f16ad06fb2 Introduce new APIs for spawning processes
This introduces a new set of APIs in src/util/command.h
to use for invoking commands. This is intended to replace
all current usage of virRun and virExec variants, with a
more flexible and less error prone API.

* src/util/command.c: New file.
* src/util/command.h: New header.
* src/Makefile.am (UTIL_SOURCES): Build it.
* src/libvirt_private.syms: Export symbols internally.
* tests/commandtest.c: New test.
* tests/Makefile.am (check_PROGRAMS): Run it.
* tests/commandhelper.c: Auxiliary program.
* tests/commanddata/test2.log - test15.log: New expected outputs.
* cfg.mk (useless_free_options): Add virCommandFree.
(msg_gen_function): Add virCommandError.
* po/POTFILES.in: New translation.
* .x-sc_avoid_write: Add exemption.
* tests/.gitignore: Ignore new built file.

d2af8ffcd8 maint: tighten strncmp syntax check
Using 'int ret = strcmp(a, b)' in a qsort function is a valid use of
str[n]cmp that should _not_ be turned to STREQ, but it was falling
foul of our specific syntax-check.  Meanwhile, gnulib's maint.mk
already has a tighter bound for strcmp, so we can copy that regex and
just check for strncmp, which results in fewer false positives that
require exceptions.

* cfg.mk (sc_prohibit_strcmp_and_strncmp): Rename...
(sc_prohibit_strncmp): ...to this, and tighten, to mirror
maint.mk's sc_prohibit_strcmp's better regex.
* Makefile.am (syntax_check_exceptions): Update exception rule.
* .x-sc_prohibit_strcmp_and_strncmp: Rename...
* .x-sc_prohibit_strncmp: ...and trim.

5f211d4bc5 build: rerun bootstrap if po/Makevars got nuked
There has been a frequent complaint of:

make[2]: Entering directory `/home/remote/eblake/libvirt/po'
make[2]: *** No rule to make target `/config.status', needed by `Makefile'.  Stop.

It happens after nuking and regenerating the po directory,
which is a common action after running anything like
'make dist' or 'make rpm' that dirties all the .po files.

Teach autogen.sh that it must regenerate po/Makevars to avoid
the missing variable declaration, and teach cfg.mk to recognize
that a nuked po directory is cause to rerun autogen.sh.

* cfg.mk (_update_required): Check for po/Makevars.
* autogen.sh (bootstrap): Run bootstrap if it got lost.
Diagnosed by Justin Clift.

337d201ef2 Qemu remote protocol.
Since we are adding a new "per-hypervisor" protocol, we
make it so that the qemu remote protocol uses a new
PROTOCOL and PROGRAM number.  This allows us to easily
distinguish it from the normal REMOTE protocol.

This necessitates changing the proc in remote_message_header
from a "remote_procedure" to an "unsigned", which should
be the same size (and thus preserve the on-wire protocol).

Changes since v1:
 - Fixed up a couple of script problems in remote_generate_stubs.pl
 - Switch an int flag to a bool in dispatch.c

Changes since v2:
 - None

Changes since v3:
 - Change unsigned proc to signed proc, to conform to spec

7cdf26637e maint: avoid spurious output if program not present
Some shells warn about missing programs before redirection;
the idiomatic way to silence them is to run the program check
inside a subshell, with the redirections outside the subshell.
But a subshell is only needed in places where it is reasonable
to expect the use of such a noisy shell in the first place.

* src/Makefile.am (remote_protocol-structs): Use subshell, for
FreeBSD 8.0 /bin/sh.
* cfg.mk (sc_preprocessor_indentation): Avoid subshell, since the
only users running cfg.mk can be assumed to have decent tools.

Noticed because virt-pki-validate was very inconsistent on

98caf6db76 Cleanup the msg_gen_function list in cfg.mk
Remove symbols that don't exist anymore (e.g. ERROR0) or aren't
message generating functions (e.g. VIR_FREE) or are now reported
as unmarked because the grep command is different, but that should
not be marked at all (e.g. DEBUG0).

Also don't restrict one of the grep lines in the
libvirt_unmarked_diagnostics rule to match exactly one space
between function name and opening parenthesis.

d002c250cd build: improve check for out-of-date .gnulib submodule
git reset --hard 96e5a2d4d5
./autogen.sh
make -s
git pull
make -s    <-- expecting auto-bootstrap here, doesn't happen

Use git diff to expose whether the submodule has untracked changes,
which are typical on an incremental pull if .gnulib was updated but
the user did not manually run 'git submodule update'.

After this patch is applied, I encountered a new problem when
following the reproducing pattern.  Basically, the change to .gnulib
between libvirt's commit 96e5a2d4 and this patch introduced a change
to sys_ioctl.in.h, but gnulib (intentionally) does not make the
replacement headers depend on Makefile changes.  Therefore, I ended up
with the generated replacement header being broken:
gnulib/lib/sys/ioctl.h complained about a use of @.  But that seems
like something that should be fixed upstream in gnulib's bootstrap
script (that is, when doing a gnulib update, all files created from
.in.h file should probably be deleted).  Without the benefit of that
proposed gnulib fix, I worked around the problem by manually removing
the stale gnulib/lib/sys/ioctl.h.

* autogen.sh (t): Also run bootstrap if the gnulib submodule needs
to be updated.
* cfg.mk (_autogen): Likewise.

A lot of syntax check rules have to be rewritten, but the
