4e650259f9 virsh: Treat any command name starting with # as comment
As the previous commit mentioned, argv mode (such as when you feed
virsh via stdin with <<\EOF instead of via a single shell argument)
didn't permit comments. Do this by treating any command name token
that starts with # as a comment which silently eats all remaining
arguments to the next newline or semicolon.

Note that batch mode recognizes unquoted # at the start of any word as
a command as part of the tokenizer, while this patch only treats # at
the start of the command word as a comment (any other # remaining by
the time vshCommandParse() is processing things was already quoted
during the tokenzier, and as such was probably intended as the actual
argument to the command word earlier in the line).

Now I can do something like:

$ virsh -c test:///default <<EOF
  # setup
  snapshot-create-as test s1
  snapshot-create-as test s2
  # check
  snapshot-list test --name
EOF

834f64ca47 virsh: Parse # comments in batch mode
Continuing from what I did in commit 4817dec0, now I want to write a
sequence that is self-documenting.  So I need comments :)

Now I can do something like:

$ virsh -c test:///default '
  # setup
  snapshot-create-as test s1
  snapshot-create-as test s2
  # check
  snapshot-list test --name
'

Note that this does NOT accept comments in argv mode, another patch
will tackle that.

(If I'm not careful, I might turn virsh into a full-fledged 'sh'
replacement? Here's hoping I don't go that far...)

5817dec014 virsh: Elide backslash-newline in batch mode
The previous patch made it possible to split multiple commands by
adding newline, but not to split a long single command. The sequence
backslash-newline was being used as if it were a quoted newline
character, rather than completely elided the way the shell does.

Again, add more tests, although this time it seems more like I am
suffering from a leaning-toothpick syndrome with all the \.

fe1b683fd0 virsh: Treat \n like ; in batch mode
I wanted to do a demonstration with virsh batch mode, which
takes multiple commands all packed into a single argument:

$ virsh -c test:///default 'echo a; echo b;'
a
b

but that produced a really long line, so I tried to make it
more legible:

$ virsh -c test:///default '
   echo a;
   echo b;
'
error: unknown command: '
'

Let's be more like the shell, and treat unquoted newline as a
command separator just as we do for semicolon.  In fact, with
that, I can even now mix styles:

$ virsh -c test:///default '
   echo a; echo b
   echo c
'
a
b
c

f5f32bcd1b admin: Fix default uri config option name s/admin_uri_default/uri_default
The original name 'admin_uri_default' was introduced to our code by commit
dbecb87f. However, at that time we already had a separate config file for
admin library but the commit mentioned above didn't properly adjust the
config's option name. The result is that when we're loading the config, we
check a non-existent config option (there's not much to do with the URIs
anyway, since we only allow local connection). Additionally, virt-admin's man
page documents, that the default URI can be altered by setting
admin_uri_default option. So the fix proposed by this patch leaves the
libvirt-admin.conf as is and adjusts the naming in the code as well as in the
virt-admin's man page.

4e930bb8be virt-admin.pod: Remove a statement about remote access to the daemon
There's been a forgotten fragment (copy-paste error probably) in the
virt-admin's man page referring the reader to our web page on how to construct
URIs in case of remote access, which sort of implies that we support it which
we don't at the moment, so better remove that.

de7703917d virt-admin: Introduce srv-clients-list command
Wire-up the public client listing API. Along with this change, a private time
simple conversion method to interpret client's timestamp obtained from server
has been added as well. Format used to for time output is as follows:
YYYY-mm-DD HH:MM:SS+ZZZZ.

Although libvirt exposes methods time-related methods through virtime.h
internally, it utilizes millisecond precision which we don't need in this case,
especially when connection timestamps use precision to seconds only.
This is just a convenience int to string conversion method.

To reflect the new API, man page has been adjusted accordingly.
