mini-snmpd v1.4

Bug fix release, courtesy of Andre Grosse Bley, @Haeretiker.

Changes

• Increase MIB table size: 128 --> 192

Fixes

• Fix default install directory: $prefix/bin --> $prefix/sbin
• Fix inverted enable/disable options to configure script, issue #4
• Incorrect OID types: ifLastChange should be BER_TYPE_TIME_TICKS and ifSpeed should be BER_TYPE_GAUGE, issue #1
• Fix parse_line() to prevent partial matches: wlan0 matched both wlan0-1 and wlan0-2, issue #1
• Fix parse_lineint() to prevent partial matches, issue #1
• Response OID order match with request order, reversed order breaks at least the MRTG SNMP client, issue #1
• Traffic counters get stuck after 4GB traffic. Use strtoull() rather than strtoul() to parse numbers, issue #1
• OIDs in request can be in any order. Reset OID table position after each handled OID from request, issue #1

mini-snmpd v1.3

Changes

• Refactor and cleanup by Javier Palacios
• New maintainer, Joachim Nilsson
• Hosting is now on GitHub
• Changed to GNU Configure and Build System, use ./autogen.sh for

• Add support for logging to syslog even when running in the foreground
• Complete refactor of FreeBSD support. Now with native syscalls instead
  of requirment for Linux /proc file system

  which is also default
• Use sigaction() instead of signal() and siginterrupt(), by
