2b3490db1f Add limit parameter to decompressZlib
This can prevent untrusted data, such as sent over the network,
from consuming all memory with a specially crafted payload.

c27504a322 compressZlib: don't use a SharedBuffer but a raw u8 * pointer
Remove usage of the SharedBuffer in zlib compression which has two problems:
* We copied the whole memory block to compress it (not good with mapblocks)
* We copied sometimes strings to SharedBuffer to SharedBuffer (2nd time)

Use this method in MapNode::serializeBulk + optimize serialization but merging 3 identical loops in a single loop

283bf97a1c Serialisation: documentation fixes, clarifying renames and whitespace fixes
1. Do two renames:
	* SER_FMT_CLIENT_VER_LOWEST -> SER_FMT_VER_LOWEST_WRITE
	* SER_FMT_VER_LOWEST -> SER_FMT_VER_LOWEST_READ
Now the two define values are consistently named with the _WRITE defines
SER_FMT_VER_{HIGHEST,LOWEST}_WRITE, and to better point out what the two
serialisation versions actually are for.

2. wrap some lines in doc/worldformat.txt, and point out that the node
timers are serialized at a later point, as this can cause confusion about
what now happens (if one doesn't strictly read the if block's conditions).

3. some whitespace fixes in NodeTimerList::serialize, and one new comment.

80a7408e4d Fix a crash (assert) when client set serial version < 24 in INIT
When SER_FMT_VER_LOWEST is set to zero, then the test is stupid in INIT because all client works. In mapblock we check if client's serialization version is < 24, but if client sent serialization version < 24 (15 for example) the server set it and tried to send nodes, then BOOM

To resolve the problem:
* Create a different CLIENT_MIN_VERSION to handle this problem
* Remove the exception
* Use an assert in case of bad developer code

nerzhul is (may?) be working on a new solution. For the moment this is reverted because old worlds cannot be loaded (see discussion on github for the commit).

This reverts commit 800d19270250bb13cc6b2d330199815bf8e96446.
