77696510e2 tests: switch away from HAVE_SOCKETPAIR
Since the removal of gnulib, HAVE_SOCKETPAIR is no more defined, making
these two tests effectively skipped.

Use the same strategy used in other generic library bits, i.e. exclude
the socketpair usage on Windows.

Semi-related change in virnetdaemontest.c to make it build: since
virutil.h does not include unistd.h anymore, we need to include it.

c5ee737bc5 vmx: make 'fileName' optional for CD-ROMs
It seems like CD-ROMs may have no 'fileName' property specified in case
there is nothing configured as attachment for the drive. Hence, make
sure that virVMXParseDisk() do not consider it mandatory anymore,
considering it an empty block cdrom device. Sadly virVMXParseDisk() is
used also to parse disk and floppies, so make sure that a NULL fileName
is handled in cdrom- and floppy-related paths.

c9bd08ee35 conf: Don't generate clashing machine names for embed driver
So far, when using the qemu:///embed driver, management
applications can't chose whether they want to register their
domains in machined or not. While having that option is certainly
desired, it will require more work. What we can do meanwhile is
to generate names that include part of hash of the root
directory. This is to ensure that if two applications using
different roots but the same domain name (and ID) start the
domain no clashing name for machined is generated.

used now.

70d2758a9c qemuDomainSecretStorageSourcePrepare: Change aliases for disk secrets
Originally there was only the secret for authentication so we didn't use
any suffix to tell it apart. With the introduction of encryption we
added a 'luks' suffix for the encryption secrets. Since encryption is
really generic and authentication is not the only secret modify the
aliases for the secrets to better describe what they are used for.

This is possible as we store the disk secrets in the status XML thus
only new machines will use the new secrets.

46e16b553d tests: fix double unlock of monitor in hotplug test
The qemuMonitorTestNew() function returns with the monitor object
locked, and expects it to still be locked when qemuMonitorTestFree
is called.  The qemuhotplug test, however, explicitly unlocks the
monitor, but then forgets to lock it again. As a result the
qemuMonitorTestFree function is unlocking a mutex it doesn't own.

This bug has existed forever, but since we use normal POSIX mutexes
and don't check the return value of pthread_mutex_lock/unlock we
didn't see the error. It was harmless until the switch to the per
monitor event loop which requires the thread synchronization to
work reliably, whereupon it started crashing.

there was not better solution I guess.

In case we have the events the sync function is different. It allows us

But we need to do it only once. Until we get timeout on issued command

    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.
