util: storagefile: Properly set transport type when parsing NBD strings
When parsing legacy NBD backing file strings such as

actually started to generate config of the backing store on the command

The GNULIB termios module ensures termios.h exists (but

already exclude usage of the functions that would exist

Libvirt's original atomic ops impls were largely copied
from GLib's code at the time. The only API difference
was that libvirt's virAtomicIntInc() would return a
value, but g_atomic_int_inc was void. We thus use
g_atomic_int_add(v, 1) instead, though this means
virAtomicIntInc() now returns the original value,
instead of the new value.
This rewrites libvirt's impl in terms of g_atomic_int*
as a short term conversion. The key motivation was to
quickly eliminate use of GNULIB's verify_expr() macro
which is not a direct match for G_STATIC_ASSERT_EXPR.
Long term all the callers should be updated to use
g_atomic_int* directly.

Windows sockets take a SOCKET HANDLE object instead of a
file descriptor. Wrap them in the same way that gnulib
does so that they use C runtime file descriptors.
While we could in theory use GSocket, it is hard to get
the exact same semantics libvirt has for its current
socket usage. Wrapping the Winsock2 APIs is thus the
easiest approach in the short term.
In changing the socke wrappers we need to re-implement
the nonblocking function too, since the GNULIB impl
expects to be used with the GNULIB sockets wrappers.

bhyve_parse_command.c: Don't jump onto non-existent label in CONSUME_ARG()
In v5.10.0-508-gfbf3f3d86a, the 'error' label was removed from
bhyveParseBhyveCommandLine(), however the CONSUME_ARG() macro
still uses it. Fix the macro to return an error instead.

vz: Don't try to jump on a non-existent label in prlsdkRemoveBootDevices()
Commit v5.10.0-522-g9000b2f298 was too aggressive and removed the
'error' label from prlsdkRemoveBootDevices() even though it's
used. Luckily, it's used only from one place and we have an
alternative for it that doesn't require the label.

qemu_firmware: Accept int in qemuFirmwareOSInterfaceTypeFromOsDefFirmware()
The point of this function is to translate virDomainOsDefFirmware
enum to qemuFirmwareOSInterface enum. However, with my commit v5.10.0-507-g8e1804f9f6 we are passing a variable type of
virDomainLoader enum. Make the function accept both enums and
make the enum members correspond to each other.
This fixes clang build.

remote_daemon: Initialize host boot time global variable
This is not strictly needed, but it makes sure we initialize the
@bootTime global variable. Thing is, in order to validate XATTRs
and prune those set in some previous runs of the host, a
timestamp is recorded in XATTRs. The host boot time was unique
enough so it was chosen as the timestamp value. And to avoid
querying and parsing /proc/uptime every time, the query function
does that only once and stores the boot time in a global
variable. However, the only time the query function is called is
in a child process that does lock files and changes seclabels. So
effectively, we are doing exactly what we wanted to prevent from
happening.
The fix is simple, call the virHostBootTimeInit() function which
sets the global variable.
