While configuring aggregate route prepare the hash table first,
then prepare the aggregated aspath value just like lcomm,
ecomm and standard community.

This commit fixes all of them except the bgp `recieved` issue due to
it being part of json output. That one will need to go through
a deprecation cycle.

The correct cast for these is (unsigned char), because "char" could be
signed and thus have some negative value. isalpha & co. expect an int
arg that is positive, i.e. 0-255. So we need to cast to (unsigned char)
when calling any of these.

Problems reported that if multiple peers have "remove-private-AS
replace-AS" with each other and all are using private asns, the as-path
gets hosed and continues to grow when a prefix is removed. This fix
disallows removing and replacing the private asn if it matches the
peer's ASN so that normal as-path loop prevention will operate correctly.

It doesn't make much sense for a hash function to modify its argument,
so const the hash input.
BGP does it in a couple places, those cast away the const. Not great but
not any worse than it was.

With this commit:
1) 'struct bgp_aggregate' is moved to bgp_route.h from bgp_route.c
2) Hashes to accommodate the as-path, communities, extended-communities and
large-communities attributes of all the routes aggregated by an
aggregate route is introduced in 'struct bgp_aggregate'.
3) Place-holders for the aggregate route's as-path, communities,
extended-communities and large-communities attributes are introduced in
'struct bgp_aggregate'.
4) The code to manage the as-path of the routes that are aggregatable under
a configured aggregate-address is introduced.
5) The code to compute the aggregate-route's as-path is introduced.

The ->hash_cmp and linked list ->cmp functions were sometimes
being used interchangeably and this really is not a good
thing. So let's modify the hash_cmp function pointer to return
a boolean and convert everything to use the new syntax.

There is no need to check for failure of a ALLOC call
as that any failure to do so will result in a assert
happening. So we can safely remove all of this code.

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

The creation of the json object for the aspath
is both memory intensive and expensive to
create. Only create the json object when
it is needed and stash it for further usage
at that point.

clang provides a notice about it that this p++ is useless,
because ++ would be done after the return.
From code review, I understand that p shall be incremented
for each token that is parsed from the buf. So let's keep
this intent.
Note that this commit is changing the behaviour of the source
code since from now p++ will be returned instead of p.
However, it does not hurt since the only consumer
just free() the aspath if it is parsed as as_token_unknown.
Let's be safe with a proper execution flow from now.
PS:
C reminders:
int f7(void) {
int j = 7;
return ++j; // return 8
}
int f8(void) {
int j = 7;
return j++; // return 7
}

If you have an AS_PATH with more entries than
what can be written into a single AS_SEGMENT_MAX
it needs to be broken up. The code that noticed
that the AS_PATH needs to be broken up was not
correctly calculating the size of the resulting
message. This patch addresses this issue.
This patch was built from an email that Andreas
sent to the dev alias for FRRouting.

1) Add hash names to all hash_create calls
2) Fix community_hash, ecommunity_hash and lcommunity_hash key
creation
3) Fix output of community and lcommunity iterators( why would
we want to see the memory location of the backet? ).

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.

Description:
We use valgrind memcheck quite a bit to spot leaks in
our work with bgpd. In order to eliminate false positives,
we added code in the exit path to release the remaining
allocated memory.
Bgpd startup log message now includes pid.
Some little tweaks by Paul Jakma <paul.jakma@hpe.com>:
* bgp_mplsvpn.c: (str2prefix_rd) do the cleanup in common code at the end
and goto it.
[DL: dropped several chunks from original commit which are obsolete by
now on this tree.]
lib/zebra.h has FILTER_X #define's. These do not belong there.
Put them in lib/filter.h where they belong.

On higher warning levels, compilers expect %p printf arguments to be
void *. Since format string / argument warnings can be useful
otherwise, let's get rid of this noise by sprinkling casts to void *
over printf calls.
