6901d92ec4 virnetsockettest: Increase coverage
Add test cases for quotes appearing in the netcat parameter,
for the default behavior of proxy=auto where virt-ssh-helper
is used if available, and for proxy=native.

85064aae64 util: Fix getting CPU frequency on Apple Silicon
The hw.cpufrequency sysctl, which we use to obtain the CPU
frequency on macOS, is not available when running on Apple
Silicon, and as a consequence we currently report an error
whenever such information is requested.

The virNodeInfo.mhz field, where the CPU frequency gets stored,
is documented as being zero when the information could not be
obtained, and we already do that for Linux on aarch64. Extend
this behavior to macOS on Apple Silicon.

d295c14258 virFileRewrite: Move error reporting into callback
When rewriting a file using virFileRewrite() and error occurs
while writing into a temporary file it's actually the callback
that can report the most accurate error. Move error reporting
into very few callback we have currently. Those callbacks are
trivial so the benefit of this change is not obvious, but this
will change shortly when slightly more complicated callback is
introduced.

04ed251850 virFileRewrite: Allow setting owner
Currently, due to the way virFileRewrite() works, the rewritten
file is owned by user and group that the daemon runs under. So
far, this is not a problem, because the function is used to write
XML files or secrets for persistent objects (domains, networks,
etc.) and we don't need other users to read/write those files.

But shortly, this function is going to be used for creating files
for QEMU domains. There we want the QEMU process (i.e. different
user) to read the file.

Therefore, introduce two new arguments: @uid and @gid that allow
setting desired owner of the file. Pass -1 to preserve current
behaviour (i.e. create the file owned by the user running the
daemon).

specific NVRAM with the one from template. But it is very likely
that the path to the template is not stored in the domain
definition, which in turn makes the copy function
(qemuPrepareNVRAM()) fail.

The solution is simple - when preparing domain, specifically when
deciding whether the path to the template should be autofilled,
ignore any existing NVRAM file.
