dad2f010b0 Do not skip hidden entries when looking for a stable path
The device names are unlikely to start with a dot.

44f5b3f869 Do not check the return value of closedir
The only possible error is EBADFD.
Since we only use the directory stream returned by opendir,
this should never happen.

cb049b9ad4 tests: utils: Fail XML file comparison if input file doesn't exist
In cases where we expect parse failure of the test input file the
testsuite can't differentiate if the parser failed when parsing or when
opening the file. Add a call to virFileExists and error out on missing
input files.

Missing output files are partially expected when regenerating test
output.

1eca5f6581 secret: Move virStorageSecretType and rename
Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.

This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

e808d3f227 storage: Remove redundant refreshPool check

6606ea96a1 qemu: make monitor command API available during async jobs
One can not issue monitor commands manually during async calls thru
designated API while this could be useful for testing/debugging purposes.
qemuDomainQemuMonitorCommand uses job of type QEMU_JOB_MODIFY and any async
call disable parallel execution of this type of job. The only state that is
changed is taint variable. AFAIU the only place we can mess is resetting
taint flag in qemuProcessStop routine under some async job. But this can not
happen thanx to both virDomainObjIsActive check in qemuDomainQemuMonitorCommand
and resetting active status in qemuProcessStop before taint flag.

  Change job type to QEMU_JOB_QUERY and thus make the API call available for
most of async jobs.

03ce132808 conf: Remove dead console compat formatting
This code was attempting to handle some implicit <console> XML
formatting for manually assembled DomainDef, since previously the
console<->serial compat copying was only done at XML parse time.

Nowadays it's done via virDomainDefPostParse ->
virDomainDefAddConsoleCompat, which all manual DomainDef builders
already call, so we can drop this workaround.

76d5871648 libxl: use serial device for console when targetType is serial
When domXML contains only <console type='pty'> and no corresponding
<serial>, the console is "stolen" [1] and used as the first <serial>
device. When this "stolen" console is accessed from the libxl driver
(in libxlConsoleCallback and libxlDomainOpenConsole), check if the
targetType is VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL, and use the
"stolen" device in def->serials[0] instead. Prior to this change,
creating a domain with input XML containing only a <console> device
and subsequently attempting to access its console with
'virsh console' would fail

error: internal error: character device <null> is not using a PTY

b1aa91e140 qemu: agent: Make setting of vcpus more robust
Documentation for the "guest-set-vcpus" command describes a proper
algorithm how to set vcpus. This patch makes the following changes:

- state of cpus that has not changed is not updated
- if the command was partially successful the command is re-tried with
  the rest of the arguments to get a proper error message
- code is more robust against malicious guest agent
- fix testsuite to the new semantics
