a331653dad Add pidfile argument to __virExec
virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.

79d9d2432f Add helper function virExecDaemonize
Wraps __virExec with the VIR_EXEC_DAEMON flag. Waits on the intermediate
process to ensure we don't end up with any zombies, and differentiates between
original process errors and intermediate process errors.

a178a4e7bf Move safewrite and saferead to a separate file.
We currently use safewrite from inside libvirt and don't want to publish
any such function name.  However, we do want to use it in applications
like virsh, libvirtd and libvirt_proxy that link with libvirt.  To that
end, this change moves that function definition (along with the nearly
identical saferead) into a new file, util-lib.c.  To avoid maintaining
separate copies of even such small functions, we simply include that new
file from util.c.  Then, the separate applications that need to use
safewrite simply compile and link with util-lib.c.

Of course, this does mean that each of those applications will
containing two copies of these functions.  However, the functions
are so small that it's not worth worrying about that.

* src/util.c (saferead, safewrite): Move function definitions to
util-lib.c and include that .c file.
* src/util-lib.c (saferead, safewrite): New file.  Functions from src/util.c
with slight change (s/int r =/ssize_t r =/) to reflect read/write return type.
* src/util-lib.h: Declare the two moved functions.
* src/util.h: Remove declarations.  Include src/util-lib.h.
* proxy/Makefile.am (libvirt_proxy_SOURCES): Add src/util-lib.c.
* qemud/Makefile.am (libvirtd_SOURCES): Likewise.
* src/Makefile.am (virsh_SOURCES): Add util-lib.c.  Remove some SP-before-TAB.

* src/internal.h: move xstrol() variants from here ...

* src/util.[ch]: ... to here and rename to virStrToLong()

* src/libvirt_sym.version: export __virStrToLong_i() for
virsh and qemud.

* src/nodeinfo.c, src/stats_linux.c, src/virsh.c,
  src/xend_internal.c, qemud/qemud.c: replace xstrtol()
calls with virStrToLong()

* src/nodeinfo.h: don't include internal.h, which was only
needed for xstrtol(), but instead include libvirt.h which
is suffificient for the declarations in the header.
