m_spanningtree Ensure that TreeSocket::Close() only runs once
m_spanningtree Remove now needless TreeSocket::ConnectionFailureShown
m_spanningtree Move squit logic into TreeServer from TreeSocket
m_spanningtree Remove split servers from the hash maps in TreeServer::SQuitInternal()
m_spanningtree Add the TreeServer that split to the cull list and destroy everything under it recursively at cull time instead of at squit processing time
m_spanningtree Remove now unused TreeServer::Tidy()
m_spanningtree Mark servers awaiting destruction after being lost in a netsplit, add TreeServer::IsDead()
m_spanningtree Quit all split users in one go
m_spanningtree Change type of num_lost_* to be unsigned
m_spanningtree Check TreeServer::IsDead() to learn whether a user is being quit due to a netsplit in OnUserQuit()
m_spanningtree Remove the now needless SplitInProgress workaround
m_spanningtree Squit dead servers immediately when they die, not at the next timer tick
m_spanningtree Throw a ProtocolException if a server SQUITs a server it shouldn't
Allow fast sid reuse by erasing fake users from UserManager::uuidlist when the netsplit is handled, not in cull()
Do not attempt to detect non-culled users at destruction by looking for their uuid, leave it to Extensible

This does not take uuid/sid reuse into consideration and Extensible implements this detection already in a proper way
Differ database error messages for m_permchannels and m_xline_db

m_permchannels and m_xline_db both have the same error messages as well as not
informing the server operator what file is at fault for the error. This makes it
hard to find which module is causing the error and what file the module is referring
to. The new messages explain which database is trying to be written and the path
used to write the file.
Fix off by one in ping timeout.

Been bugging me that users ping timeout at 121 rather than 120 seconds by default.
threadengine_win32 Use a stripped-down, local version of InspIRCd::BindSocket() for setting up the ITC pipe
Remove InspIRCd::BindSocket()
m_password_hash: Use out_size as HMAC-key length, as RFC2104 recommends

"In any case the minimal recommended length for K is L bytes (as the hash output length)."
