The "filename" is a bit of a misnomer, as it's only used during error
messages, and in most instances cases is actually set to "command
line".
Rename it to "config_source" to make it clear that it's not used to
actually open any files.
No functional changes.

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'

Provide a copy of the standard TOSTRING macro in libxlu_internal.h,
for the benefit of patches later in this series.
Also, move TOSTRING to libxl_internal.h from a .c file for the
benefit of future other callers in libxl proper.
(These cannot be combined because libxlu cannot include
libxl_internal.h and libxl should not include libxlu_internal.h.)

The characters - + . ( ) : are not legal in xl config files but are
valid Python and use of at least one of them is almost essential for
writing arbitrary Python in the config file.
So if we see one of these during lexing, note it, and then after the
parse is complete if it failed we print a special extra warning.
Currently this warning refers to the nonexistent wiki page
http://wiki.xen.org/xenwiki/PythonInXlConfig
which will have to be written (and/or given a better name) before the
actual 4.1 release.

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".
