bbb6af89fe New Fake Packet circumvention method: wrong SEQ/ACK numbers 
This method sends Fake Packet with the TCP SEQ/ACK numbers "in the past":
-66000 is used for ACK (right out of the ACK permissive window in Linux stack),
-10000 is used for SEQ (without any reasoning).

This method is pretty effective in Russia.
It also could be handy in a networks which prohibit changing TTL values
(mobile networks with tethering block/premium feature).

b57a204d96 Apply each Fake Packet method to each packet separately 
Before: --set-ttl and --wrong-chksum generated single Fake Packet with both low TTL and incorrect checksum.
Now:    --set-ttl and --wrong-chksum generate two packets: one with low TTL, another with incorrect checksum.

e28cb52645 Send native-fragged fragments in the reversed order 
Some websites (or more precisely, TLS terminators/balancers) can't
handle segmented TLS ClientHello packet properly, requiring the whole
ClientHello in a single segment, otherwise the connection gets dropped.

However they still operate with a proper TCP stack.
Cheat on them: send the latter segment first (with TCP SEQ "in the future"),
the former segment second (with "current" SEQ), allowing OS TCP
stack to combine it in a single TCP read().

This fixes long-standing number of TCP fragmentation issues:
Fixes #4, #158, #224, #59, #192 and many others.

e3638786da Add Native Fragmentation support (without window size) 
This patch adds `--native-frag` option for userspace TCP
segmentation (packet splitting), without shrinking
TCP Window Size in SYN/ACK.

Compared to Window Size shrinking, this method does not require
waiting for ACK, which saves two RTTs.

This is preferrable method of operation since it has no cons.
It's faster and easier to handle in the software.
