This adds static markers and systemtap tapsets for:
* type creation
* object lifetimes (creation, ref, unref, dispose, finalize)
* signal creation and emission
Signal emissions and finalization marker have a corresponding
*_end (or *-end in dtrace) version that is when the corresponding
operation is finished.

This adds static markers for dtrace, which are also usable
by systemtap. Additionally it adds a tapset for systemtap
that makes it easier to use the static markers.
These are enabled by default.
This initial set of probes is rather limited:
* allocation and free using g_malloc & co
* allocation and free using g_slice
* gquark name tracking (useful for converting quarks to strings in probes)
Notes on naming:
Its traditional with dtrace to use probe names with dashes as
delimiter (slice-alloc). Since dashes are not usable in identifiers
the C code uses double underscores (slice__alloc) which is converted
to dashes in the UI. We follow this for the shared lowlevel probe
names.
Additionally dtrace supports putting a "provider" part in the probe
names which is essentially a namespacing thing. On systemtap this
field is currently ignored (but may be implemented in the future), but
this is not really a problem since in systemtap the probes are
specified by combining the solib file and the marker name, so there
can't really be name conflicts.
For the systemtap tapset highlevel probes we instead use names that
are systemtapish with single dashes as separators.

Rather make it branch to get the due sequence length for the resulting
character code, we can as well get the minimum code value in the initial
branching.
Fixup for commit 133f66538d which
duplicated the contents of most of the migration documentation by
splitting it out into separate files but keeping the original file
intact (with a rename).
This removes the duplicated content from the renamed file.
This checks for the .gschema.xml file in the srcdir and builddir and
runs the schema validation on which one it finds. This handles
non-srcdir builds in both cases: .gschema.xml is in the tarball and
.gschema.xml is generated.
FreeBSD's malloc() sometimes returns unaligned memory if you are
requesting small sizes. This can get GVariant into trouble. For
example, consider the type "mmi" containing the value "just nothing".
According to the type signature, the memory containing this should be
aligned to a boundary of 4 since it might contain an int. The
serialised size of this value is 1 byte, however, and when you ask
FreeBSD to allocate memory of that size, it knows you can't put an int
into it so it doesn't bother aligning it.
This patch modifies the GVariant serialiser to not assert the alignment
constraint in the case that the size of the serialised data is smaller
than its own alignment requirement.
The GVariant serialiser works well with non-8-aligned memory, but the
comparison serialiser in the test case depends on memory being
8-aligned. Use posix_memalign() to get the memory used by this
serialiser.
These allow applications to give meaningful names to their sources.
Source names can then be used for debugging and profiling, for
example with systemtap or gdb.

This allows the caller to specify the reply type that they are expecting
for this call. If the reply comes back with the wrong type, GDBus will
generate an appropriate error internally.
- add a GVariantType * argument to g_dbus_connection_call() and
_call_sync().
- move the internal API for computing message types from introspection
data to be based on GVariantType instead of strings. Update users
of this code.
- have GDBusProxy pass this calculated GVariantType into
g_dbus_connection_call(). Remove the checks done in GDBusProxy.
- Update other users of the code (test cases, gdbus-tool, GSettings
tool, etc). In some cases, remove redundant checks; in some other
cases, we are fixing bugs because no checking was done where it
should have been.
Closes bug #619391.
If the .gschema.xml file was generated as the result of an implicit make
rule then make would 'rm' it after creating the validity stamp. This
would cause 'make install' to fail.
Ryan pointed out on IRC that we didn't do anything here. Looking at
the code, it's painfully obvious that we should be returning an error
here since a comment already says that we've exhausted all possible
options.
