util: add API for reading password from the console
the fact that "bufptr" pointer may point to either heap or stack
allocated data was overlooked. As a result, when the strdup was
removed, we ended up returning a pointer to the local stack to
the caller. When the caller referenced this stack pointer they
got out garbage which fairly quickly resulted in a crash.
We need to copy the stack buffer into heap memory in the username
case.

This deletes all trace of gnulib from libvirt. We still
have the keycodemapdb submodule to deal with. The simple
solution taken was to update it when running autogen.sh.
Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
about, given how infrequently keycodemapdb changes.

This was a straight conversion, manually going line-by-line to

Prepare for new backup APIs by describing the XML that will represent
a backup. The XML resembles snapshots and checkpoints in being able
to select actions for a set of disks, but has other differences. It
can support both push model (the hypervisor does the backup directly
into the destination file) and pull model (the hypervisor exposes an
access port for a third party to grab what is necessary). Add
testsuite coverage for some minimal uses of the XML.
The <disk> element within <domainbackup> tries to model the same
elements as a <disk> under <domain>, but sharing the RNG grammar
proved to be hairy. That is in part because while <domain> use
<source> to describe a host resource in use by the guest, a backup job
is using a host resource that is not visible to the guest: a push
backup action is instead describing a <target> (which ultimately could
be a remote network resource, but for simplicity the RNG just
validates a local file for now), and a pull backup action is instead
describing a temporary local file <scratch> (which probably should not
be a remote resource). A future refactoring may thus introduce some
way to parameterize RNG to accept <disk type='FOO'>...</disk> so that
the name of the subelement can be <source> for domain, or <target> or
<scratch> as needed for backups. Future patches may improve this area
of code.

For some architectures and setups, device removal can take
longer than the default 5 seconds. This results in commands
such as 'virsh setvcpus' to fire timeout messages even if
the operation were successful in the guest, confusing the
user.
This patch sets a new 10 seconds unplug timeout for PPC64
guests. All other archs will keep the default 5 seconds
timeout.
Instead of putting 'if PPC64' conditionals inside qemu_hotplug.c
to set the new timeout value, a new function called
qemuDomainGetUnplugTimeout was added. The timeout value is then
retrieved when needed, by passing the correspondent DomainDef
object. This approach allows for different guest architectures
to have distint unplug timeout intervals, regardless of the
host architecture. This design also makes it easier to
modify/enhance the unplug timeout logic in the future
(allow for special timeouts for TCG domains, for example).
A new mock file was created to work with qemuhotplugtest.c,
given that the test timeout is significantly shorter than
the actual timeout value in qemu_hotplug.c.
The now unused 'qemuDomainRemoveDeviceWaitTime' global can't
be simply erased from qemu_hotplug.c though. Next patch will
remove it properly.

gmem: clarify that g_malloc always uses the system allocator
Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.
This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.
This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.
Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.

bundle is used for plugins that are loaded with dlopen/dlsym/dlclose.
And there's no way to preload a bundle into an application. dynamic
linker (dyld) will reject it when finds it in DYLD_INSERT_LIBRARIES.
Unfortunately, a bundle is built if -module flag is provided to libtool.

Add a new file checkpoint_conf.c that performs the translation to and
from new XML describing a checkpoint. The code shares a common base
class with snapshots, since a checkpoint similarly represents the
domain state at a moment in time. Add some basic testing of round trip
XML handling through the new code.
Of note - this code intentionally differs from snapshots in that XML
schema validation is unconditional, rather than based on a public API
flag. We have many existing interfaces that still need to add a flag
for opt-in schema validation, but those interfaces have existing
clients that may not have been producing strictly-compliant XML, or we
may still uncover bugs where our RNG grammar is inconsistent with our
code (where omitting the opt-in flag allows existing apps to keep
working while waiting for an RNG patch). But since checkpoints are
brand-new, it's easier to ensure the code matches the schema by always
using the schema. If needed, a later patch could extend the API and
add a flag to turn on to request schema validation, rather than having
it forced (possibly just the validation of the <domain> sub-element
during REDEFINE) - but if a user encounters XML that looks like it
should be good but fails to validate with our RNG schema, they would
either have to upgrade to a new libvirt that adds the new flag, or
upgrade to a new libvirt that fixes the RNG schema, which implies
adding such a flag won't help much.
Also, the redefine flag requires the <domain> sub-element to be
present, rather than catering to historical back-compat to older
versions.

