Rather than running selected source files through the preprocessor and a
bunch of perl regex'ing to get the list of all DEFUNs, use the data
collected in frr.xref.
This not only eliminates issues we've been having with preprocessor
failures due to nonexistent header files, but is also much faster.
Where extract.pl would take 5s, this now finishes in 0.2s. And since
this is a non-parallelizable build step towards the end of the build
(dependent on a lot of other things being done already), the speedup is
actually noticeable.
Also files containing CLI no longer need to be listed in `vtysh_scan`
since the .xref data covers everything. `#ifndef VTYSH_EXTRACT_PL`
checks are equally obsolete.

FRR stores the route_tag in network byte order. Bug filed indicates
that the `show ip ospf route` command shows the correct value.
Every place route_tag is dumped in ospf_vty.c the ntohl function
is used first.

The `show ip ospf neighbor json` command was displaying
state:`Full\/DR`
Where state was both the role and whether or not the neigbhor
was converged. While from a OSPF perspective this is the state.
This state is a combination of two things.
This creates a problem in testing because we have no guarantee
that a particular ospf router will actually have a particular role
given how loaded our topotest systems are. So add a bit of json
output to display both the converged status as well as the
role this router is playing on this neighbor/interface.
The above becomes:
state:`Full\/DR`
converged:`Full`
role:`DR`
Tests can now be modified to look for `Full` and allow it to
continue. Most of the tests do not actually care if this
router is the DR or Backup.

When browsing or parsing OSPF LSA TLVs, we need to use the LSA length which is
part of the LSA header. This length, encoded in 16 bits, must be first
converted to host byte order with ntohs() function. However, Coverity Scan
considers that ntohs() function return TAINTED data. Thus, when the length is
used to control for() loop, Coverity Scan marks this part of the code as defect
with "Untrusted Loop Bound" due to the usage of Tainted variable. Similar
problems occur when browsing sub-TLV where length is extracted with ntohs().
To overcome this limitation, a size attribute has been added to the ospf_lsa
structure. The size is set when lsa->data buffer is allocated. In addition,
when an OSPF packet is received, the size of the payload is controlled before
contains is processed. For OSPF LSA, this allow a secure buffer allocation.
Thus, new size attribute contains the exact buffer allocation allowing a
strict control during TLV browsing.
This patch adds extra control to bound for() loop during TLV browsing to
avoid potential problem as suggested by Coverity Scan. Controls are based
on new size attribute of the ospf_lsa structure to avoid any ambiguity.

Replace sprintf with snprintf where straightforward to do so.
- sprintf's into local scope buffers of known size are replaced with the
equivalent snprintf call
- snprintf's into local scope buffers of known size that use the buffer
size expression now use sizeof(buffer)
- sprintf(buf + strlen(buf), ...) replaced with snprintf() into temp
buffer followed by strlcat
