2014 network limit 1.0a +utils +toc -doc -drmonero

Browse Source 
commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)

[Some] files/code here (in external/otshell_utils) are under licence defined in
src/doc/LICENCE-otshell.txt ;
Others are from monero, with licence in src/doc/LICENCE-monero.txt ;
For me (rfree) the licence seem compatbile so no problem, personally (as author of many parts of the code,
possibly not all) I do not worry who uses it how; I'am not a lawyer.

Please share :-) This licence can be used e.g. for parts of code that are usable in both open-source FOSS project
Monero and Open Transactions, to share and develop both faster.

@brief interface for throttling of connection (count and rate-limit speed etc)
@details <PRE>
Throttling work by:
1) taking note of all traffic (hooks added e.g. to connection class) and measuring speed
2) depending on that information we sleep before sending out data (or send smaller portions of data)
3) depending on the information we can also sleep before sending requests or ask for smaller sets of data to download