Prepare for new checkpoint APIs by describing the XML that will

virDomainSnapshotPtr. See the docs for more details.
Add testsuite coverage for some minimal uses of the XML (bare minimum,
the sample from html, and a full dumpxml, and some counter-examples
that should fail schema validation). Although use of the REDEFINE flag
will require the <domain> subelement to be present, it is easier for
most of the tests to provide counterpart output produced with the
NO_DOMAIN flag (particularly since synthesizing a valid <domain>
during testing is not trivial).

If a management application wants to use firmware auto selection
feature it can't currently know if the libvirtd it's talking to

This commit then adds 'firmware' enum to <os/> element in
<domainCapabilities/> XML like this:
<enum name='firmware'>
<value>bios</value>
<value>efi</value>

Quite a few of the tests have a need to mock the stat() / lstat()
functions and they are taking somewhat different & inconsistent
approaches none of which are actually fully correct. This is shown
by fact that 'make check' fails on 32-bit hosts. Investigation
revealed that the code was calling into the native C library impl,
not getting intercepted by our mocks.
The POSIX stat() function might resolve to any number of different
symbols in the C library.
The may be an additional stat64() function exposed by the headers
too.
On 64-bit hosts the stat & stat64 functions are identical, always
refering to the 64-bit ABI.
On 32-bit hosts they refer to the 32-bit & 64-bit ABIs respectively.
Libvirt uses _FILE_OFFSET_BITS=64 on 32-bit hosts, which causes the
C library to transparently rewrite stat() calls to be stat64() calls.
Libvirt will never see the 32-bit ABI from the traditional stat()
call. We cannot assume this rewriting is done using a macro. It might
be, but on GLibC it is done with a magic __asm__ statement to apply
the rewrite at link time instead of at preprocessing.
In GLibC there may be two additional functions exposed by the headers,
__xstat() and __xstat64(). When these exist, stat() and stat64() are
transparently rewritten to call __xstat() and __xstat64() respectively.
The former symbols will not actally exist in the library at all, only
the header. The leading "__" indicates the symbols are a private impl
detail of the C library that applications should not care about.
Unfortunately, because we are trying to mock replace the C library,
we need to know about this internal impl detail.
With all this in mind the list of functions we have to mock will depend
on several factors
- If _FILE_OFFSET_BITS is set, then we are on a 32-bit host, and we
only need to mock stat64 and __xstat64. The other stat / __xstat
functions exist, but we'll never call them so they can be ignored
for mocking.
- If _FILE_OFFSET_BITS is not set, then we are on a 64-bit host and
we should mock stat, stat64, __xstat & __xstat64. Either may be
called by app code.
- If __xstat & __xstat64 exist, then stat & stat64 will not exist
as symbols in the library, so the latter should not be mocked.
The same all applies to lstat()
These rules are complex enough that we don't want to duplicate them
across every mock file, so this centralizes all the logic in a helper
file virmockstathelper.c that should be #included when needed. The
code merely need to provide a filename rewriting callback called
virMockStatRedirect(). Optionally VIR_MOCK_STAT_HOOK can be defined
as a macro if further processing is needed inline.

Had this been in place earlier, I would have avoided the bugs in
commit 0baf6945 and 55c2ab3e. Writing the test required me to extend
the power of virsh - creating enough snapshots to cause fanout
requires enough input in a single session that adding comments and
markers makes it easier to check that output is correct. It's still a
bit odd that with test:///default, reverting to a snapshot changes the
domain from running to paused (possibly a bug in how the test driver
copied from the qemu driver) - but the important part is that the test
is reproducible, and any future tweaks we make to snapshot code have
less chance of breaking successful command sequences.
