This path can be dependent on the VM libdir, which contains its name

Need to convert the local function to virBuffer usage, so we
can use qemuBufferEscapeComma

This isn't sufficient on its own, since the VM name is used for things
like monitor paths, which we don't escape yet

Centralize the magic invocation for escaping commas on the qemu
command line, and document it a bit

QEMU_CAPS_DEVICE is always set nowadays, so drop code that depends
on not-DEVICE

When registering admin UNIX socket, a new service is created for it. This
service is incorrectly initialized to be readonly, which is later inherited by
all clients connected to the socket. In libvirt-admin's case there currently
isn't any use for the attribute anyway, but since the socket has root-only
access permissions, the least we can do is to make every admin client
connected to it report readonly as false.

When searching for the best CPU model for CPUID data we can easily
ignore models with non-matching vendor before spending time on CPUID
data to virCPUDef conversion.

Rather than returning a "char *" indicating perhaps some sized set of
characters that is NUL terminated, alter the function to return 0 or -1
for success/failure and add two parameters to handle returning the
buffer and it's size.

The function no longer encodes the returned secret, rather it returns
the unencoded secret forcing callers to make the necessary adjustments.

Alter the callers to handle the adjusted model.

They don't free the structure itself so they should be called *Clear

Add a new helper that sanitizes error semantics of base64_encode_alloc.

Call the internal driver callbacks rather than the public APIs to avoid
calling unnecessarily the error dispatching code and don't overwrite
the error messages provided by the APIs. They are good enough to
describe which secret is missing either by UUID or the usage (basically
name).

For a few cases where we handle secret information it's good to clear
the buffers containing sensitive data before freeing them.

Introduce VIR_DISPOSE, VIR_DISPOSE_N and VIR_DISPOSE_STRING that allow
simple clearing fo the buffers holding sensitive information on cleanup
paths.

When -cpu host is supported by a QEMU binary, a user can use
<cpu mode='host-passthrough'/> in domain XML even when libvirtd failed
to find a matching model for the host CPU. Let's make it obvious by
advertising <cpuselection/> guest capability whenever -cpu host is
supported.

This script will check output generated by virtestmock against a
white list. All non matching records found are printed out. So
far, the white list is rather sparse at the moment.
This test should be ran only after all other tests finished, and
should cleanup the temporary file before their execution. Because
I'm unable to reflect these requirements in Makefile.am
correctly, I've introduced new target 'check-access' under which
this test is available.

All the accesses to files outside our build or source directories
are now identified and appended into a file for later processing.
The location of the file that contains all the records can be
controlled via VIR_TEST_FILE_ACCESS env variable and defaults to
abs_builddir "/test_file_access.txt".

The script that will process the access file is to be added in
next commit.

There is some magic going on when it comes to stat() or lstat().
Basically, stat() can either be a regular function, an inline
function that calls __xstat(_STAT_VER, ...) or a macro that does
the same as the inline func. Don't ask why is that, just read the
documentation in sys/stat.h and make sure you have a bucket next
to you. Anyway, currently there will not be both stat and __xstat
symbols at the same time, as one of them gets overwritten to the
other one during compilation. But this is not true anymore once
we start chaining our mocking libraries. Therefore we need a
wrapper that calls desired function from glibc.
