if we have properly read in anything. So that a daemon
can make fallback plans.

Sometimes output would be mangled when filtering with include as a
result of the following bugs:
* Filters were applied per each call to vty_out() instead of buffering
until a line break and then applying
* Long output would sometimes be cut due to using the wrong buffer
pointer
Also remove the trailing \n as it should no longer be necessary to
ensure the vty prompt ends up on a new line.

This patch adds a CLI preprocessor function that activates when `|` is
found in the command. This is the start of adding support for some text
processing utilities intended for inline use. The first one implemented
here is `| include`, which provides grep-like filtering of command
output.

vty_frame() can be used to reduce the amount of output produced by "show
running-config" and "write ...". It buffers output in struct vty->frame
(1024 bytes) and outputs it when vty_out is called. If vty_out isn't
called, it can be removed with vty_endframe() later.

Multi-Instance OSPF configuration CLI would fail because
first client return error upon seeing qobj_index being 0.
With new marco generate new error code to return from each
instance (vtysh client) and if the command is intended for given
instance, its qobj_index would be nonzero and process the command
and push correct ospf context. Other instance would return the error.
On vtysh end, check all instance return an error log a message to a
file.
Testing Done:
Verfied various MI-OSPF configuration CLI with multi instances.

Instead of having an ?: expression embedded in every single caller of
vty_out, just expand \n to \r\n in the vty code if neccessary.
(Deprecation warnings will be enabled in the next commits which will do
the search-and-replace over the codebase.)

The xml2cli.pl script was useful years ago when the vty code was very
rudimentary. This is not the case anymore, so convert all ldpd CLI
commands to use DEFUNs directly and get rid of the XML interface.
The benefits are:
* Consistency with the other daemons;
* One less build dependency (the LibXML perl module);
* Easier to add new commands.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

As mentioned in previous commits, this prepares to replace the vty's
"void *index" context position with a safe qobj pointer. This will
allow concurrent configuration editing by multiple users, as soon as no
more code (library included) in the daemon uses vty->index anymore.

The VTY_GET_INTEGER_RANGE macro is failing on arm
with a warning->error issue where we are passing in
a unsigned MAXINT to this macro and it is complaining
that the comparison of (TMPL) > MAXINT is always going
to be false because of data structure size.
I've changed the tmp variable to a unsigned long long
which alleviates this issue.

This is intended to be used for either "exit on close", "fork on close"

these options to take depends on the context, the use case right now is

show update-groups summary was mislabeled. What it displays is not a summary
at all, but the detailed info about all update-groups. Furthermore, there
was no way to get detailed info about a specific subgroup.
This patch renames "show * update-groups summary" to "show * update-groups"
and adds an option to see the info specific to a subgroup only. It also
validates the subgroup-id.
show * update-groups summary will be added separately.
The VTY_GET_INTEGER_RANGE macro was being used also just to check the range
on a variable that wasn't used (for the "no" version of a VTY command), so I
split the macro into two. Also, since the variable is unsigned, if MIN is
zero, you get a warning about comparing an unsigned number against 0, giving
rise to slightly convoluted logic. Note that the previous two patches were
found by the -Wtype-limits and -Wunused-variables warnings. Without the
changes to these macros, these warnings are triggered erroneously, making it
harder to find the real problems.
