When processing bulk messages we need more space to handle more
mroutes. In this case we are doubling the stream size from
16k -> 32k, which should roughly double the number of mroutes
we can handle in one go.
Additionally. If we cannot parse the passed message into
the stream to pass up to pimd then gracefully stop processing

This one also needed a bit of shuffling around, but MTYPE_RE is the only
one left used across file boundaries now.

Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

The mlag_rd_buf_offset function was only ever being set to 0
in the mlag_read function and only written in that function.
There is no need for this global variable.

The normal pattern of writing the type/length at the beginning
of the packet was not being quite followed. Modify the mlag
code to respect the proper way of doing things and get rid
of a stream_new and copy.

Need to list #include'd header files in Makefile to make sure it builds
correctly.
Fixes: #6576

This patch does two things:
1) Ensure the decoding of stream data between pim <-> zebra is properly
decoded and we don't read beyond the end of the stream.
2) In zebra when we are freeing memory alloced ensure that we
actually have memory to delete before we do so.

Older versions of protobuf-c do not support version 3 of the
protocol. Add a check into the system to see if we have
version 3 available and if so, compile it in.

If you compile FRR with no j factor zebra_mlag.c fails to
build because the vtysh extraction methodology runs first
before the protobuf compiler runs and that compilation does
not have the proper dependancy chain built for the inclusions
that zebra_mlag.c had. Moving the DEF* code into a zebra_mlag_vty.c
which can be included in the vtysh extraction code and has
no mlag.proto dependancies makes the compilation work better.
