[F] - fixes a bug from existing official version
[B] - important bug discovered in official version
[T] - testes
[n] - not used now (only in history), replaced or not accepted to master

- adding support for user-local installed compiler (e.g. non-root users on older systems to use new compiler)
instructions to use monero on Debian 7 (build clang + deps)
- [n] faster build: cmake with fast build, and with cotire (precompiled headers), and limited targets
- fixed cmake local compiler e.g. BOOST_IGNORE_SYSTEM_PATHS after merges with the other new CMake

- faster rebuild: separate out not-template base for main network classes: connection_basic.cpp class connection_basic
- faster rebuild: separate out hooks: connection_basic::do_send_handler_write() do_send_handler_write_from_queue()
- created library/cmake for the new no-templates-only networking code - libp2p

- added command exit without DB save (only for testers)
- added option --no-igd to not wait for IGD on start (faster testing)

- imported logging/debug tools from otshell, with macros like _note() _info() _warn()
- logging: added proper thread locking; showing thread number {1} in the output
- logging: also showing process number (PID) in short form (1,2,3,...) to debug forking daemon etc
- logging: fixed colors for normal windows text console (currently they do not work in msys windows text console)
- logging: added channels to have separate files created
- logging: option (compile-time) to debug the logging system itself
- logging: console colors work on windows/msys

- created network throttle class + throttle manager 
- cmdline options for network throttle class (limit-rate-up limit-rate-down limit-rate)
- option and command to in fact limit (outgoing) peers --out-peers out_peers [currently not working! after merge] [TODO]
- rpc commands for network throttle class (limit limit_up limit_down)
- setting ToS socket flag with option --tos-flag 

- connection type support, so that RPC connection is excluded from network limits

- gather and save throughput statistics (speed vs limit) into data file
- statistics of details to tune implementation: sleep in network threads, number of peers
- optimized statistics: accumulate sum and limit disk writes

(dr. monero code is not published in this commit, but prepared)
- dr. monero show the collected statistics (in real time)
- dr. monero many windows opened at once from predefined list
- dr. monero auto scale; selectable average window
- dr. monero colors, show both samples and average values (transparent)
- dr. monero showing current configured network limit (goal)
- dr. monero show date/git commit/comments for better info in screenshots
- dr. monero optimize speed and memory usage to handle files from long tests

- [F] found few UBs in code like wrong initialization order
- [B] found and partial debugged deadlocks on existing program (faster testing)

- [B] found locking problem with connection close race

- debug option --test-drop-download to test no-DB version without running out of RAM
- also option --test-drop-download-heigh to start drop only after certain height

- added again fast exit command (but it does not work too well yet. ONLY FOR DEVELOPERS!)

- created new from-scratch clean network engine model (a new program/library)
- connected the logging, the network throttles and all code to network model
- [T] run experiments in fully controlled and very fast environment

- fine tuned parameters of throttles (sleep, 3 window sizes)
- code to estimated current network-transfer size of block based get_avg_block_size()
- [T] tested sleep vs request-size limiting of downloads (request less or more then 200 blocks) 
- for now we use sleep method

- documented throttle classes and few other classes
- adjusted comment headers, copyrights, added the @monero tag to doxygen denoting monero maintainer/contact for not-monero code
- doxygen scripts fixed, tested and generated actual website

- [n] rebased most of above when change to branch development was decided
- [n] again rebase when we returned to developing against branch master
- finall version was tested by developer on Windows 64-bit, Debian, Ubuntu
- fixed clock compilation problems for freebsd and mac os x; Fixed related problem again on mac os x.
