Commit 605df8d44 zebra: Use zebra dplane for RTM link and addr broke loading of
kernel routes at startup for configurations without netlink.
It rearranged the startup sequence in zebra_ns_enable() to pass via
zebra_ns_startup_continue(), triggered through zebra_dplane_startup_stage()
calls. However, it neglected to make these calls in the non-netlink code path.
As a result zebra failed to load kernel routes at startup on platforms such
as FreeBSD.
Insert these calls so we run through all of the expected startup stages.

The Solaris code has gone through a deprecation cycle. No-one
has said anything to us and worse of all we don't have any test
systems running Solaris to know if we are making changes that
are breaking on Solaris. Remove it from the system so
we can clean up a bit.

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.

This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.
The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.
bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use. This is bad practice and would break when the
memtype are made static.

Convert the rest of zebra over to use a Namespae and VRF.

The API messages are used by zebra to exchange the interfaces, addresses,
routes and router-id information with its clients. To distinguish which
VRF the information belongs to, a new field "VRF ID" is added in the
message header. And hence the message version is increased to 3.
* The new field "VRF ID" in the message header:
Length (2 bytes)
Marker (1 byte)
Version (1 byte)
VRF ID (2 bytes, newly added)
Command (2 bytes)
- Client side:
- zclient_create_header() adds the VRF ID in the message header.
- zclient_read() extracts and validates the VRF ID from the header,
and passes the VRF ID to the callback functions registered to
the API messages.
- All relative functions are appended with a new parameter "vrf_id",
including all the callback functions.
- "vrf_id" is also added to "struct zapi_ipv4" and "struct zapi_ipv6".
Clients need to correctly set the VRF ID when using the API
functions zapi_ipv4_route() and zapi_ipv6_route().
- Till now all messages sent from a client have the default VRF ID
"0" in the header.
- The HELLO message is special, which is used as the heart-beat of
a client, and has no relation with VRF. The VRF ID in the HELLO
message header will always be 0 and ignored by zebra.
- Zebra side:
- zserv_create_header() adds the VRF ID in the message header.
- zebra_client_read() extracts and validates the VRF ID from the
header, and passes the VRF ID to the functions which process
the received messages.
- All relative functions are appended with a new parameter "vrf_id".
* Suppress the messages in a VRF which a client does not care:
Some clients may not care about the information in the VRF X, and
zebra should not send the messages in the VRF X to those clients.
Extra flags are used to indicate which VRF is registered by a client,
and a new message ZEBRA_VRF_UNREGISTER is introduced to let a client
can unregister a VRF when it does not need any information in that
VRF.
A client sends any message other than ZEBRA_VRF_UNREGISTER in a VRF
will automatically register to that VRF.
- lib/vrf:
A new utility "VRF bit-map" is provided to manage the flags for
VRFs, one bit per VRF ID.
- Use vrf_bitmap_init()/vrf_bitmap_free() to initialize/free a
bit-map;
- Use vrf_bitmap_set()/vrf_bitmap_unset() to set/unset a flag
in the given bit-map, corresponding to the given VRF ID;
- Use vrf_bitmap_check() to test whether the flag, in the given
bit-map and for the given VRF ID, is set.
- Client side:
- In "struct zclient", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
default_information
These flags are extended for each VRF, and controlled by the
clients themselves (or with the help of zclient_redistribute()
and zclient_redistribute_default()).
- Zebra side:
- In "struct zserv", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
redist_default
ifinfo
ridinfo
These flags are extended for each VRF, as the VRF registration
flags. They are maintained on receiving a ZEBRA_XXX_ADD or
ZEBRA_XXX_DELETE message.
When sending an interface/address/route/router-id message in
a VRF to a client, if the corresponding VRF registration flag
is not set, this message will not be dropped by zebra.
- A new function zread_vrf_unregister() is introduced to process
the new command ZEBRA_VRF_UNREGISTER. All the VRF registration
flags are cleared for the requested VRF.
Those clients, who support only the default VRF, will never receive
a message in a non-default VRF, thanks to the filter in zebra.
* New callback for the event of successful connection to zebra:
- zclient_start() is splitted, keeping only the code of connecting
to zebra.
- Now zclient_init()=>zclient_connect()=>zclient_start() operations
are purely dealing with the connection to zbera.
- Once zebra is successfully connected, at the end of zclient_start(),
a new callback is used to inform the client about connection.
- Till now, in the callback of connect-to-zebra event, all clients
send messages to zebra to request the router-id/interface/routes
information in the default VRF.
Of corse in future the client can do anything it wants in this
callback. For example, it may send requests for both default VRF
and some non-default VRFs.

This patch lets the netlink sockets work per VRF.
* The definition of "struct nlsock" is moved into zebra/rib.h.
* The previous global variables "netlink" and "netlink_cmd" now
become the members of "struct zebra_vrf", and are initialized
in zebra_vrf_alloc().
* All relative functions now work for a specific VRF, by adding
a new parameter which specifies the working VRF, except those
functions in which the VRF ID can be obtained from the interface.
* kernel_init(), interface_list() and route_read() are now also
working per VRF, and moved from main() to zebra_vrf_enable().
* A new function kernel_terminate() is added to release the
netlink sockets. It is called from zebra_vrf_disable().
* Correct VRF ID, instead of the previous VRF_DEFAULT, are now
passed to the functions of processing interfaces or route
entries.

* interface.h: (ifstat_update_proc) declaration should match
ifstat_update_sysctl really, which is to not return status, as
such status is not used anywhere.
* if_{proc,sysctl}.c: Make ifstat_update_* definitions and return values
consistent with each other and their declarations, ie:
(void) (*) (void).

* kernel_socket.h: New header for functions exported to sysctl
methods.
* kernel_socket.c: include previous.
Remove static qualifier from couple of functions which are
used by sysctl methods, incorrectly added in previous commit.
Add a workaround for a bogus gcc warning to the RTA_ macros.
* Makefile.am: Add kernel_socket.h to noinst_HEADERS
* if_sysctl.c: include rt.h and kernel_socket.h and remove
redundant prototypes.
* rtread_sysctl.c: ditto.
(route_read) fix mismatch of return values.
* {rt,zserv,rib}.h: Include lib headers depended on.

* global: Replace strerror with safe_strerror. And vtysh/vtysh.c
needs to include "log.h" to pick up the declaration.
