In oneline mode the line seperator should be \
but several parts of tc aren't doing it right.

Many tc modules were printing error messages to stdout.
This is problematic if using JSON or other output formats.
Change all these places to use fprintf(stderr, ...) instead.
Also, remove unnecessary initialization and places
where else is used after error return.

If the user didn't specify any control action, don't pop the command line
arguments: otherwise, parsing of the next argument (tipically the 'index'
keyword) results in an error, causing the following 'tc-testing' failures:
Test a6d6: Add skbedit action with index
Test 38f3: Delete skbedit action
Test a568: Add action with ife type
Test b983: Add action without ife type
Test 7d50: Add skbmod action to set destination mac
Test 9b29: Add skbmod action to set source mac
Test e93a: Delete an skbmod action
Also, add missing parse for 'ok' control action to m_police, to fix the
following 'tc-testing' failure:
Test 8dd5: Add police action with control ok
tested with:
# ./tdc.py
test results:
all tests ok using kernel 4.16-rc2, except 9aa8 "Get a single skbmod
action from a list" (which is failing also before this commit)

We have helper routines to support nested attribute addition into
netlink buffer: use them instead of open coding.
Use addattr_nest_compat()/addattr_nest_compat_end() where appropriate.

Not all callers want parse_action_control*() to advance the
arguments. For instance act_parse_police() does the argument
advancing itself.

Each tc action is terminated by a control action. Each action parses and
prints then intividually. Introduce set of helpers and allow to share
this code.

The 'vlan modify' action allows to replace an existing 802.1q tag
according to user provided settings.
It accepts same arguments as the 'vlan push' action.
For example, this replaces vid 6 with vid 5:
# tc filter add dev veth0 parent ffff: pref 1 protocol 802.1q \
basic match 'meta(vlan mask 0xfff eq 6)' \
action vlan modify id 5 continue

The current vlan push action supports only vid and protocol options.
Add priority option.
Example script that adds vlan push action with vid and priority:
tc filter add dev veth0 protocol ip parent ffff: \
flower \
indev veth0 \
action vlan push id 100 priority 5
