The `rate` keyword specifies the rate at which the outgoing traffic
will be limited to. The default if this keyword is not specified
is unlimited.
The `rate` keyword supports an optional replenishment interval
parameter for specifying the granularity of credit replenishment.
It determines the frequency at which the vif transmission credit
is replenished. The default interval is 50ms.
For example:
'rate=10Mb/s'
'rate=250KB/s'
'rate=1MB/s@20ms'

Config parsing functions do not properly belong in libxl. Move them into
libxlu so that others can use them or not as they see fit.
No functional changes. One side-effect was making public a private libxl
utility function which just set the elements of a structure from the function
arguments passed in.

This type is a but like a "boolean" but with a third state "default" (so really
I suppose it's a tristate).

Returns a cfg list as a libxl_string_list.
Use this to simplify the parsing of device model extra args.

Several places which were previsously indented using hard tabs are now
incorrectly indented. Fix them up.

I ran the following and committed the result. ^I is an actual hard tab
for i in $(grep -l --exclude=*_[ly].\[ch\] '^I' tools/libxl/*.[ch]) ; do
cat $i | expand | sponge $i
done
There are some actually wrong indentations too, I'll fix those up
manually.

Introduce new flex/regexp-based parser for disk configuration strings.
Callers will be updated in following patches.
The existing xm command line syntax for block-attach expects multiple
arguments containing different parameters for different parts of the
disk specification, so we supply a parser function which can take
multiple strings and scan them in sequence.

xl_cfg_get_list can cope with the option not being a list, but
it always reports a warning in this case. Introduce a parameter
to omit this warning if needed. Future code can then decide what
to do with this information.

The function init_dm_info() is initialising some strings from literals.
This is bad juju because when the destructor is called we cannot know if
the string literal was overridden with a strdup()'d value. Therefore
strdup values in the initialiser then introduce and use the function
libxlu_cfg_replace_string() which free's whatever is set before
strdupping the new value on top of it. The rule for the new call should
be clear due to const vs. non-const arguments - changing the behaviour
of libxlu_cfg_get_string() would cause more complexity than it saves.

We introduce a new format for saved domains. The new format, in
contrast to the old:
* Has a magic number which can distinguish it from other kinds of
file
* Is extensible
* Can contains the domain configuration file
On domain creation we remember the actual config file used (using the
toolstack data feature of libxl, just introduced), and by default save
it to the save file.
However, options are provided for the following:
* When saving a domain, supplying an alternative config file to
store in the savefile.
* When restoring a domain, supplying an alternative config file.
If a domain is restored with a different config file, it is the
responsibility of the xl user to ensure that the two configs are
"compatible". Changing the targets of virtual devices is supported;
changing other features of the domain is not recommended. Bad changes
may lead to undefined behaviour in the domain, and are in practice
likely to cause resume failures or crashes.
Old format save files generated by old versions of xl are not
supported.

This provides a replacement config file parser for "xl" based on bison
and flex.
Benefits:
* proper error reporting with line numbers
* parser can understand nearly all "xm" configuration files directly
(doesn't understand Python code but should do everything else)
* parser also understands the ;-infested "xl" style files
* removes the dependency on libconfig
* better checking for certain kinds of mistakes
* eliminates the strange "massage file and try again" code
This is intended to support all config files currently supported by
"xl" and almost all files supported by "xm". (NB that whether a
feature works depends on the implementation of that feature in
xl/libxl of course.)
This patch also introduces a new library "libxlutil" which is mainly
for the benefit of "xl". Users of libxl do not need to use libxlutil,
but they can do so if they want to parse "xl" files without being
"xl".
