While being great semantic patching tool, coccinelle fails to
understand some of macros we use (including those provided by
glib). What they have in common is use of __attribute__ under the
hood. We store a list of such macros in a file. But in there,
g_auto() macro is not defined properly. Indeed, g_auto(type)
declares a local variable of given type, for instance from
cocci's POV:
g_auto(virBuffer) buf = VIR_BUFFER_INITIALIZER;
virBuffer buf = VIR_BUFFER_INITIALIZER;
are both the same declaration. Fix declaration of g_auto() stub.

In order to auto-generate more of the language binding code, it is
desirable to know what libvirt version an API was introduced in.
We can extract this information from the .syms files and expose
it in the API description
eg instead of
<function name='virNodeNumOfDevices' file='libvirt-nodedev'
module='libvirt-nodedev'>
we now have
<function name='virNodeNumOfDevices' file='libvirt-nodedev'
module='libvirt-nodedev' version='0.5.0'>
This will benefit this proposal:

The currrent generated API contains *** pointer types with bogus
whitespace in the middle:
<arg name='keys' type='char ** *' info='pointer to a variable to store authorized keys'/>
because the tokenizer only tries to merge 2 distinct '*' together.
This refactors the code to merge an arbitrary number, resulting
in
<arg name='keys' type='char ***' info='pointer to a variable to store authorized keys'/>

Add a cross reference of the enum value name with the string
representation. This allows a quick cross-reference of the values
without having to open the header and implementation files separately.
To achieve this the checker code at first obtains a list of the
flags and cross-references them when checking the grouping in
syntax-check, thus we are guaranteed to stay in sync.

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

This script works under two specific conditions. For each opened file,
search for all functions that has ACL calls and store them, and see
if there is a vir*DriverPtr struct declared in it. For each implementation
found, check if there is an ACL verification inside it, and error out if
none was found. The script also supports the concept of stub, where another
function takes the responsibility for the ACL call instead of the
original API.
Unfortunately this is not enough to cover the new scenario we have now,
with domain_driver.c containing helper functions that execute the ACL
calls. The script does not store state between files because, until now,
it wasn't needed to - APIs and stubs and vir*DriverPtr declarations were
always in the same file. Also, the script will not check for ACL in functions
that does not belong to a vir*DriverPtr interface. What we have now in
domain_driver.c breaks both assumptions: the functions are in a different
file, and there is no vir*DriverPtr being implemented in the file that
uses these functions.
This patch changes check-aclrules.py to accomodate this scenario. The helpers
that have ACL checks are stored beforehand in aclFuncHelpers, allowing other
files to use them to recognize a stub situation. In case the current file
being analyzed is domain_driver.c itself, we'll do a manual check using
aclFuncHelpers to verify that these functions indeed have ACL checks.

page.xsl was adding '<div id="content">' wrapper for the content picked
up from the <body> element from the original input file. Optionally
class="$DOCNAME" was added for some documents taken from <body>.
Since docs generated from RST by docutils have a '<div class='document'
id='$DOCNAME>' we actually don't need an extra wrapper for them.
Additionally if we standardize on one of them we can use the same styles
for both. I've picked the latter because it makes more sense to use the
document name as 'id'.
This patch:
1) Modifies the XSL trasformation to add the wrapper only if it's not
present.
2) Modifies the XSL transformation to use 'id' for document name and
class='document' for the wrapper element.
3) Changes docs.html/index.html/hvsupport.html to use 'id' instead of
'class' for document name.
4) Modifies the main stylesheet to keep styling the elements properly

There was one attempt a year ago done by me to drop HAL [1] but it was
never resolved. There was another time when Dan suggested to drop HAL
driver [2] but it was decided to keep it around in case device
assignment will be implemented for FreeBSD and the fact that
virt-manager uses node device driver [3].
I checked git history and code and it doesn't look like bhyve supports
device assignment so from that POV it should not block removing HAL.
The argument about virt-manager is not strong as well because libvirt
installed from FreeBSD packages doesn't have HAL support so it will not
affect these users as well [4].
The only users affected by this change would be the ones compiling
libvirt from GIT on FreeBSD.
I looked into alternatives and there is libudev-devd package on FreeBSD
but unfortunately it doesn't work as it doesn't list any devices when
used with libvirt. It provides libudev APIs using devd.
I also looked into devd directly and it provides some APIs but there are
no APIs for device monitoring and events so that would have to be
somehow done by libvirt.
Main motivation for dropping HAL support is to replace libdbus with GLib
dbus implementation and it cannot be done with HAL driver present in
libvirt because HAL APIs heavily depends on symbols provided by libdbus.

When a list is freed, we iterate through all the items, invoking the
free function for each; the actual free function called for each element
is the function of the actual type of each element, and thus the @_next
pointer in the element struct has the same type as the element itself.
Currently, the free function gets the parent of the current element
type, and invoke its free function to continue freeing the list.
However, in case the hierarchy of the classes has more than 1 level
(i.e. Class <- SubClass <- SubSubClass), the invoked free function is
only the parent class' one, and not the actual base class of the
hierarchy.
To fix that, change the generator to get the base class of a class, and
invoking that instead. Also, avoid to set the @_next back, as it is not
needed.

We need to modify check-file-access.py to be usable as wrapper for

meson test --setup access
which will run all tests using check-file-access.py as a wrapper.
With autotools all file access are written into single file for all
tests and compared once the whole test suite is done.
With Meson we will compare the file access after every single test
because it is used as wrapper now. That requires writing the file
access into separate files for every single test as they are executed
in parallel.
Since the wrapper is used for all tests in Meson including tests outside
of tests directory we have to check for presence of the output file.
We should also cleanup after ourselves.
