682775fbb8 vsh: Make vshInitDebug static
There's no reason why debug initialization could not be made completely
hidden, just like readline initialization is. The point of the global
initializer vshInit is to make initialization of smaller features transparent
to the user/caller.

f59d51f518 vsh: Introduce vshInitReload
Commit a0b6a36f separated vshInitDebug from the original vshInit
(before virsh got split and vshInit became virshInit - commit 834c5720)
in order to be able to debug command line parsing.
After the parsing is finished, debugging is reinitialized to work properly.
There might as well be other features that require re-initialization as
the command line could specify parameters that override our defaults which
had been set prior to calling vshArgvParse.

57b8a38840 vsh: adjust vshInit signature and remove redundant error label
As part of the effort to stay consistent, change the vshInit signature
from returning int to returning bool. Moreover, remove the
unnecessary error label as there is no cleanup that would make use of
it.

0181975689 Remove static keyword from vshReadline when readline does not exist
This patch removes the static keyword from the vshReadline which was
introduced in commit 834c5720e4. With
readline the vshReadline function is not static but when compiling
without readline it was defined as static which caused compilation
error.

834c5720e4 tools: Introduce new client generic module vsh
In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.

Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.

Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.
