I'm about to add a syntax check that enforces our documented
HACKING style of always using matching {} on if-else statements.

This patch focuses on all remaining problems, where there weren't
enough issues to warrant splitting it further.

The API is exposed under 'domcapabilities' command. Currently, with
the variety of drivers that libvirt supports, none of the command
arguments is obligatory, but all are optional instead.

In the 404bac14 the @tmp variable was introduced. It's purpose is to
avoid typecasting when parsing --pagesize argument. However, if the
argument is not presented, tmp may be used uninitialized resulting in
bogus virNodeGetFreePages() API call:

Commit 9e3efe53 broke the build under valgrind or clang, by writing
8 bytes through an allocation of 4 bytes.  It also risks multiplication
overflow when mallocing (that's a pervasive problem that needs an
audit in the rest of the code, but we might as well fix this one while
we are here), and had a typo.

My commit ac758012 removed the translation markers when
moving the field names into an array.

Rewrite the function to use an array instead of a struct,
translating the field names to int via an enum.

Implementation obtains CPU usage information using
kern.cp_time and kern.cp_times sysctl(8)s and reports
CPU utilization.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

The function is used to establish connection so it should be in the main
virsh file. This movement also enables further improvements done in next
patches.

Note that the "connect" command has moved from the host section of virsh to the
main section. It is now listed by 'virsh help virsh' instead of 'virsh help
host'.

Use the new helpers to determine mutually exclusive options and touch up
some parts to simplify the code.

After we switched to C99 initialization, I noticed there were many
places where the specification of .flags parameter differed.  After
going through many options and deciding whether to unify the
initialization to be '.flags = 0' or '.flags = VSH_OFLAG_NONE', I
realized both can be removed and it makes the code easier to go
through.

Linefeed is missed in the help of node-memory-tune.
This patch just adds '\n' to get a correct help message.

Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

The 3 options accept 0, and merely checking for non-zero values
would cause wrong results.

The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

We always expose individual bits from flags as separate options rather
than exposing a raw flags options. Since virNodeSuspendForDuration does
not currently support any flags, the only way of using this --flags
options that would not fail is "--flags 0", which is equivalent to
omitting the option. Thus it is highly unlikely anyone would actually be
using it and removing it should be safe.

Upstream kernel introduced new sysfs knob "merge_across_nodes" to
specify if pages from different numa nodes can be merged. When set
to 0, only pages which physically reside in the memory area of
same NUMA node can be merged. When set to 1, pages from all nodes
can be merged.

This patch supports the tuning by adding new param field
"shm_merge_across_nodes".
