Nick Mathewson c4fe66e342 Socks5: handle truncated client requests correctly
Previously, our code would send back an error if the socks5 request
parser said anything but DONE.  But there are other non-error cases,
like TRUNCATED: we shouldn't send back errors for them.

This patch lowers the responsibility for setting the error message
into the parsing code, since the actual type of the error message
will depend on what problem was encountered.

Fixes bug 40190; bugfix on 0.3.5.1-alpha.

Nick Mathewson c116728209 Use __attribute__((fallthrough)) rather than magic GCC comments.
GCC added an implicit-fallthrough warning a while back, where it
would complain if you had a nontrivial "case:" block that didn't end
with break, return, or something like that.  Clang recently added
the same thing.

GCC, however, would let you annotate a fall-through as intended by
any of various magic "/* fall through */" comments.  Clang, however,
only seems to like "__attribute__((fallthrough))".  Fortunately, GCC
accepts that too.

A previous commit in this branch defined a FALLTHROUGH macro to do
the right thing if GNUC is defined; here we replace all of our "fall
through" comments with uses of that macro.

This is an automated commit, made with the following perl one-liner:

  #!/usr/bin/perl -i -p
  s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;

(In order to avoid conflicts, I'm applying this script separately to
each maint branch. This is the 0.4.3 version.)

liberat 4e4c4e72d7 Handle binary IPv6 addresses and bracketed strings in RESOLVE_PTR.
When a SOCKS5 client sends a RESOLVE_PTR request, it must include
either an IPv4 or IPv6 address.  In the past this was required to be a
binary address (address types 1 or 4), but since the refactoring of
SOCKS5 support in Tor 0.3.5.1-alpha, strings (address type 3) are also
allowed if they represent an IPv4 or IPv6 literal.

However, when a binary IPv6 address is provided,
parse_socks5_client_request converts it into a string enclosed in
brackets.  This doesn't match what string_is_valid_ipv6_address
expects, so this would fail with the error "socks5 received
RESOLVE_PTR command with hostname type. Rejecting."

By replacing string_is_valid_ipv4_address/string_is_valid_ipv6_address
with tor_addr_parse, we accept strings both with and without brackets.
This fixes the handling of binary addresses, and also improves
symmetry with CONNECT and RESOLVE requests.

Fixes bug 32315.

Nick Mathewson dddecee291 Initialize some locals in socks5 parsing code.
These confused GCC LTO, which thought they might be used
uninitialized.  I'm pretty sure that as long as 'res' indicates
success, they will always be set to something, but let's unconfuse
the compiler in any case.

Nick Mathewson 7ace8d5a61 Assert that some trunnel _new() functions return non-NULL
The trunnel functions are written under the assumption that their
allocators can fail, so GCC LTO thinks they might return NULL.  In
point of fact, they're using tor_malloc() and friends, which can't
fail, but GCC won't necessarily figure that out.

Fixes part of #27772.

Nick Mathewson 63b4ea22af Move literally everything out of src/or
This commit won't build yet -- it just puts everything in a slightly
more logical place.

The reasoning here is that "src/core" will hold the stuff that every (or
nearly every) tor instance will need in order to do onion routing.
Other features (including some necessary ones) will live in
"src/feature".  The "src/app" directory will hold the stuff needed
to have Tor be an application you can actually run.

This commit DOES NOT refactor the former contents of src/or into a
logical set of acyclic libraries, or change any code at all.  That
will have to come in the future.

We will continue to move things around and split them in the future,
but I hope this lays a reasonable groundwork for doing so.
