libvirt-common.h is generated into builddir/include/libvirt. apibuild.py
only operated on srcdir/inlcude/libvirt. With VPATH build
srcdir/docs/libvirt-libvirt-common.html would not get generated and make
RPM failed.
Since commit f5d9c5d00c moved the virTypedParam stuff into
libvirt-common we did not generate any docs for them and neither did we
populate them into libvirt-api.xml. This broke the sanity check in
libvirt python. Fix it by generating docs for libvirt-common.h too.
Some macros don't make sense to be documented at all. Add infrastructure
to the web/api generator and add VIR_DEPRECATED and VIR_EXPORT_VAR as
macros we should not document.
No online docs are build from it since it doesn't really fit into our
document structure and new page will need to be created for it, but this
is at least a heads-up commit for easier parsing in order to build some
documentation (or python bindings) later on.

If a macro has a string value, the @string attribute will contain the
value. Otherwise @string attribute will be missing.
For example, the following macro definition from libvirt-domain.h:
/**
* VIR_MIGRATE_PARAM_URI:
* ...
*/
# define VIR_MIGRATE_PARAM_URI "migrate_uri"
will result in
<macro name='VIR_MIGRATE_PARAM_URI' file='libvirt-domain' string='migrate_uri'>
<info><![CDATA[...]]></info>
</macro>

The apibuild.py script did not handle whitespace in preprocessor
macros, so it failed to detect constants declared with '# define'
instead of '#define'. Since we now correctly indent our public
header files, we have silently lost all constants from
libvirt-api.xml. This also caused us to not detect formatting
errors in constant docs
The API docs generators were broken by the header file
re-organization. Specifically
* html/libvirt-libvirt.html was empty (and should be deleted)
* Makefile.am didn't install html/libvirt-libvirt-*.html
* hvsupport.html was mostly empty
* sitemap.html.in didn't list the new html/*.html files
Create a new libvirt-host.h file to hold the public
API definitions for the virConnect type. This header
file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Create a new libvirt-domain.h file to hold the public
API definitions for the virDomain type. This header
file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Create a new libvirt-event.h file to hold the public
API definitions for the virEvent type. This header
file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Create a new libvirt-storage.h file to hold the public

file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Create a new libvirt-stream.h file to hold the public
API definitions for the virStream type. This header
file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Note the definition of virStreamPtr is not moved, since that
must be declared early for all other libvirt APIs to be able
to reference it.
Create a new libvirt-secret.h file to hold the public
API definitions for the virSecret type. This header
file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Create a new libvirt-nodedev.h file to hold the public

file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>
Create a new libvirt-interface.h file to hold the public

file is not self-contained, so applications will not directly
include it. They will continue to #include <libvirt/libvirt.h>

file is not self-contained, so applications will not directly

The virTypedParameterValidateSet method will need to be used
from several libvirt-*.c files so must be non-static

We publish libvirt-api.xml for others to use, and in fact, the
libvirt-python bindings use it to generate python constants that
correspond to our enum values. However, we had an off-by-one bug
that any enum that relied on C's rules for implicit initialization
of the first enum member to 0 got listed in the xml as having a
value of 1 (and all later members of the enum were equally
botched).
The fix is simple - since we add one to the previous value when
encountering an enum without an initializer, the previous value
must start at -1 so that the first enum member is assigned 0.
The python generator code has had the off-by-one ever since DV
first wrote it years ago, but most of our public enums were immune
because they had an explicit = 0 initializer. The only affected
enums are:
- virDomainEventGraphicsAddressType (such as
VIR_DOMAIN_EVENT_GRAPHICS_ADDRESS_IPV4), since commit 987e31e
(libvirt v0.8.0)
- virDomainCoreDumpFormat (such as VIR_DOMAIN_CORE_DUMP_FORMAT_RAW),
since commit 9fbaff0 (libvirt v1.2.3)
- virIPAddrType (such as VIR_IP_ADDR_TYPE_IPV4), since commit
03e0e79 (not yet released)
Thanks to Nehal J Wani for reporting the problem on IRC, and
for helping me zero in on the culprit function.

Our documentation generator is a bit messy, to say the least. For
instance, the description to return values of a function is
searched within C comment. Currently, all lines that start with
'returns' or 'Returns' are viewed as return value description.
However, there are some valid uses where the 'returns' word is in
the middle of a sentence describing function behavior not the
return value. And there are no places where 'returns' is used to
describe return values. For instance:
virDomainDetachDeviceFlags, virConnectNetworkEventRegisterAny and
virDomainGetDiskErrors. This leads to HTML documemtation being
generated incorrectly.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

Consistently use "is" or "is not" to compare variables to None,
because doing so is preferrable, as per PEP 8
(http://www.python.org/dev/peps/pep-0008/#programming-recommendations):
> Comparisons to singletons like None should always be done with is or
> is not, never the equality operators.
All APIs that take typed parameters are only using params address in
their entry point debug messages. With the new VIR_TYPED_PARAMS_DEBUG
macro, all functions can easily log all individual typed parameters
passed to them.
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.

Commit 6094ad7b (0.9.3 release) promoted several functions from
internal to public, but forgot to fix the documentation generator
to provide details about those functions.
For an example of what this fixes, look at:
file:///path/to/libvirt/docs/html/libvirt-libvirt.html#virEventAddHandle
before and after the patch.
* docs/apibuild.py (ignored_functions): Don't ignore functions
that were turned into official API.
* src/util/virevent.c: Fix comments to pass through parser.
When an exception happened inside the try clause in serialize_function,
a new exception was raised in the except clause subsequently:
