* Update OpenSSL (thanks @sapier, i use his patch!), Curl and SQLite3.
* Remove old arm config. Almost all phones that use ARMv5 have 1 core and 256-512 RAM, it's about 2-5 FPS.
* Do -O3 optimization for libs and remove -fexpensive-optimizations for Minetest (-O3 includes this! Read gcc docs).
* OpenSSL fix - thanks @sapier, again.
Fixed a minor mistake that made it appear as if the inventory
is serialized multiple times - once per each variable. In fact
it is serialized once per each node.
Lower water table where base humidity is low.
Alter heat and humidity to compensate for river humidity and altitude
chill.
Correct misuse of surface_max_y in generateTerrain.
Remove sand trails in the water at river mouths.
Remove river water below water_level.
Correct heat/humidity calculations where noises are less than zero.
Correct heightmap errors as much as possible.
Make humidity calculations more readable.
In the calculation of y_start,
when 'column height max' was large it caused
nmin.Y + max_height > nmax.Y - max_height
Now, in this situation y_start is set to the
midpoint between nmin.Y and nmax.Y
Limit y0 and y1 to between nmin.Y and nmax.Y,
otherwise index calculation, which has no checks for limits,
places them at unwanted locations in the voxelmanip
As stated in this forum thread [1], I noticed that there is a
2 second interval in which inventory changes are shown on the
client. @yyt16384 found the source of these 2 seconds:
m_nothing_to_send_pause_timer is set to 2.0 every time there
are no changes to make, but this timer is not reset when
SetBlockNotSent or setBlocksNotSent are invoked. So in worst
case, the changed block will be sent over 2 seconds too late.
With this change, changed inventories are updated almost
immediately, but it causes additional connection load.
Newest leveldb commit breaks build.
With no fix in sight, there is no other way
than to fall back to the last working leveldb
revision, and hardcode it.
Workaround for upstream bug
https://github.com/google/leveldb/issues/340
This allows mods to perform both asynchronous and synchronous HTTP
requests. Mods are only granted access to HTTP APIs if either mod
security is disabled or if they are whitelisted in any of the
the secure.http_mods and secure.trusted_mods settings.
Adds httpfetch_caller_alloc_secure to generate random, non-predictable
caller IDs so that lua mods cannot spy on each others HTTP queries.
