Modify implementations that return error from action_until->print_aopt()
callback to silently skip actions that don't have their corresponding
TCA_ACT_OPTIONS attribute set (some actions already behave like this).
Print action kind before returning from action_until->print_aopt()
callbacks. This is necessary to support terse dump mode in following patch
in the series.

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.

This big patch was compiled by vimgrepping for memset calls and changing
to C99 initializer if applicable. One notable exception is the
initialization of union bpf_attr in tc/tc_bpf.c: changing it would break
for older gcc versions (at least <=3.4.6).
Calls to memset for struct rtattr pointer fields for parse_rtattr*()
were just dropped since they are not needed.
The changes here allowed the compiler to discover some unused variables,
so get rid of them, too.

There are only three users which require it to be reentrant, the rest is
fine without. Instead, provide a reentrant format_host_r() for users
which need it.

A bunch of source files look like they're copy & pasted from other files,
and some include header files that they don't actually need. Since dlfcn
has very specific usage (and is a pain on a static-only system), drop it
where it isn't really needed.
