Fix compilation with NETMGR_TRACE(_VERBOSE) enabled on non-Linux

Browse Source 
When NETMGR_TRACE(_VERBOSE) is enabled, the build would fail on some
non-Linux non-glibc platforms because:

  * Use <stdint.h> print macros because uint_fast32_t is not always
    unsigned long

  * The header <execinfo.h> is not available on non-glibc, thus commit
    adds dummy backtrace() and backtrace_symbols_fd() functions for
    platforms without HAVE_BACKTRACE
