Adding a `\n' should now produce a warning. Controlled by `-Werror` so
if you're doing a dev build and it's warning about some `prefix2str`
that should be converted to `%pFX`, you can turn off `-Werror` to fix it
later like with all other warnings.

This might be faster if at some point in the future the Linux vDSO
supports CLOCK_THREAD_CPUTIME_ID without making a syscall. (Same
applies for other OSes.)

...really no reason to force this into a compile time decision. The
only point is avoiding the getrusage() syscall, which can easily be a
runtime decision.

If we have the following configuration:
```
vrf red
smth
exit-vrf
!
interface red vrf red
smth
```
And we delete the VRF using "no vrf red" command, we end up with:
```
interface red
smth
```
Interface config is preserved but moved to the default VRF.
This is not an expected behavior. We should remove the interface config
when the VRF is deleted.

glibc removed its pid cache a while back, and grabbing this from TLS is
faster than repeatedly calling the kernel...
Also use `intmax_t` which is more appropriate for both PID & TID.

printfrr() recently acquired the capability to record start/end of
formatting outputs. Make use of this in the zlog code so logging
targets have access to this information.
(This also records how long the `[XXXXX-XXXXX][EC 9999999]` prefix was
so log targets can choose to skip over it.)

`log-filter WORD` was giving me a serious headache since it also matches
`log WORD` due to the way the CLI token handling works. This meant that
a mistyped `log something` command would silently be interpreted as a
filter string, causing me serious headscratching and WTFs until I
figured what was going on.
Remove this UX pitfall so noone else falls into it. (Since the command
was never saved to config, renaming it shouldn't cause trouble.)
[Also I apparently forgot to update the docs when I transferred this
over to the new zlog bits...]
TODO for a rainy day: since we collect all the CLI commands anyway, we
should warn somewhere for "2nd level ambiguous" commands like this.

Almost all functions currently marked with pure attribute acquire a
route_node lock. By marking them pure we allow compiler to optimize the
code and not call them when it already knows the return value. This is
completely incorrect.
Only two of eleven functions can be marked as pure. And they still won't
be optimized because they are never called from the same function twice.
Let's remove the ext_pure macro completely to reduce the chance of
repeating this mistake in the future.

This commit fixes the following problem:
- enter the interface node
- move the interface to another VRF
- try to continue configuring the interface
It is not possible to continue configuration because the XPath stored in
the vty doesn't correspond with the actual state of the system anymore.
For example:
```
nfware# conf
nfware(config)# interface enp2s0
<-- move the enp2s0 to a different VRF -->
nfware(config-if)# ip router isis 1
% Failed to get iface dnode in candidate DB
```
To fix the issue, go through all connected vty shells and update the
stored XPath.

Always terminate default VRF last during FRR shutdown.
On shutdown we were simply looping over the RB tree and terminating
VRFs from the ROOT. This is not guaranteed to be the default last ever.
Instead switch to RB_SAFE and skip the default VRF till the very end.

The %p printf format specifier does already print the pointer address
with a leading "0x" prefix (indicating a hexadecimal number). There's
no need to add that prefix manually.

- Add following set clause for route-maps
"set evpn gateway-ip <ipv4|ipv6 >A.B.C.D|X:X::X:X"
- When this route-map is applied as outboubd policy in BGP, it will set the
gateway-ip in BGP attribute For EVPN type-5 routes.
Example configuration:
route-map RMAP-EVPN_GWIP permit 5
set evpn gateway-ip ipv4 50.0.2.12
set evpn gateway-ip ipv6 50:0:2::12

When the VRF node is exited using "exit" or "quit", there's still a VRF
pointer stored in the vty context. If you try to configure some router
related command, it will be applied to the previous VRF instead of the
default VRF. For example:
```
(config)# vrf test
(config-vrf)# ip router-id 1.1.1.1
(config-vrf)# do show run
...
!
vrf test
ip router-id 1.1.1.1
exit-vrf
!
...
(config-vrf)# exit
(config)# ip router-id 2.2.2.2
(config)# do show run
...
!
vrf test
ip router-id 2.2.2.2
exit-vrf
!
...
```
`vrf-exit` works correctly, because it stores a pointer to the default
VRF into the vty context (but weirdly keeping the VRF_NODE instead of
changing it to CONFIG_NODE).
Instead of relying on the behavior of exit function, always use the
default VRF when in CONFIG_NODE.
Another problem is missing `VTY_CHECK_CONTEXT`. If someone deletes the
VRF in which node the user enters the command, then zebra applies the
command to the default VRF instead of throwing an error.
