This removes a giant `switch { }` block from lib/zclient.c and
harmonizes all zclient callback function types to be the same (some had
a subset of the args, some had a void return, now they all have
ZAPI_CALLBACK_ARGS and int return.)
Apart from getting rid of the giant switch, this is a minor security
benefit since the function pointers are now in a `const` array, so they
can't be overwritten by e.g. heap overflows for code execution anymore.

There is a possibility that the same line can be matched as a command in
some node and its parent node. In this case, when reading the config,
this line is always executed as a command of the child node.
For example, with the following config:
```
router ospf
network 193.168.0.0/16 area 0
!
mpls ldp
discovery hello interval 111
!
```
Line `mpls ldp` is processed as command `mpls ldp-sync` inside the
`router ospf` node. This leads to a complete loss of `mpls ldp` node
configuration.
To eliminate this issue and all possible similar issues, let's print an
explicit "exit" at the end of every node config.
This commit also changes indentation for a couple of existing exit
commands so that all existing commands are on the same level as their
corresponding node-entering commands.
Fixes#9206.

Instead of setting a config_write callback for each node, set a single
callback and print all config from there. It is necessary for the
following work on explicit "exit" command in every node.

pce-config, pce and pcc node-entering commands in vtysh include no-form,
which is incorrect. Currently, when user passes a no-form command like
`no pcc`, vtysh enters the node while pathd deletes the node and this
leads to a desynchronization.
Regular and no-form commands should be defined separately to fix this.

like the other automake variables, setting `xyz_LDFLAGS` causes
`AM_LDFLAGS` to be ignored for `xyz`. For some reason I had in my mind
that automake doesn't do this for LDFLAGS, but... it does. (Which is
consistent with `_CFLAGS` and co.)
So, all the libraries and modules have been ignoring `AM_LDFLAGS` (which
includes `SAN_FLAGS` too). Set up new `LIB_LDFLAGS` and
`MODULE_LDFLAGS` to handle all of this correctly (and move these bits to
a central location.)

`config.h` has all the defines from autoconf, which may include things
that switch behavior of other included headers (e.g. _GNU_SOURCE
enabling prototypes for additional functions.)
So, the first include in any `.c` file must be either `config.h` (with
the appropriate guard) or `zebra.h` (which includes `config.h` first
thing.)
