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.
C guarantees that static variables are zero-initialized. Some older
compilers (and also gcc -fno-zero-initialized-in-bss) create larger
binaries if you explicitly zero-initialize a static variable.
* tools/virsh-console.c (got_signal): Drop unused variable.
* tools/virsh-domain.c: Fix initialization.
* tools/virsh.c: Likewise.
* tools/virt-host-validate-common.c (virHostMsgWantEscape):
Likewise.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

vshRunConsole() uses virCondWait() which is a wrapper around
pthread_cond_wait(). On FreeBSD, pthread_cond_wait needs mutex to be
locked, otherwise it immediately fails with EPERM. On Linux, the
behaviour in this case is undefined.
So lock the mutex before calling virCondWait().
