These are patches responding to my comments for
Magnus's patch (https://patchwork.ozlabs.org/patch/1032848/).
The goal is to make pr_* macros available to other C files
than libbpf.c, and to simplify API function libbpf_set_print().
Specifically, Patch #1 used global functions
to facilitate pr_* macros in the header files so they
are available in different C files.
Patch #2 removes the global function libbpf_print_level_available()
which is added in Patch 1.
Patch #3 simplified libbpf_set_print() which takes only one print
function with a debug level argument among others.
Changelogs:
v3 -> v4:
. rename libbpf internal header util.h to libbpf_util.h
. rename libbpf internal function libbpf_debug_print() to libbpf_print()
v2 -> v3:
. bailed out earlier in libbpf_debug_print() if __libbpf_pr is NULL
. added missing LIBBPF_DEBUG level check in libbpf.c __base_pr().
v1 -> v2:
. Renamed global function libbpf_dprint() to libbpf_debug_print()
to be more expressive.
. Removed libbpf_dprint_level_available() as it is used only
once in btf.c and we can remove it by optimizing for common cases.
