76d31244c5 rpc: fix escaping of shell path for netcat binary
Consider having a nc binary in the path with a space in its name,
for example '/tmp/fo o/nc'

This results in libvirt running SSH with the following arg value

  "'if ''/tmp/fo o/nc'' -q 2>&1 | grep \"requires
    an argument\" >/dev/null 2>&1; then ARG=-q0;
    else ARG=;fi;''/tmp/fo o/nc'' $ARG -U
    /var/run/libvirt/libvirt-sock'"

The use of the single quote escaping was introduced by

  commit 6ac6238de3
  Author: Guido Günther <agx@sigxcpu.org>
  Date:   Thu Oct 13 21:49:01 2011 +0200

    Use virBufferEscapeShell in virNetSocketNewConnectSSH

    to escape the netcat command since it's passed to the shell. Adjust
    expected test case output accordingly.

While the intention of this change was good, the result is broken as it
is still underquoted.

On the SSH server side, SSH itself runs the command via the shell.
Our command is then invoking the shell again. Thus we see

$ virsh -c qemu+ssh://root@domokun/system?netcat=%2Ftmp%2Ffo%20o%2Fnc list
error: failed to connect to the hypervisor
error: End of file while reading data: sh: /tmp/fo: No such file or directory: Input/output error

With the second level of escaping added we can now successfully use a nc
binary with a space in the path.

The original test case added was misleading as it illustrated using a
binary path of 'nc -4' which is not a path, it is a command with a
separate argument, which is getting interpreted as a path.

1939bcd539 rpc: always pass "-T -e none" args to ssh
Way back in the past, the "no_tty=1" option was added for the remote
driver to disable local password prompting by disabling use of the local
tty:

  commit b32f429849
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Fri Sep 21 20:17:09 2007 +0000

    Added a no_tty param to remote URIs to stop SSH prompting for password

This was done by adding "-T -o BatchMode=yes -e none" args to ssh. This
achieved the desired results but is none the less semantically flawed
because it is mixing up config parameters for the local tty vs the
remote tty.

The "-T" arg stops allocation of a TTY on the remote host. This is good
for all libvirt SSH tunnels as we never require a TTY for our usage
model, so we should have just passed this unconditionally.

The "-e none" option disables the escape character for sessions with a
TTY. If we pass "-T" this is not required, but it also not harmful to
add it, so we should just pass it unconditionally too.

Only the "-o BatchMode=yes" option is related to disabling local
password prompts and thus needs control via the no_tty URI param.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

39015a6f3a tests: rewrite socket to do something sensible and reliable
The current socket test is rather crazy in that it sets up a server
listening for sockets and then runs a client connect call, relying on
the fact that the kernel will accept this despite the application
not having called accept() yet. It then closes the client socket and
calls accept() on the server. On Linux accept() will always see that
the client has gone and so skip the rest of the code. On FreeBSD,
however, the accept sometimes succeeds, causing us to then go into
code that attempts to read and write to the client which will fail
aborting the test. The accept() never succeeds on FreeBSD guests
with a single CPU, but as you add more CPUs, accept() becomes more and
more likely to succeed, giving a 100% failure rate for the test when
using 8 CPUs.

This completely rewrites the test so that it is avoids this designed in
race condition. We simply spawn a background thread to act as the
client, which will read a byte from the server and write it back again.
The main thread can now properly listen and accept the client in a
synchronous manner avoiding any races.

9b45c9f049 virnetsocket: Provide socket address format in a more standard form
Our socket address format is in a rather non-standard format and that is
because sasl library requires the IP address and service to be delimited by a
semicolon. The string form is a completely internal matter, however once the
admin interfaces to retrieve client identity information are merged, we should
return the socket address string in a common format, e.g. format defined by
URI rfc-3986, i.e. the IP address and service are delimited by a colon and
in case of an IPv6 address, square brackets are added:

Examples:
    127.0.0.1:1234
    [::1]:1234

This patch changes our default format to the one described above, while adding
separate methods to request the non-standard SASL format using semicolon as a
delimiter.

grep -e '\.[ch]$' -e '\.py$'

Found files were modified with this command:

-e 's_^\(.*\<return\)\s*(\([^()]*\))\s*\(;.*$\)_\1 \2\3_'

Then checked for nonsense.
