Makefile.am: Use AM_CPPFLAGS Since automake 1.13 INCLUDES is depricates and causes a warning

mgcp: add voice muxer support This patch adds the voice muxer. You can use this to batch RTP traffic to reduce bandwidth comsuption. Basically, osmux transforms RTP flows to a compact batch format, that is later on decompacted to its original form. Port UDP/1984 is used for the muxer traffic between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This feature depends on libosmo-netif, which contains the osmux core support. Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using the vendor-specific extension X-Osmux: on) coming from the BSC-NAT, so you can selectively enable osmux per BSC from one the bsc-nat.cfg file, so we have a centralized point to enable/disable osmux. First thing you need to do is to accept requests to use Osmux, this can be done from VTY interface of osmo-bsc_nat and osmo-bsc_mgcp by adding the following line: mgcp ... osmux on osmux batch-factor 4 This just initializes the osmux engine. You still have to specify what BSC uses osmux from osmo-bsc_nat configuration file: ... bsc 1 osmux on bsc 2 ... bsc 3 osmux on In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does not have osmux enabled. Thus, you can selectively enable osmux depending on the BSC, and we have a centralized point for configuration from the bsc-nat to enable osmux on demand, as suggested by Holger. At this moment, this patch contains heavy debug logging for each RTP packet that can be removed later to save cycles. The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that is received to configure an endpoint.

misc: Linking fixes for Ubuntu 11.10 Compiler Ubuntu 11.10 has changed some linker/compiler flags. Some fixes for this can be seen here[1]. In general the to be linked libs need to be moved into the LDADD section of parameters. This is with the old BFD linker (not gold). This is likely to end in some ping-pong with other versions of the linker.

nat: Introduce a prefix lookup tree (trie) for number rewriting * It is a trie. The max depth of the trie is the length of the longest prefix. The lookup is O(lookuped_prefix), but as the prefix length is limited, the lookup time is constant. * Each node can hold the entire prefix, has place for the rewrite rule with up to three digits. * A trie with 20k entries will take about 3MB ram. * Filling the trie 100 times takes ~800ms on my i7 laptop * 10.000.000 lookups take 315ms.. (for the same prefix). * 93/99 lines are tested, 6/6 functions are tested, 49 of 54 branches are tested. Only memory allocation failures are not covered * A late addition is to handle the '+' sign and to increase the number of chars in the rewrite prefix. The timing/line coverage has not been updated after this change.
