Sergio Durigan Junior c7ab0aef11 Implement IPv6 support for GDB/gdbserver 
This patch implements IPv6 support for both GDB and gdbserver.  Based
on my research, it is the fourth attempt to do that since 2006.  Since
I used ideas from all of the previous patches, I also added their
authors's names on the ChangeLogs as a way to recognize their
efforts.  For reference sake, you can find the previous attempts at:

  https://sourceware.org/ml/gdb-patches/2006-09/msg00192.html

  https://sourceware.org/ml/gdb-patches/2014-02/msg00248.html

  https://sourceware.org/ml/gdb-patches/2016-02/msg00226.html

The basic idea behind the patch is to start using the new
'getaddrinfo'/'getnameinfo' calls, which are responsible for
translating names and addresses in a protocol-independent way.  This
means that if we ever have a new version of the IP protocol, we won't
need to change the code again (or, at least, won't have to change the
majority of the code).

The function 'getaddrinfo' returns a linked list of possible addresses
to connect to.  Dealing with multiple addresses proved to be a hard
task with the current TCP auto-retry mechanism implemented on
ser-tcp:net_open.  For example, when gdbserver listened only on an
IPv4 socket:

  $ ./gdbserver --once 127.0.0.1:1234 ./a.out

and GDB was instructed to try to connect to both IPv6 and IPv4
sockets:

  $ ./gdb -ex 'target extended-remote localhost:1234' ./a.out

the user would notice a somewhat big delay before GDB was able to
connect to the IPv4 socket.  This happened because GDB was trying to
connect to the IPv6 socket first, and had to wait until the connection
timed out before it tried to connect to the IPv4 socket.

For that reason, I had to rewrite the main loop and implement a new
method for handling multiple connections.  After some discussion,
Pedro and I agreed on the following algorithm:

  1) For each entry returned by 'getaddrinfo', we try to open a socket
  and connect to it.

  2.a) If we have a successful 'connect', we just use that connection.

  2.b) If we don't have a successfull 'connect', but if we've got a
  ECONNREFUSED (meaning the the connection was refused), we keep track
  of this fact by using a flag.

  2.c) If we don't have a successfull 'connect', but if we've got a
  EINPROGRESS (meaning that the connection is in progress), we perform
  a 'select' call on the socket until we have a result (either a
  successful connection, or an error on the socket).

  3) If tcp_auto_retry is true, and we haven't gotten a successful
  connection, and at least one of our attempts failed with
  ECONNREFUSED, then we wait a little bit (i.e., call
  'wait_for_connect'), check to see if there was a
  timeout/interruption (in which case we bail out), and then go back
  to (1).

After multiple tests, I was able to connect without delay on the
scenario described above, and was also able to connect in all other
types of scenarios.

I also implemented some hostname parsing functions (along with their
corresponding unit tests) which are used to help GDB and gdbserver to
parse hostname strings provided by the user.  These new functions are
living inside common/netstuff.[ch].  I've had to do that since IPv6
introduces a new URL scheme, which defines that square brackets can be
used to enclose the host part and differentiate it from the
port (e.g., "[::1]:1234" means "host ::1, port 1234").  I spent some
time thinking about a reasonable way to interpret what the user wants,
and I came up with the following:

  - If the user has provided a prefix that doesn't specify the protocol
    version (i.e., "tcp:" or "udp:"), or if the user has not provided
    any prefix, don't make any assumptions (i.e., assume AF_UNSPEC when
    dealing with 'getaddrinfo') *unless* the host starts with "[" (in
    which case, assume it's an IPv6 host).

  - If the user has provided a prefix that does specify the protocol
    version (i.e., "tcp4:", "tcp6:", "udp4:" or "udp6:"), then respect
    that.

This method doesn't follow strictly what RFC 2732 proposes (that
literal IPv6 addresses should be provided enclosed in "[" and "]")
because IPv6 addresses still can be provided without square brackets
in our case, but since we have prefixes to specify protocol versions I
think this is not an issue.

Another thing worth mentioning is the new 'GDB_TEST_SOCKETHOST'
testcase parameter, which makes it possible to specify the
hostname (without the port) to be used when testing GDB and
gdbserver.  For example, to run IPv6 tests:

  $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp6:[::1]'

Or, to run IPv4 tests:

  $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp4:127.0.0.1'

This required a few changes on the gdbserver-base.exp, and also a
minimal adjustment on gdb.server/run-without-local-binary.exp.

Finally, I've implemented a new testcase,
gdb.server/server-connect.exp, which is supposed to run on the native
host and perform various "smoke tests" using different connection
methods.

This patch has been regression-tested on BuildBot and locally, and
also built using a x86_64-w64-mingw32 GCC, and no problems were found.
