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

The header inclusion in mtracebis.c should include zebra.h
and not config.h. There are other issues that need to
be worked through as well, but we can do this in the future.

config.h (or, transitively, zebra.h) must be the first include file
listed for autoconf things like _GNU_SOURCE and _POSIX_C_SOURCE to work
correctly.

Additional fix over d94023d85c (PR #2546)
Removed all pointer arithmetic used for the checks, while keeping same
coverage. I hope this removes the Coverity warning (If this don't fix it, I'll
make Coverity work with a fork and try there as many times as necessary)

Additional fix over 18e994a043 (PR #2457)
Previous correction was not enough for fixing the Coverity warning. Now we
ensure we don't overflow the buffer.

Adding to mtracebis querying with group address. Same change
to vtysh mtrace command. Support for querying (S,G) and (*,G)
state in mtrace router code. Further improvments to mtrace router
code with closer complience to IETF draft. More references in
comments to the draft. Man page has been updated accordingly.

The following types are nonstandard:
- u_char
- u_short
- u_int
- u_long
- u_int8_t
- u_int16_t
- u_int32_t
Replace them with the C99 standard types:
- uint8_t
- unsigned short
- unsigned int
- unsigned long
- uint8_t
- uint16_t
- uint32_t

This commit is the implementation of weak multicast traceroute.
It consists of IGMP module dealing with mtrace type IGMP messages
and client program mtrace/mtracebis for initiating mtrace queries.
