On some architectures, uint64_t is defined as:
typedef unsigned long long int __u64;
on another architectures as:
typedef unsigned long int __u64;
So, according to man 3 printf,
uint64_t should be printed as "%llu" on some architectures, and as "%lu" on another. The same for scanf.
To eliminate that challenge, there is inttypes.h, in which appropriate constants
are defined for current architecture.
32-bit types (and even 16 and 8 bit types) should be printed using such constants if
printed variable defined as uint_XXXt or intXXXt type. But in reality 32-bit and less
types does not gain run-time error (except in scanf), because they pushed to stack as
32-bit values at least. So, I decide not to fix that.

1. Fix some places where unsigned value compared < 0
2. Fix obsolete %Z specifier to more portable %z
3. Some erroneous types substitution
4. nl_msec2str() - 64-bit msec is now properly used,
Only safe changes. I mean int <--> uint32_t and signed/unsigned fixes.
Some functinos require size_t argument instead of int, but changes of
signatures of that functions is terrible thing.
Also, I do not pretend for a full list of fixes.
Just to shut up clang -Wall -Wextra
One more thing. ifindex. I don't change that because changes will
be too big for simple fix.

Finally got rid of all the qdisc/class/cls code duplication in
the tc module API. The API takes care of allocation/freeing the
tc object specific data.
I hope I got it right this time.

So far all common tc atttributes were accessed via specific functions, i.e.
rtnl_class_set_parent(), rtnl_qdisc_set_parent(), rtnl_cls_set_parent()
which implied a lot of code duplication. Since all tc objects are derived
from struct rtnl_tc and these common attributes are already stored in there
this patch removes all type specific functions and makes rtnl_tc_* attribute
functions public.
rtnl_qdisc_set_parent(qdisc, 10);
becomes:
rtnl_tc_set_parent((struct rtnl_tc *) qdisc, 10);
This patch also adds the following new attributes to tc objects therefore
removing them as tc specific attributes:
- mtu
- mpu
- overhead
This allows for the rate table calculations to be unified as well taking into
account the new kernel behavior to take care of overhead automatically.

Replaces obsolete calls to nla_get_addr() and nla_get_data()
with nl_addr_alloc_attr() respectively nl_data_alloc_attr().
Also fixes missing error handling while parsing routing multipath
configuration.

In order for the interface to become more thread safe, the error
handling was revised to no longer depend on a static errno and
error string buffer.
This patch converts all error paths to return a libnl specific
error code which can be translated to a error message using
nl_geterror(int error). The functions nl_error() and
nl_get_errno() are therefore obsolete.
This change required various sets of function prototypes to be
changed in order to return an error code, the most prominent
are:
struct nl_cache *foo_alloc_cache(...);
changed to:
int foo_alloc_cache(..., struct nl_cache **);
struct nl_msg *foo_build_request(...);
changed to:
int foo_build_request(..., struct nl_msg **);
struct foo *foo_parse(...);
changed to:
int foo_parse(..., struct foo **);
This pretty much only leaves trivial allocation functions to
still return a pointer object which can still return NULL to
signal out of memory.
This change is a serious API and ABI breaker, sorry!
