original nfdump filter code. New function lnf_filter_init_v1 or
lnf_filter_init_v2 is used to initialize either old (nfdump) or
new (libnf) filter. By default lnf_filter_init calls the old
one filter.

- c: nfdumpp checks -O option
- c: removed bug - libnf fails after attempt to read empty lnf_mem
- c: removed memory leak in original nfdump in LZO
- c: initial number of buckets in hash table increased to 500000
- c: new functions lnf_mem_read_raw, lnf_mem_write_raw added
- c: examples/lnf_ex06_readreset added
- c: examples/lnf_ex05_memtrans added
- c: examples/lnf_ex04_threads option -n added
- c: bug in bpd and pps calculation
- perl: removed memory leak in perl API (Bug #104294)
- perl: nfasnupd accepts -c <file> with additional prefix database

- perl: doc update
1.06 2014-12-06
- c: lnf_rec_fget lnf_rec_fset performance update (15%)

Net::NfDump (Aggreg => 1 and SortBy => <field> attributes)
- c: lnf_field_t structure extended with default sort and
aggregation order
- c: added example lnf_ex04_threads.c
- c: threads support added for paralel processing flow
records in aggregation. Code not released for public,
the public version works properly only in sigle
thread enviroment.
- c: added example lnf_ex03_aggreg.c
- c: added lnf_mem object with aggregation and sorting capability
- c: lnf_rec_fget, lnf_rec_fset incerased prtformance (30%)
