This patch changes the signatures of some functions to allow const pointers in
places where a const qualified pointer is enough access for what the function
does (e.g. nla_get_u8). It also changes some functions that take a pointer
parameter and return a pointer derived from it to use the strchr idiom.
This is not exhaustive in terms of places where const can be added, but it's
a decent chunk that should not make the external api any more restrictive.

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.
