Although not explicitly requested, we are using K&R (or Kernel)
indentation for curly braces around functions in HACKING file and most
of the code.  Using grep -P, this patch add the syntax-check rule for
it (while skipping all the false positives with foreach constructs).

Per the documentation, is_selinux_enabled() returns -1 on error.
Account for this. Previously when -1 was being returned the condition
would still be true. I was noticing this because on my system that has
selinux disabled I was getting this in the libvirt.log every 5
seconds:

error : virIdentityGetSystem:173 : Unable to lookup SELinux process context: Invalid argument

With this patch applied, I no longer get these messages every 5
seconds. I am submitting this in case its deemed useful for inclusion.
Anyone have any comments on this change? This is a patch off current
master.

New functionalities:
- connectGetMaxVcpus - on bhyve hardcode this value to 16
- nodeGetFreeMemory - do not use physmem_get on FreeBSD, since
                      it might get wrong value on systems with
                      more than 100GB of RAM
- nodeGetCPUMap - wrapper only for mapping function, currently not
                  supported by FreeBSD
- nodeSet/GetMemoryParameters - wrapper only for future improvements,
                                currently not supported by FreeBSD

The virSocketAddrMask method did not initialize all fields
in the sockaddr_in6 struct. In paticular the 'sin6_scope_id'
field could contain random garbage, which would in turn
affect the result of any later virSocketAddrFormat calls.
This led to ip6tables rules in the FORWARD chain which
matched on random garbage sin6_scope_id. Fortunately these
were ACCEPT rules, so the impact was merely that desired
traffic was blocked, rather than undesired traffic allowed.

Valgrind reported leaking of maxCpus and arch strings from
virXPathString, as well as the leak of the machineMaxCpus array.

Don't use 'str' for the strings we don't want to free, to allow
freeing of 'str' in the cleanup label and free machineMaxCpus
in virCapsReset too.

Currently, we use pthread_sigmask(SIG_BLOCK, ...) prior to calling
poll(). This is okay, as we don't want poll() to be interrupted.
However, then - immediately as we fall out from the poll() - we try to
restore the original sigmask - again using SIG_BLOCK. But as the man
page says, SIG_BLOCK adds signals to the signal mask:

SIG_BLOCK
      The set of blocked signals is the union of the current set and the set argument.

Therefore, when restoring the original mask, we need to completely
overwrite the one we set earlier and hence we should be using:

SIG_SETMASK
      The set of blocked signals is set to the argument set.

Problem is, since 20745748 we do both, parse <alias/> elements from
XML files and call qemuAssignDeviceAliases(). While generating runtime
info for domain at runtime is just fine in the test, we can parse just
inactive XML and remove all <alias/>-es from the XML files.
