6d161bcc60 qemu: Rewrite chardev startup code to use qemuFDPass
Rewrite the parts which already pass FDs via fdset or directly to use
the new infrastructure.

Apart from simpler code this also adds the appropriate names to the fds
in the fdsets which will allow us to properly remove the fdsets won
hot-unplug of chardevs, which we didn't do for now and resulted in
leaking the FDs.

9aab7acfe0 qemuProcessPrepareHostBackendChardevFileHelper: Always use FD passing
Code paths which don't wish to use FD passing are supposed to not call
the function which sets up the chardev for FD passing.

This is ensured by calling it only in the host prepare step.

c9880b647b qemuxml2argvdata: Use proper arch and emulator for x86 real capability tests
Upcoming patches will modify how we populate the capability cache in
tests to be more saner. This also means that the emulator binary and
architecture used in the test files using real capabilities must match
what the real capabilities have.

d20ebdda28 qemu: Switch to -accel
We currently use -machine accel=XXX which is just a syntax sugar
for -accel XXX. The former doesn't allow specifying arguments for
accelerator, because all arguments passed to -machine are
treated as arguments of machine itself.

The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

d7c814f7f7 tests: convert name-escape to use real caps
For later QEMUs than 2.11 we do FD passing for character devices,
so lock the capabilites to this exact version.
