abe038cfc0 Extend previous check to validate driver struct field names
Ensure that the driver struct field names match the public
API names. For an API virXXXX we must have a driver struct
field xXXXX. ie strip the leading 'vir' and lowercase any
leading uppercase letters.

1d69c6334b syntax-check: Don't include public headers in internal source
Directories python/tools/examples should include them in <> form,
though this patch allows "" form in these directories by excluding
them, a later patch will do the cleanup.

f9ce7dad60 Desert the FSF address in copyright
Per the FSF address could be changed from time to time, and GNU
recommends the following now: (http://www.gnu.org/licenses/gpl-howto.html)

  You should have received a copy of the GNU General Public License

This patch removes the explicit FSF address, and uses above instead
(of course, with inserting 'Lesser' before 'General').

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:

d91f3ef497 Santize the reporting of VIR_ERR_INVALID_ERROR
To ensure consistent error reporting of invalid arguments,
provide a number of predefined helper methods & macros.

 - An arg which must not be NULL:

   virCheckNonNullArgReturn(argname, retvalue)
   virCheckNonNullArgGoto(argname, label)

 - An arg which must be NULL

   virCheckNullArgGoto(argname, label)

 - An arg which must be positive (ie 1 or greater)

   virCheckPositiveArgGoto(argname, label)

 - An arg which must not be 0

   virCheckNonZeroArgGoto(argname, label)

 - An arg which must be zero

   virCheckZeroArgGoto(argname, label)

 - An arg which must not be negative (ie 0 or greater)

   virCheckNonNegativeArgGoto(argname, label)

3e2c3d8f6d build: use correct type for pid and similar types
No thanks to 64-bit windows, with 64-bit pid_t, we have to avoid
constructs like 'int pid'.  Our API in libvirt-qemu cannot be
changed without breaking ABI; but then again, libvirt-qemu can
only be used on systems that support UNIX sockets, which rules
out Windows (even if qemu could be compiled there) - so for all
points on the call chain that interact with this API decision,
we require a different variable name to make it clear that we
audited the use for safety.

Adding a syntax-check rule only solves half the battle; anywhere
that uses printf on a pid_t still needs to be converted, but that
will be a separate patch.

* cfg.mk (sc_correct_id_types): New syntax check.
* src/libvirt-qemu.c (virDomainQemuAttach): Document why we didn't
use pid_t for pid, and validate for overflow.

for syntax check.

06dbfa6d21 maint: print flags in hex during debug
Continuation of commit 313ac7fd, and enforce things with a syntax
check.

Technically, virNetServerClientCalculateHandleMode is not printing
a mode_t, but rather a collection of VIR_EVENT_HANDLE_* bits;
however, these bits are < 8, so there is no different in the
output, and that was the easiest way to silence the new syntax check.

* cfg.mk (sc_flags_debug): New syntax check.
(exclude_file_name_regexp--sc_flags_debug): Add exemptions.
* src/fdstream.c (virFDStreamOpenFileInternal): Print flags in
hex, mode_t in octal.

639f841346 Define a QEMU specific API to attach to a running QEMU process
Introduce a new API in libvirt-qemu.so

 virDomainPtr virDomainQemuAttach(virConnectPtr domain,
                                  unsigned long long pid,
                                  unsigned int flags);

This allows libvirtd to attach to an existing, externally
launched QEMU process. This is useful for QEMU developers who
prefer to launch QEMU themselves for debugging/devel reasons,
but still want the benefit of libvirt based tools like
virt-top, virt-viewer, etc

* include/libvirt/libvirt-qemu.h: Define virDomainQemuAttach
* src/driver.h, src/libvirt-qemu.c, src/libvirt_qemu.syms:
  Driver glue for virDomainQemuAttach

994e7567b6 maint: kill all remaining uses of old DEBUG macro
Done mechanically with:
$ git grep -l '\bDEBUG0\? *(' | xargs -L1 sed -i 's/\bDEBUG0\? *(/VIR_&/'

followed by manual deletion of qemudDebug in daemon/libvirtd.c, along
with a single 'make syntax-check' fallout in the same file, and the
actual deletion in src/util/logging.h.

* src/util/logging.h (DEBUG, DEBUG0): Delete.
* daemon/libvirtd.h (qemudDebug): Likewise.
* global: Change remaining clients over to VIR_DEBUG counterpart.

21adf03c2d Qemu Monitor API entry point.
Add the library entry point for the new virDomainQemuMonitorCommand()
entry point.  Because this is not part of the "normal" libvirt API,
it gets its own header file, library file, and will eventually
get its own over-the-wire protocol later in the series.

Changes since v1:
 - Go back to using the virDriver table for qemuDomainMonitorCommand, due to
   linking issues
 - Added versioning information to the libvirt-qemu.so

Changes since v2:
 - None

Changes since v3:
 - Add LGPL header to libvirt-qemu.c
 - Make virLibConnError and virLibDomainError macros instead of function calls

Changes since v4:
 - Move exported symbols to libvirt_qemu.syms
