  Atsushi SAKAI fixing a ot more typo
Daniel

* qemud/qemud.c src/virsh.c: fixing some user facing strings
  problems pointed out by Francesco Tombolini should fix #436620
Daniel

* qemud/qemud.c (main): Don't call qemudCleanup on an
uninitialized pointer.

* qemud/qemud.c (qemudCleanup): Free the array as well as
the strings in it.

* qemud/qemud.c (main): Call qemudCleanup also upon failure.
Otherwise, an error return would skip it and induce leaks.

* qemud/qemud.c (remoteReadConfigFile): Be careful to free
"conf" after a successful virConfReadFile.

* qemud/Makefile.am: fix a broken line split
Daniel

* src/Makefile.am: Create a convenience library, libvirt_test.la,
and don't restrict access to *its* symbols.
* tests/Makefile.am (LDADDS): Add ../src/libvirt_test.la, so that
"configure --disable-shared" no longer provokes link errors.
(LIBVIRT): Remove definition.
(LDADDS): Remove use.
($(LIBVIRT)): Remove rule.
(LDADDS): Use the new convenience library instead.
(CLEANFILES): Define.
* docs/examples/index.py (dump_Makefile): Append $(COVERAGE_LDFLAGS),
to the LDADDS definition, to avoid link error with the combination of
--enable-test-coverage and --disable-shared.

* qemud/Makefile.am (SUFFIXES): Define to .x before implicit rule.

Avoid warnings like this:
file:nnn:format not a string literal and no format arguments

Also add "make syntax-check" rules to ensure no new uses sneak in.

There are many uses of write like this:

    if (write (fd, xml, towrite) != towrite)
        return -1;

The problem is that the syscall can succeed, yet write less than
the requested number of bytes, so the caller should retry
rather than simply failing.

This patch changes most of them to use util.c's safewrite wrapper,
which encapsulates the process.  Also, there were a few cases in
which the retry loop was open-coded, and I replaced those, too.

* Makefile.maint (sc_avoid_write): New rule, to avoid recurrence.
* .x-sc_avoid_write: New file.  Record two legitimate exemptions.
* qemud/qemud.c (sig_handler, qemudClientWriteBuf): Use safewrite, not write.
* src/conf.c (__virConfWriteFile): Likewise.
* src/qemu_conf.c (qemudSaveConfig, qemudSaveNetworkConfig): Likewise.
* src/qemu_driver.c (qemudWaitForMonitor, qemudStartVMDaemon)
(qemudVMData, PROC_IP_FORWARD): Likewise.
* proxy/libvirt_proxy.c: Include "util.h".
(proxyWriteClientSocket): Use safewrite.
* src/test.c (testDomainSave, testDomainCoreDump): Likewise.
* src/proxy_internal.c (virProxyWriteClientSocket): Likewise.
* src/virsh.c: Include "util-lib.h".
(vshOutputLogFile): Use safewrite.
* src/console.c: Include "util-lib.h".
(vshRunConsole): Use safewrite.

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.

* Makefile.cfg (local-checks-to-skip): Remove sc_no_have_config_h.
* qemud/mdns.c: Remove "#ifdef HAVE_CONFIG_H".
* Makefile.maint (sc_no_have_config_h): Tighten up regexp,
so that the above mention of "HAVE_CONFIG_H" doesn't match.
* .x-sc_no_have_config_h: New file, to exempt gnulib/ straggler.

* qemud/remote.c: fix a missing ')' introduced earlier
Daniel

Given code like: T *var = calloc (n, sizeof (T));
Convert to this: T *var = calloc (n, sizeof (*var));
This first-cut change adjusts all malloc, calloc, and
realloc statements.

The only binary differences are in remote_internal.c
(due to the bug fix) and in xmlrpc.c (due to factorization).
