1de08e1961 Plantlike: Fix visual_scale being applied squared
This re-applies 2 commits that were reverted.

Visual_scale was applied twice to plantlike by accident sometime between
2011 and 2013, squaring the requested scale value. Visual_scale is
correctly applied once in it's other uses in signlike and torchlike.

Two lines of code are removed, they also had no effect for the vast
majority of nodes with the default visual_scale of 1.0.
The texture continues to have it's base at ground level.

Send sqrt(visual_scale) to old clients.

Keep compatibility with protocol < 30 clients now that visual_scale
is no longer applied twice to plantlike drawtype and mods are being
updated to a new value.

e58a55aa82 Make plantlike drawtype more fun
Adds several new ways that the plantlike drawtype mesh can be changed.

This requires paramtype2 = "meshoptions" to be set in the node
definition. The drawtype for these nodes should be "plantlike".

These modifications are all done using param2. This field is now
a complex bitfield that allows some or more of the combinations to
be chosen, and the mesh draw code will choose the options based as
neeeded for each plantlike node.

bit layout:
bits 0, 1 and 2 (values 0x1 through 0x7) are for choosing the plant
mesh shape:
  0 - ordinary plantlike plant ("x" shaped)
  1 - ordinary plant, but rotated 45 degrees ("+" shaped)
  2 - a plant with 3 faces ("*" shaped)
  3 - a plant with 4 faces ("#" shaped)
  4 - a plant with 4 faces ("#" shaped, leaning outwards)
  5 through 7 are unused and reserved for future mesh shapes.

bit 3 (0x8) causes the plant to be randomly offset in the x,z
plane. The plant should fall within the 1x1x1 nodebox if regularly
sized.

bit 4 (0x10) causes the plant mesh to grow by sqrt(2), and will cause
the plant mesh to fill out 1x1x1, and appear slightly larger. Texture
makers will want to make their plant texture 23x16 pixels to have the
best visual fit in 1x1x1 size.

bit 5 (0x20) causes each face of the plant to have a slight negative
Y offset in position, descending up to 0.125 downwards into the node
below. Because this is per face, this causes the plant model to be
less symmetric.

bit 6 (0x40) through bit 7 (0x80) are unused and reserved for
future use.

d499ec4838 Particles: Add option to remove particles on collision
Adds the particle option `collision_removal = bool`

Some particles are hard to use right now since they either go through
solid blocks (without collision detection), and with collision
detection enabled they (e.g. raindrops) would just stop dead on the
floor and sit there until they expire, or worse, scrape along a wall
or ceiling.

We can solve the problem by adding a boolean flag that tells the
particle to be removed if it ever collides with something. This will
make it easier to add rain that doesn't fall through your roof or stick
on the top of it. Or clouds and smoke that don't go through trees.

Particles that collide with this flag are marked expired
unconditionally, causing them to be treated like normal expired
particles and cleaned up normally.

Documentation is adjusted accordingly.

An added bonus of this patch is that particles can potentially collide
many times with nodes, and this reduces the amount of collisions to 1
(max), which may end up reducing particle load on the client.

423d8c1b0d Tolerate packet reordering in the early init process
Fixes a bug where packet reordering made the server give the
client two peer ids instead of one. This in turn confused
reliable packet sending and made connecting to the server fail.

The client usually sends three packets at init: one "dummy"
packet consisting of two 0 bytes, and the init packet as well as
its legacy counterpart. The last one can be turned off since commit
af30183124d40a969040d7de4b3a487feec466e4, but this is of lower
relevance for the bug. The relevant part here is that network
packet reorder (which is a normal occurence) can make the packets
reach the server in different order.

If reorder puts the dummy packet further behind, the following
would happen before the patch:

1. The server will get one of the init packets on channel 1 and
   assign the client a peer id, as the packet will have zero as
   peer id.

2. The server sends a CONTROLTYPE_SET_PEER_ID packet to inform
   the client of the peer id.

3. The next packet from the client will contain the peer id set by
   the server.

4. The server sets the m_has_sent_with_id member for the client's
   peer structure to true.

5. Now the dummy packet arrives. It has a peer id of zero, therefore
   the server searches whether it already has a peer id for the
   address the packet was sent from. The search fails because
   m_has_sent_with_id was set to true and the server only searched
   for peers with m_has_sent_with_id set to false.

6. In a working setup, the server would assign the dummy packet to
   the correct peer id. However the server instead now assigns a
   second peer id and peer structure to the peer, and assign the
   packet to that new peer.

7. In order to inform the peer of its peer id, the server sends a
   CONTROLTYPE_SET_PEER_ID command packet, reliably, to the peer.
   This packet uses the new peer id.

8. The client sends an ack to that packet, not with the new peer id
   but with the peer id sent in 2.

9. This packet reaches the server, but it drops the ACK as the peer
   id does not map to any un-ACK-ed packets with that seqnum. The
   same time, the server still waits for an ACK with the new peer
   id, which of course won't come. This causes the server to
   periodically re-try sending that packet, and the client ACKing it
   each time.

Steps 7-9 cause annoyances and erroneous output, but don't cause
the connection failure itself.
The actual mistake that causes the connection failure happens in 6:
The server does not assign the dummy packet to the correct peer, but
to a newly created one.
Therefore, all further packets sent by the client on channel 0 are
now buffered by the server as it waits for the dummy packet to reach
the peer, which of course doesn't happen as the server assigned
that packet to the second peer it created for the client.
This makes the connection code indefinitely buffer the
TOSERVER_CLIENT_READY packet, not passing it to higher level code,
which stalls the continuation of the further init process
indefinitely and causes the actual bug.

Maybe this can be caused by reordered init packets as well, the only
studied case was where network has reliably reordered the dummy
packet to get sent after the init packets.

The patch fixes the bug by not ignoring peers where
m_has_sent_with_id has been set anymore. The other changes of the
patch are just cleanups of unused methods and fields and additional
explanatory comments.

One could think of alternate ways to fix the bug:

* The client could simply take the new peer id and continue
  communicating with that. This is however worse than the fix as
  it requires the peer id set command to be sent reliably (which
  currently happens, but it cant be changed anymore). Also, such a
  change would require both server and client to be patched in order
  for the bug to be fixed, as right now the client ignores peer id
  set commands after the peer id is different from
  PEER_ID_INEXISTENT and the server requires modification too to
  change the peer id internally.
  And, most importantly, right now we guarantee higher level server
  code that the peer id for a certain peer does not change. This
  guarantee would have to be broken, and it would require much
  larger changes to the server than this patch means.

* One could stop sending the dummy packet. One may be unsure whether
  this is a good idea, as the meaning of the dummy packet is not
  known (it might be there for something important), and as it is
  possible that the init packets may cause this problem as well
  (although it may be possible too that they can't cause this).

Thanks to @auouymous who had originally reported this bug and who
has helped patiently in finding its cause.

af30183124 Add option to not send pre v25 init packet
The legacy init packet (pre v25) sends information about the client's
password that a server could use to log in to other servers if the
username and password are the same. All the other benefits of SRP of
protocol v25 are missed if the legacy init packet is still sent during
connection creation.

This patch adds an option to not send the v25 init packet. Not sending
the v25 packet means breaking compat with pre v25 servers, but as the
option is not enabled by default, no servers are affected unless the
user explicitly flips the switch. More than 90% of the servers on the
serverlist support post v25 protocols.

The patch also fixes a bug with greying out of non compliant servers
being done wrongly, the min and max params were mixed.
