utils: Greatly improve performance of osmo_hexdump routines
In the osmo-bts and libosmo-abis code the hexdump routine is used for every incoming/outgoing packet (including voice frames) and the usage of snprintf showed up inside profiles. There is a semantic change when more than 4096 characters are used. The code will now truncate at byte boundaries (and not nibbles). Code: static const int lengths[] = { 23, 1000, 52 }; char buf[4096]; int i; for (i = 0; i < 30000; ++i) char *res = osmo_hexdump(buf, lengths[i & 3]); Results: before: after: real 0m3.233s real 0m0.085s user 0m3.212s user 0m0.084s sys 0m0.000s sys 0m0.000s
