 WebServer: Implement a very basic HTTP server :^) 
This server listens on port 8000 and serves HTML files from /www.
It's very simple and quite naive, but I think we can start here and
build our way to something pretty neat.

Work towards #792.

271bc4b2f2 Net: When routing to loopback, use the loopback adapter's MAC address 
Otherwise the routing decision gets interpreted as "host unreachable."

d8a30e2ad2 Net: Give the LoopbackAdapter a MAC address 
Since the routing code currently interprets an all-zero MAC address as
an invalid next hop, let's give the loopback adapter an address.

fc85d17322 TelnetServer: Protect the Client object during drain_socket()

defer deletion of the Client object until we're done with the socket.

228a1e9099 IPv4: Basic implementation of TCP socket shutdown 
We can now participate in the TCP connection closing handshake. :^)
This implementation is definitely not complete and needs to handle a
bunch of other cases. But it's a huge improvement over not being able
to close connections at all.

Note that we hold on to pending-close sockets indefinitely, until they
are moved into the Closed state. This should also have a timeout but
that's still a FIXME. :^)

Fixes #428.

8325662186 more: Read keystrokes from stdout instead of trying to re-open it 
If we're running more on a TTY that we don't have filesystem access to,
we can't rely on open(ttyname(STDOUT_FILENO)). Since all the stdio fd's
are opened read/write anyway, we can just read from stdout, even if it
feels a bit weird. :^)

48f13f2a81 IPv4: Split IPv4Socket::recvfrom() into packet/byte buffered functions

of buffering the data.

00d8ec3ead Kernel: The inode fault handler should grab the VMObject lock earlier 
It doesn't look healthy to create raw references into an array before
a temporary unlock. In fact, that temporary unlock looks generally
unhealthy, but it's a different problem.

unmapping instead of clearing individual fields.

8731682d0e Kernel: Simplify FS::create_directory() a little bit 
None of the clients of this function actually used the returned Inode,
so it can simply return a KResult instead.
