55d1bbe155 Grace delay feature added
`proxy -g8000,3,10`

First parameter is average read size we want to keep, second parameter is
minimal number of packets in the same direction to apply algorythm,
last value is delay added after polling and prior to reading data.
An example above adds 10 millisecond delay before reading data if average
polling size is below 8000 bytes and 3 read operations are made in the same
direction. It's specially usefule with splice. `logdump 1 1` is useful
to see how grace delays work, choose delay value to avoid filling the read
pipe/buffer (typically 64K) but keep the request sizes close to chosen average
on large file upload/download.

eb829b062b Major code refactoring
- sockmapping rewritten from stratch to minimilse polling. poll() is now
only called if blocking is actually expected, splice pipes are now
polled if splice fails, buffers flushing is much more accurate.
- logging code moved to separate files
- signal masks added to client threads to prevent unneeded interruptions
- bandwidth limitation will not delay the thread after client or server
shutdown

d159c57e1f Add splice() support on Linux to proxy, socks, ftppt, smtpp, pop3p
usage example:
proxy -s
proxy -s2
-s - enable splice() for sockets mapping to avoid data to be copied to user space
-s2 - enable splice() and attempt to free user space buffer ASAP

6696b35d74 Added -s option support for proxying with splice() for Liux
(without copying network data to
userspace). Currently only for tcppm.
