This introduces a new LOGP() macro together with LOGL_* definition to
support multiple log levels (severities) throughout the codebase.
Please note that the actual logging system does not use them yet,
in this patch we simply introduce the new macros at the caller site.
This patch fixes the PCAP logging. If frames are received from E1
interface, an 8 byte mISDN header (MISDN_HEADER_LEN) is in front of the
RSL packet. When frames are transmitted to the E1 interface, the
pcap_write_packet function will get a message buffer without the mISDN
header in front of the RSL packet. The pcap file was tested and the
output is correct.
Follow up patches should make use the msgb->l2, make the ipaccess
code use the pcap writing too...
