44342a0efe build: use re-entrant functions in virsh
Yesterday's commit 15d2c9f pointed out that virsh was still using
localtime(), which is not thread-safe, even though virsh is
definitely multi-threaded.  Even if we only ever triggered it from
one thread, it's better safe than sorry for maintenance purposes.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_nonreentrant):
Tighten the rule.
* tools/virsh.c (vshOutputLogFile): Avoid localtime.
(vshEditWriteToTempFile, vshEditReadBackFile, cmdCd, cmdPwd)
(vshCloseLogFile): Avoid strerror.
* tools/console.c (vshMakeStdinRaw): Likewise.
* tools/virsh-domain.c (vshGenFileName): Fix spacing in previous
patch.

Most likely this problem arose because of the patch I pushed
in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039.
Previously, gnulib required timeval's tv_sec to be
the same size as time_t.  But now, it requires only that
tv_sec be big enough to hold a time_t.

This patch was needed for Emacs.  Without the patch, gnulib
replaced struct timeval on OpenBSD, and this messed up
utimens.c, and Emacs wouldn't build.

Alternatively, gnulib could substitute its own struct timeval
for the system's, wrapping every struct timeval-using function
(gettimeofday, futimesat, futimes, lutimes, etc.  That'd be
more work, though.  And it would introduce some performance
issues with gettimeofday, which is supposed to be fast.

I've been trying to get away from using struct timeval,
and to use the higher-resolution struct timespec instead,
so messing with these obsolescent interfaces has been
lower priority for me.  But if someone wants to take the
more-ambitious approach that'd be fine, I expect.

For this particular case, though, how about if we avoid
the problem entirely?  libvirt doesn't need to use struct
timeval here at all.  It makes libvirt smaller and probably
faster, and it ports to OpenBSD without messing with gnulib.

67f83cd497 virsh: remove unneeded usage of vshConnectionUsability()
Now that vshCommandRun() checks for the connection automaticaly, remove
all of the redundant checks in the code.

vshConnectionUsability() no longer needs to be exported and this patch
marks it static.

4c10b3c7da virsh: declare more common functions
In preparation for splitting virsh-interface.c, I found these
functions need to be declared in virsh.h, as well as one that
belongs more properly in virsh-domain.h.  Also, since we
use the VSH_BY* flags in more than one function, I improved
how they are used.

* tools/virsh.h (vshNameSorter, vshCmdHasOption): Declare.
(VSH_BYID): Turn into enum.
(vshCommandOptDomainBy): Move...
* tools/virsh-domain.h): ...here.
* tools/virsh.c: (vshNameSorter): Export.
(cmd_has_option): Rename...
(vshCmdHasOption): ...and export.
(vshCommandOptDomainBy): Move...
* tools/virsh-domain.c (vshCommandOptDomainBy): ...here, adjust
signature, and check flags.
* tools/virsh-network.c (vshCommandOptNetworkBy): Update callers.
* tools/virsh-nwfilter.c (vshCommandOptNWFilterBy): Likewise.
* tools/virsh-secret.c (vshCommandOptSecret): Likewise.
* tools/virsh-domain-monitor.c (includes): Likewise.
* tools/virsh-host.c (includes): Likewise.

99ae57f841 virsh: split out virsh-domain-monitor.c
Another file worth compiling on its own instead of by .c inclusion.

* tools/virsh-domain-monitor.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh.h (vshGetDomainDescription): Move to correct
header.
* tools/virsh-domain-monitor.c: Use new header.
* tools/virsh.c: Likewise.
* tools/virsh-domain.c: Likewise.

6a48179803 Fix build of virsh on Win32 by moving SA_SIGINFO stub

to 0, but recent changes moved the usage out of virsh.c and
into virsh-domain.c

(DIFF_MSEC, CTRL_CLOSE_BRACKET): Delete.
(vshUsage, vshInit, vshDeinit, vshParseArgv): Remove prototype.

f4a7b87de0 virsh: split out virsh-domain.c
The virsh-domain.c file was pretty self-contained; the only
entry point was the table of command definitions.  The bulk
of this patch is making more functions in virsh.c reusable.
A later patch will clean up poor naming choices.

* tools/Makefile.am (virsh_SOURCES): Build virsh-domain.c.
* tools/virsh-domain.h: New file.
* tools/virsh.h (virshReportError, vshResetLibvirtError)
(vshAskReedit, vshStreamSink): Declare.
* tools/virsh.c: Switch from using .c to .h.
(virshReportError, vshResetLibvirtError, vshAskReedit)
(vshStreamSink, prettyCapacity): Export.
(vshCatchInt): Move...
* tools/virsh-domain.c: ...into sole user.  Use header.

8e8809e131 virsh: move vshWatchJob earlier
It's easier to order things in topological order than it is to
forward declare in one file for use only by one other file.

* tools/virsh.c (vshWatchJob, parseRateStr)
(vshDomainStateToString, vshDomainStateReasonToString)
(vshDomainControlStateToString, vshDomainVcpuStateToString): Drop
useless prototypes.
* tools/virsh-domain.c (vshWatchJob): Move earlier.

3df9626c40 virsh: Refactor error clearing on graceful fallback paths
Virsh uses an error handler to save errors from libvirt. On some code
paths it's needed to clear libvirt errors and continue on fallback code
paths without reporting failure.

This patch adds function vshResetLibvirtError() that clears error
returned by libvirt and updates all places where the old two-line method
was used.

dcfb7050c4 virsh: Check for existence of storage before undefining the domain
When undefining a domain and removing associated storage using "virsh
undefine --storage" the domain was at first undefined and after that the
storage removal proces was started. If the user specified an invalid
disk to remove, the error could not be corrected.

This patch moves enumeration and filtering of volumes that should be
removed before the domain is undefined, but the removal process is still
kept after the domain has been undefined.

73b89ed838 virsh: Split cmds of domain group from virsh.c
This splits commands to manage domain into virsh-domain.c,The helpers
not for common use are moved into them too. Standard copyright is added
for the new file.

* tools/virsh.c:
  - Remove commands for domain group, and one helper
    (vshDomainVcpuStateToString)
  - vshStreamSink is moved before commands's definition for it's
    also used by commands not of domain group, such as volUpload.

* tools/virsh-domain.c:
  - New file, commands for domain group and the one helper are
    moved into it.

* po/POTFILES.in:
  - Add virsh-domain.c

* cfg.mk:
  - Skip to check config.h including for virsh-domain.c
