30c4931d28 gendispatch: Cluster, don't capture if not needed
We were using parentheses for grouping admin|remote even though we didn't
need to capture what's in it.  That caused some changes to be greater
than needed and, to be honest, some confusion as well.  Let's use it as
it should be used.  It'll also make future changes more consistent.

d4218ca64f Change virNetDaemonGetServerNames to virNetDaemonGetServers
For now it does not matter which ones we return as the code is similarly
complex, however it will fit in with other constructs in the future,
mainly when we will be able to generate dispatch helpers.

a0dbed6160 admin: Do not work with virAdm on the server side
virAdm is prefix only used on the client side.  Or at least for now.  On
server, though, this corresponds to virNet structures (virAdmConnect is
virNetDaemon, virAdmServer should be virNetServer, in the future
virAdmClient will be resolved to virNetServerClient, and so on).

This will also make future work clearer and easier.

dad3b07814 server: Store server name in server object
At first I did not want to do this, but after trying to implement some
newer feaures in the admin API I realized we need that to make our lives
easier.  On the other hand they are not saved redundantly and the
virNetServer objects are still kept in a hash table.

b04e39ff86 admin: Check for flags properly
Function virAdmConnectListServers() forgot to check for flags at all,
virAdmConnectOpen() on the other hand checked them but did no dispatch
the error.  virCheckFlags() should be used only when there should be no
other thing done after erroring out and since they are used on different
places then just public API, they cannot dispatch errors.  So let's use
virCheckFlagsGoto instead.

1b13edb162 docs: generic.css: Indentation and spacing tweaks
- Add line-height:150% spacing for all text. This makes text lines far
  less cramped, and seems closer visually to what wikipedia uses.

- Remove bottom and top margin from lists: entries seemed needlessly
  spread out.

- Reduce sublist indentation a bit

- Add a bottom border after headings: IMO this greatly helps in break
  up the vertical flow of a big page of text. Doesn't look great on the
  front page, but helps a lot on dense pages like formatdomain

909be40181 docs: generic.css: font size tweaks
- change font-family to just 'sans-serif' rather than hardcode a few
  font families. this means we abide the user's browser font setting,
  and makes us consistent with other sites like en.wikipedia.org
- raise font-size to 90%. this is what en.wikipedia.org uses.

With these two tweaks, libvirt.org text renders the same as
en.wikipedia.org with fedora firefox out of the box config. Previously
the font on libvirt.org was very small and difficult to read.

fcd3fa385f qemu: support use of virtlogd with file based chardevs
Currently the file based character devices let QEMU write
directly to a file on disk. This allows a malicious QEMU
to inflict a denial of service by consuming all free space.

Switch QEMU to use a pipe to virtlogd, which will enforce
file rollover.
